An intent is an abstract description of an operation to be performed. It
can be used with startActivity
to
launch an Activity
,
broadcastIntent
to
send it to any interested BroadcastReceiver
components,
and Context.startService(Intent)
or
Context.bindService(Intent, BindServiceFlags, Executor, ServiceConnection)
to communicate with a
background Service
.
An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
Developer Guides
For information about how to create and resolve intents, read the Intents and Intent Filters developer guide.
Intent Structure
The primary pieces of information in an intent are:
-
action -- The general action to be performed, such as
ACTION_VIEW
,ACTION_EDIT
,ACTION_MAIN
, etc. -
data -- The data to operate on, such as a person record in the contacts database, expressed as a
Uri
.
Some examples of action/data pairs are:
-
ACTION_VIEW
content://contacts/people/1 -- Display information about the person whose identifier is "1". -
ACTION_DIAL
content://contacts/people/1 -- Display the phone dialer with the person filled in. -
ACTION_VIEW
tel:123 -- Display the phone dialer with the given number filled in. Note how the VIEW action does what is considered the most reasonable thing for a particular URI. -
ACTION_DIAL
tel:123 -- Display the phone dialer with the given number filled in. -
ACTION_EDIT
content://contacts/people/1 -- Edit information about the person whose identifier is "1". -
ACTION_VIEW
content://contacts/people/ -- Display a list of people, which the user can browse through. This example is a typical top-level entry into the Contacts application, showing you the list of people. Selecting a particular person to view would result in a new intent {ACTION_VIEW
content://contacts/people/N } being used to start an activity to display that person.
In addition to these primary attributes, there are a number of secondary attributes that you can also include with an intent:
-
category -- Gives additional information about the action to execute. For example,
CATEGORY_LAUNCHER
means it should appear in the Launcher as a top-level application, whileCATEGORY_ALTERNATIVE
means it should be included in a list of alternative actions the user can perform on a piece of data. -
type -- Specifies an explicit type (a MIME type) of the intent data. Normally the type is inferred from the data itself. By setting this attribute, you disable that evaluation and force an explicit type.
-
component -- Specifies an explicit name of a component class to use for the intent. Normally this is determined by looking at the other information in the intent (the action, data/type, and categories) and matching that with a component that can handle it. If this attribute is set then none of the evaluation is performed, and this component is used exactly as is. By specifying this attribute, all of the other Intent attributes become optional.
-
extras -- This is a
Bundle
of any additional information. This can be used to provide extended information to the component. For example, if we have a action to send an e-mail message, we could also include extra pieces of data here to supply a subject, body, etc.
Here are some examples of other operations you can specify as intents using these additional parameters:
-
ACTION_MAIN
with categoryCATEGORY_HOME
-- Launch the home screen. -
ACTION_GET_CONTENT
with MIME typevnd.android.cursor.item/phone
-- Display the list of people's phone numbers, allowing the user to browse through them and pick one and return it to the parent activity. -
ACTION_GET_CONTENT
with MIME type */* and categoryCATEGORY_OPENABLE
-- Display all pickers for data that can be opened withContentResolver.openInputStream()
, allowing the user to pick one of them and then some data inside of it and returning the resulting URI to the caller. This can be used, for example, in an e-mail application to allow the user to pick some data to include as an attachment.
There are a variety of standard Intent action and category constants
defined in the Intent class, but applications can also define their own.
These strings use Java-style scoping, to ensure they are unique -- for
example, the standard ACTION_VIEW
is called
"android.intent.action.VIEW".
Put together, the set of actions, data types, categories, and extra data defines a language for the system allowing for the expression of phrases such as "call john smith's cell". As applications are added to the system, they can extend this language by adding new actions, types, and categories, or they can modify the behavior of existing phrases by supplying their own activities that handle them.
Intent Resolution
There are two primary forms of intents you will use.
-
Explicit Intents have specified a component (via
setComponent(ComponentName)
orsetClass(Context, Class)
), which provides the exact class to be run. Often these will not include any other information, simply being a way for an application to launch various internal activities it has as the user interacts with the application. -
Implicit Intents have not specified a component; instead, they must include enough information for the system to determine which of the available components is best to run for that intent.
When using implicit intents, given such an arbitrary intent we need to
know what to do with it. This is handled by the process of Intent
resolution, which maps an Intent to an Activity
,
BroadcastReceiver
, or Service
(or sometimes two or
more activities/receivers) that can handle it.
The intent resolution mechanism basically revolves around matching an
Intent against all of the <intent-filter> descriptions in the
installed application packages. (Plus, in the case of broadcasts, any BroadcastReceiver
objects explicitly registered with Context#registerReceiver
.) More
details on this can be found in the documentation on the IntentFilter
class.
There are three pieces of information in the Intent that are used for
resolution: the action, type, and category. Using this information, a query
is done on the PackageManager
for a component that can handle the
intent. The appropriate component is determined based on the intent
information supplied in the AndroidManifest.xml
file as
follows:
-
The action, if given, must be listed by the component as one it handles.
-
The type is retrieved from the Intent's data, if not already supplied in the Intent. Like the action, if a type is included in the intent (either explicitly or implicitly in its data), then this must be listed by the component as one it handles.
- For data that is not a
content:
URI and where no explicit type is included in the Intent, instead the scheme of the intent data (such ashttp:
ormailto:
) is considered. Again like the action, if we are matching a scheme it must be listed by the component as one it can handle. -
The categories, if supplied, must all be listed by the activity as categories it handles. That is, if you include the categories
CATEGORY_LAUNCHER
andCATEGORY_ALTERNATIVE
, then you will only resolve to components with an intent that lists both of those categories. Activities will very often need to support theCATEGORY_DEFAULT
so that they can be found byContext.startActivity()
.
For example, consider the Note Pad sample application that allows a user to browse through a list of notes data and view details about individual items. Text in italics indicates places where you would replace a name with one specific to your own package.
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android.notepad"> <application android:icon="@drawable/app_notes" android:label="@string/app_name"> <provider class=".NotePadProvider" android:authorities="com.google.provider.NotePad" /> <activity class=".NotesList" android:label="@string/title_notes_list"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.VIEW" /> <action android:name="android.intent.action.EDIT" /> <action android:name="android.intent.action.PICK" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.GET_CONTENT" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> </intent-filter> </activity> <activity class=".NoteEditor" android:label="@string/title_note"> <intent-filter android:label="@string/resolve_edit"> <action android:name="android.intent.action.VIEW" /> <action android:name="android.intent.action.EDIT" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.INSERT" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" /> </intent-filter> </activity> <activity class=".TitleEditor" android:label="@string/title_edit_title" android:theme="@android:style/Theme.Dialog"> <intent-filter android:label="@string/resolve_title"> <action android:name="com.android.notepad.action.EDIT_TITLE" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.ALTERNATIVE" /> <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> </intent-filter> </activity> </application> </manifest>
The first activity,
com.android.notepad.NotesList
, serves as our main
entry into the app. It can do three things as described by its three intent
templates:
<intent-filter> <action android:name="
android.intent.action.MAIN
" /> <category android:name="android.intent.category.LAUNCHER
" /> </intent-filter>This provides a top-level entry into the NotePad application: the standard MAIN action is a main entry point (not requiring any other information in the Intent), and the LAUNCHER category says that this entry point should be listed in the application launcher.
<intent-filter> <action android:name="
android.intent.action.VIEW
" /> <action android:name="android.intent.action.EDIT
" /> <action android:name="android.intent.action.PICK
" /> <category android:name="android.intent.category.DEFAULT
" /> <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" /> </intent-filter>This declares the things that the activity can do on a directory of notes. The type being supported is given with the <type> tag, where
vnd.android.cursor.dir/vnd.google.note
is a URI from which a Cursor of zero or more items (vnd.android.cursor.dir
) can be retrieved which holds our note pad data (vnd.google.note
). The activity allows the user to view or edit the directory of data (via the VIEW and EDIT actions), or to pick a particular note and return it to the caller (via the PICK action). Note also the DEFAULT category supplied here: this is required for theContext.startActivity
method to resolve your activity when its component name is not explicitly specified.<intent-filter> <action android:name="
android.intent.action.GET_CONTENT
" /> <category android:name="android.intent.category.DEFAULT
" /> <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> </intent-filter>This filter describes the ability to return to the caller a note selected by the user without needing to know where it came from. The data type
vnd.android.cursor.item/vnd.google.note
is a URI from which a Cursor of exactly one (vnd.android.cursor.item
) item can be retrieved which contains our note pad data (vnd.google.note
). The GET_CONTENT action is similar to the PICK action, where the activity will return to its caller a piece of data selected by the user. Here, however, the caller specifies the type of data they desire instead of the type of data the user will be picking from.
Given these capabilities, the following intents will resolve to the NotesList activity:
-
{ action=android.app.action.MAIN } matches all of the activities that can be used as top-level entry points into an application.
-
{ action=android.app.action.MAIN, category=android.app.category.LAUNCHER } is the actual intent used by the Launcher to populate its top-level list.
-
{ action=android.intent.action.VIEW data=content://com.google.provider.NotePad/notes } displays a list of all the notes under "content://com.google.provider.NotePad/notes", which the user can browse through and see the details on.
-
{ action=android.app.action.PICK data=content://com.google.provider.NotePad/notes } provides a list of the notes under "content://com.google.provider.NotePad/notes", from which the user can pick a note whose data URL is returned back to the caller.
-
{ action=android.app.action.GET_CONTENT type=vnd.android.cursor.item/vnd.google.note } is similar to the pick action, but allows the caller to specify the kind of data they want back so that the system can find the appropriate activity to pick something of that data type.
The second activity,
com.android.notepad.NoteEditor
, shows the user a single
note entry and allows them to edit it. It can do two things as described
by its two intent templates:
<intent-filter android:label="@string/resolve_edit"> <action android:name="
android.intent.action.VIEW
" /> <action android:name="android.intent.action.EDIT
" /> <category android:name="android.intent.category.DEFAULT
" /> <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> </intent-filter>The first, primary, purpose of this activity is to let the user interact with a single note, as decribed by the MIME type
vnd.android.cursor.item/vnd.google.note
. The activity can either VIEW a note or allow the user to EDIT it. Again we support the DEFAULT category to allow the activity to be launched without explicitly specifying its component.<intent-filter> <action android:name="
android.intent.action.INSERT
" /> <category android:name="android.intent.category.DEFAULT
" /> <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" /> </intent-filter>The secondary use of this activity is to insert a new note entry into an existing directory of notes. This is used when the user creates a new note: the INSERT action is executed on the directory of notes, causing this activity to run and have the user create the new note data which it then adds to the content provider.
Given these capabilities, the following intents will resolve to the NoteEditor activity:
-
{ action=android.intent.action.VIEW data=content://com.google.provider.NotePad/notes/{ID} } shows the user the content of note {ID}.
-
{ action=android.app.action.EDIT data=content://com.google.provider.NotePad/notes/{ID} } allows the user to edit the content of note {ID}.
-
{ action=android.app.action.INSERT data=content://com.google.provider.NotePad/notes } creates a new, empty note in the notes list at "content://com.google.provider.NotePad/notes" and allows the user to edit it. If they keep their changes, the URI of the newly created note is returned to the caller.
The last activity,
com.android.notepad.TitleEditor
, allows the user to
edit the title of a note. This could be implemented as a class that the
application directly invokes (by explicitly setting its component in
the Intent), but here we show a way you can publish alternative
operations on existing data:
<intent-filter android:label="@string/resolve_title"> <action android:name="com.android.notepad.action.EDIT_TITLE" /> <category android:name="android.intent.category.DEFAULT
" /> <category android:name="android.intent.category.ALTERNATIVE
" /> <category android:name="android.intent.category.SELECTED_ALTERNATIVE
" /> <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> </intent-filter>
In the single intent template here, we
have created our own private action called
com.android.notepad.action.EDIT_TITLE
which means to
edit the title of a note. It must be invoked on a specific note
(data type vnd.android.cursor.item/vnd.google.note
) like the previous
view and edit actions, but here displays and edits the title contained
in the note data.
In addition to supporting the default category as usual, our title editor
also supports two other standard categories: ALTERNATIVE and
SELECTED_ALTERNATIVE. Implementing
these categories allows others to find the special action it provides
without directly knowing about it, through the
PackageManager.queryIntentActivityOptions(ComponentName, Intent, Intent, int)
method, or
more often to build dynamic menu items with
Menu.addIntentOptions(int, int, int, ComponentName, Intent, Intent, int, MenuItem)
. Note that in the intent
template here was also supply an explicit name for the template
(via android:label="@string/resolve_title"
) to better control
what the user sees when presented with this activity as an alternative
action to the data they are viewing.
Given these capabilities, the following intent will resolve to the TitleEditor activity:
-
{ action=com.android.notepad.action.EDIT_TITLE data=content://com.google.provider.NotePad/notes/{ID} } displays and allows the user to edit the title associated with note {ID}.

public static final String ACTION_BATTERY_CHANGED
Broadcast Action: This is a sticky broadcast containing the
charging state, level, and other information about the battery.
See BatteryManager
for documentation on the
contents of the Intent.
You cannot receive this through components declared
in manifests, only by explicitly registering for it with
Context.registerReceiver()
. See ACTION_BATTERY_LOW
,

This is a protected intent that can only be sent by the system.
Constant Value: "android.intent.action.BATTERY_OKAY"
ACTION_BOOT_COMPLETED
public static final String ACTION_BOOT_COMPLETED
Broadcast Action: This is broadcast once, after the user has finished
booting. It can be used to perform application-specific initialization,
such as installing alarms. You must hold the
Manifest.permission.RECEIVE_BOOT_COMPLETED
permission in
order to receive this broadcast.
This broadcast is sent at boot by all devices (both with and without direct boot support). Upon receipt of this broadcast, the user is unlocked and both device-protected and credential-protected storage can accessed safely.
If you need to run while the user is still locked (before they've entered
their lock pattern or PIN for the first time), you can listen for the
ACTION_LOCKED_BOOT_COMPLETED
broadcast.
This is a protected intent that can only be sent by the system.
Constant Value: "android.intent.action.BOOT_COMPLETED"
ACTION_BUG_REPORT
public static final String ACTION_BUG_REPORT
Activity Action: Show activity for reporting a bug.
Input: Nothing.
Output: Nothing.
Constant Value: "android.intent.action.BUG_REPORT"
ACTION_CALL
public static final String ACTION_CALL
Activity Action: Perform a call to someone specified by the data.
Input: If nothing, an empty dialer is started; else getData()
is URI of a phone number to be dialed or a tel: URI of an explicit phone
number.
Output: nothing.
Note: there will be restrictions on which applications can initiate a
call; most applications should use the ACTION_DIAL
.
Note: this Intent cannot be used to call emergency
numbers. Applications can dial emergency numbers using
ACTION_DIAL
, however.
Note: This Intent can only be used to dial call forwarding MMI codes if the application
using this intent is set as the default or system dialer. The system will treat any other
application using this Intent for the purpose of dialing call forwarding MMI codes as if the
ACTION_DIAL
Intent was used instead.
Note: An app filling the RoleManager.ROLE_DIALER
role should use
TelecomManager.placeCall(Uri, Bundle)
to place calls rather than
relying on this intent.
Note: if you app targets M
and above and declares as using the Manifest.permission.CALL_PHONE
permission which is not granted, then attempting to use this action will
result in a SecurityException
.
Constant Value: "android.intent.action.CALL"
ACTION_CALL_BUTTON
public static final String ACTION_CALL_BUTTON
Activity Action: The user pressed the "call" button to go to the dialer or other appropriate UI for placing a call.
Input: Nothing.
Output: Nothing.
Constant Value: "android.intent.action.CALL_BUTTON"
ACTION_CAMERA_BUTTON
public static final String ACTION_CAMERA_BUTTON
Broadcast Action: The "Camera Button" was pressed. Includes a single
extra field, EXTRA_KEY_EVENT
, containing the key event that
caused the broadcast.
Constant Value: "android.intent.action.CAMERA_BUTTON"
ACTION_CARRIER_SETUP
public static final String ACTION_CARRIER_SETUP
Activity Action: Main entry point for carrier setup apps.
Carrier apps that provide an implementation for this action may be invoked to configure
carrier service and typically require
carrier privileges
to
fulfill their duties.
Constant Value: "android.intent.action.CARRIER_SETUP"
ACTION_CHOOSER
public static final String ACTION_CHOOSER
Activity Action: Display an activity chooser, allowing the user to pick what they want to before proceeding. This can be used as an alternative to the standard activity picker that is displayed by the system when you try to start an activity with multiple possible matches, with these differences in behavior:
- You can specify the title that will appear in the activity chooser.
- The user does not have the option to make one of the matching activities a preferred activity, and all possible activities will always be shown even if one of them is currently marked as the preferred activity.
This action should be used when the user will naturally expect to select an activity in order to proceed. An example if when not to use it is when the user clicks on a "mailto:" link. They would naturally expect to go directly to their mail app, so startActivity() should be called directly: it will either launch the current preferred app, or put up a dialog allowing the user to pick an app to use and optionally marking that as preferred.
In contrast, if the user is selecting a menu item to send a picture they are viewing to someone else, there are many different things they may want to do at this point: send it through e-mail, upload it to a web service, etc. In this case the CHOOSER action should be used, to always present to the user a list of the things they can do, with a nice title given by the caller such as "Send this photo with:".
If you need to grant URI permissions through a chooser, you must specify
the permissions to be granted on the ACTION_CHOOSER Intent
in addition to the EXTRA_INTENT inside. This means using
setClipData(ClipData)
to specify the URIs to be granted as well as
FLAG_GRANT_READ_URI_PERMISSION
and/or
FLAG_GRANT_WRITE_URI_PERMISSION
as appropriate.
As a convenience, an Intent of this form can be created with the
createChooser(Intent, CharSequence)
function.
Input: No data should be specified. get*Extra must have
a EXTRA_INTENT
field containing the Intent being executed,
and can optionally have a EXTRA_TITLE
field containing the
title text to display in the chooser.
Output: Depends on the protocol of EXTRA_INTENT
.
Constant Value: "android.intent.action.CHOOSER"
ACTION_CLOSE_SYSTEM_DIALOGS
public static final String ACTION_CLOSE_SYSTEM_DIALOGS
This constant was deprecated
in API level 31.
This intent is deprecated for third-party applications starting from Android
Build.VERSION_CODES#S
for security reasons. Unauthorized usage by applications
will result in the broadcast intent being dropped for apps targeting API level less than
Build.VERSION_CODES#S
and in a SecurityException
for apps targeting SDK
level Build.VERSION_CODES#S
or higher. Instrumentation initiated from the shell
(eg. tests) is still able to use the intent. The platform will automatically collapse
the proper system dialogs in the proper use-cases. For all others, the user is the one in
control of closing dialogs.
Broadcast Action: This is broadcast when a user action should request a
temporary system dialog to dismiss. Some examples of temporary system
dialogs are the notification window-shade and the recent tasks dialog.
Requires android.Manifest.permission.BROADCAST_CLOSE_SYSTEM_DIALOGS
Constant Value: "android.intent.action.CLOSE_SYSTEM_DIALOGS"
ACTION_CONFIGURATION_CHANGED
public static final String ACTION_CONFIGURATION_CHANGED
Broadcast Action: The current device Configuration
(orientation, locale, etc) has changed. When such a change happens, the
UIs (view hierarchy) will need to be rebuilt based on this new
information; for the most part, applications don't need to worry about
this, because the system will take care of stopping and restarting the
application to make sure it sees the new changes. Some system code that
can not be restarted will need to watch for this action and handle it
appropriately.
You cannot receive this through components declared
in manifests, only by explicitly registering for it with
Context.registerReceiver()
.
This is a protected intent that can only be sent by the system.
See also:
Constant Value: "android.intent.action.CONFIGURATION_CHANGED"
ACTION_CREATE_DOCUMENT
public static final String ACTION_CREATE_DOCUMENT
Activity Action: Allow the user to create a new document. When invoked,
the system will display the various DocumentsProvider
instances
installed on the device, letting the user navigate through them. The
returned document may be a newly created document with no content, or it
may be an existing document with the requested MIME type.
Each document is represented as a content://
URI backed by a
DocumentsProvider
, which can be opened as a stream with
ContentResolver#openFileDescriptor(Uri, String)
, or queried for
DocumentsContract.Document
metadata.
Callers must indicate the concrete MIME type of the document being
created by setting setType(java.lang.String)
. This MIME type cannot be
changed after the document is created.
Callers can provide an initial display name through EXTRA_TITLE
,
but the user may change this value before creating the file.
Callers must include CATEGORY_OPENABLE
in the Intent to obtain
URIs that can be opened with
ContentResolver#openFileDescriptor(Uri, String)
.
Callers can set a document URI through
DocumentsContract#EXTRA_INITIAL_URI
to indicate the initial
location of documents navigator. System will do its best to launch the
navigator in the specified document if it's a folder, or the folder that
contains the specified document if not.
Output: The URI of the item that was created. This must be a
content://
URI so that any receiver can access it.
See also:
Constant Value: "android.intent.action.CREATE_DOCUMENT"
ACTION_CREATE_NOTE
public static final String ACTION_CREATE_NOTE
Activity Action: Starts a note-taking activity that can be used to create a note. This action

public static final String ACTION_CREATE_REMINDER
Activity Action: Creates a reminder.
Input: EXTRA_TITLE
The title of the reminder that will be shown to the user.

public static final String ACTION_CREATE_SHORTCUT
Activity Action: Creates a shortcut.
Input: Nothing.
Output: An Intent representing the ShortcutInfo
result.

The specified set of packages are now available on the system.
Includes the following extras:
-
EXTRA_CHANGED_PACKAGE_LIST
is the set of packages whose resources(were previously unavailable) are currently available.EXTRA_CHANGED_UID_LIST
is the set of uids of the packages whose resources(were previously unavailable) are currently available.
This is a protected intent that can only be sent by the system.
Constant Value: "android.intent.action.EXTERNAL_APPLICATIONS_AVAILABLE"
ACTION_EXTERNAL_APPLICATIONS_UNAVAILABLE
public static final String ACTION_EXTERNAL_APPLICATIONS_UNAVAILABLE
Broadcast Action: Resources for a set of packages are currently
unavailable since the media on which they exist is unavailable.

launched and are practically unavailable on the system.
Inclues the following extras:
-
EXTRA_CHANGED_PACKAGE_LIST
is the set of packages whose resources are no longer available.EXTRA_CHANGED_UID_LIST
is the set of packages whose resources are no longer available.
This is a protected intent that can only be sent by the system.
Constant Value: "android.intent.action.EXTERNAL_APPLICATIONS_UNAVAILABLE"
ACTION_FACTORY_TEST
public static final String ACTION_FACTORY_TEST
Activity Action: Main entry point for factory tests. Only used when the device is booting in factory test node. The implementing package must be installed in the system image.
Input: nothing
Output: nothing
Constant Value: "android.intent.action.FACTORY_TEST"
ACTION_GET_CONTENT
public static final String ACTION_GET_CONTENT
Activity Action: Allow the user to select a particular kind of data and
return it. This is different than ACTION_PICK
in that here we
just say what kind of data is desired, not a URI of existing data from
which the user can pick. An ACTION_GET_CONTENT could allow the user to
create the data as it runs (for example taking a picture or recording a
sound), let them browse over the web and download the desired data,
etc.
There are two main ways to use this action: if you want a specific kind
of data, such as a person contact, you set the MIME type to the kind of
data you want and launch it with Context#startActivity(Intent)
.
The system will then launch the best application to select that kind
of data for you.
You may also be interested in any of a set of types of content the user can pick. For example, an e-mail application that wants to allow the user to add an attachment to an e-mail message can use this action to bring up a list of all of the types of content the user can attach.
In this case, you should wrap the GET_CONTENT intent with a chooser
(through createChooser(Intent, CharSequence)
), which will give the proper interface
for the user to pick how to send your data and allow you to specify
a prompt indicating what they are doing. You will usually specify a
broad MIME type (such as image/* or */*), resulting in a
broad range of content types the user can select from.
When using such a broad GET_CONTENT action, it is often desirable to
only pick from data that can be represented as a stream. This is
accomplished by requiring the CATEGORY_OPENABLE
in the Intent.
Callers can optionally specify EXTRA_LOCAL_ONLY
to request that
the launched content chooser only returns results representing data that
is locally available on the device. For example, if this extra is set
to true then an image picker should not show any pictures that are available
from a remote server but not already on the local device (thus requiring
they be downloaded when opened).
If the caller can handle multiple returned items (the user performing
multiple selection), then it can specify EXTRA_ALLOW_MULTIPLE
to indicate this.
Input: getType()
is the desired MIME type to retrieve. Note
that no URI is supplied in the intent, as there are no constraints on
where the returned data originally comes from. You may also include the
CATEGORY_OPENABLE
if you can only accept data that can be
opened as a stream. You may use EXTRA_LOCAL_ONLY
to limit content
selection to local data. You may use EXTRA_ALLOW_MULTIPLE
to
allow the user to select multiple items.
Output: The URI of the item that was picked. This must be a content: URI so that any receiver can access it.
Constant Value: "android.intent.action.GET_CONTENT"
ACTION_GET_RESTRICTION_ENTRIES
public static final String ACTION_GET_RESTRICTION_ENTRIES
Broadcast to a specific application to query any supported restrictions to impose
on restricted users. The broadcast intent contains an extra
EXTRA_RESTRICTIONS_BUNDLE
with the currently persisted
restrictions as a Bundle of key/value pairs. The value types can be Boolean, String or
String[] depending on the restriction type.
EXTRA_RESTRICTIONS_LIST
,
which is of type ArrayList<RestrictionEntry>
. It can also
contain an extra EXTRA_RESTRICTIONS_INTENT
, which is of type Intent
.
The activity specified by that intent will be launched for a result which must contain
one of the extras EXTRA_RESTRICTIONS_LIST
or EXTRA_RESTRICTIONS_BUNDLE
.
The keys and values of the returned restrictions will be persisted.

ACTION_NEW_OUTGOING_CALL
public static final String ACTION_NEW_OUTGOING_CALL
This constant was deprecated
in API level 29.
Apps that redirect outgoing calls should use the
CallRedirectionService
API. Apps that perform call screening
should use the CallScreeningService
API. Apps which need to be
notified of basic call state should use
TelephonyCallback.CallStateListener
to determine when a new
outgoing call is placed.
Broadcast Action: An outgoing call is about to be placed.
The Intent will have the following extra value:
EXTRA_PHONE_NUMBER
- the phone number originally intended to be dialed.
Starting in Android 15, this broadcast is no longer sent as an ordered
broadcast. The resultData
no longer has any effect and will not determine the
actual routing of the call. Further, receivers of this broadcast do not get foreground
priority and cannot launch background activities.
Once the broadcast is finished, the resultData is used as the actual
number to call. If null
, no call will be placed.
It is perfectly acceptable for multiple receivers to process the outgoing call in turn: for example, a parental control application might verify that the user is authorized to place the call at that time, then a number-rewriting application might add an area code if one was not specified.
For consistency, any receiver whose purpose is to prohibit phone calls should have a priority of 0, to ensure it will see the final phone number to be dialed. Any receiver whose purpose is to rewrite phone numbers to be called should have a positive priority. Negative priorities are reserved for the system for this broadcast; using them may cause problems.
Any BroadcastReceiver receiving this Intent must not abort the broadcast.
Emergency calls cannot be intercepted using this mechanism, and other calls cannot be modified to call emergency numbers using this mechanism.
Some apps (such as VoIP apps) may want to redirect the outgoing
call to use their own service instead. Those apps should first prevent
the call from being placed by setting resultData to null
and then start their own app to make the call.
You must hold the
Manifest.permission.PROCESS_OUTGOING_CALLS
permission to receive this Intent.
This is a protected intent that can only be sent by the system.
If the user has chosen a CallRedirectionService
to
handle redirection of outgoing calls, this intent will NOT be sent as an ordered broadcast.
This means that attempts to re-write the outgoing call by other apps using this intent will
be ignored.
Constant Value: "android.intent.action.NEW_OUTGOING_CALL"
ACTION_OPEN_DOCUMENT
public static final String ACTION_OPEN_DOCUMENT
Activity Action: Allow the user to select and return one or more existing
documents. When invoked, the system will display the various
DocumentsProvider
instances installed on the device, letting the
user interactively navigate through them. These documents include local
media, such as photos and video, and documents provided by installed
cloud storage providers.
Each document is represented as a content://
URI backed by a
DocumentsProvider
, which can be opened as a stream with
ContentResolver#openFileDescriptor(Uri, String)
, or queried for
DocumentsContract.Document
metadata.
All selected documents are returned to the calling application with
persistable read and write permission grants. If you want to maintain
access to the documents across device reboots, you need to explicitly
take the persistable permissions using
ContentResolver#takePersistableUriPermission(Uri, int)
.
Callers must indicate the acceptable document MIME types through
setType(java.lang.String)
. For example, to select photos, use
image/*
. If multiple disjoint MIME types are acceptable, define
them in EXTRA_MIME_TYPES
and setType(java.lang.String)
to
*/*.
If the caller can handle multiple returned items (the user performing
multiple selection), then you can specify EXTRA_ALLOW_MULTIPLE
to indicate this.
Callers must include CATEGORY_OPENABLE
in the Intent to obtain
URIs that can be opened with
ContentResolver#openFileDescriptor(Uri, String)
.
Callers can set a document URI through
DocumentsContract#EXTRA_INITIAL_URI
to indicate the initial
location of documents navigator. System will do its best to launch the
navigator in the specified document if it's a folder, or the folder that
contains the specified document if not.
Output: The URI of the item that was picked, returned in
getData()
. This must be a content://
URI so that any
receiver can access it. If multiple documents were selected, they are
returned in getClipData()
.
See also:
Constant Value: "android.intent.action.OPEN_DOCUMENT"
ACTION_OPEN_DOCUMENT_TREE
public static final String ACTION_OPEN_DOCUMENT_TREE
Activity Action: Allow the user to pick a directory subtree. When
invoked, the system will display the various DocumentsProvider
instances installed on the device, letting the user navigate through
them. Apps can fully manage documents within the returned directory.
To gain access to descendant (child, grandchild, etc) documents, use
DocumentsContract#buildDocumentUriUsingTree(Uri, String)
and
DocumentsContract#buildChildDocumentsUriUsingTree(Uri, String)
with the returned URI.
Callers can set a document URI through
DocumentsContract#EXTRA_INITIAL_URI
to indicate the initial
location of documents navigator. System will do its best to launch the
navigator in the specified document if it's a folder, or the folder that
contains the specified document if not.
Output: The URI representing the selected directory tree.

ACTION_SCREEN_OFF
public static final String ACTION_SCREEN_OFF
Broadcast Action: Sent when the device goes to sleep and becomes non-interactive.
For historical reasons, the name of this broadcast action refers to the power state of the screen but it is actually sent in response to changes in the overall interactive state of the device.
This broadcast is sent when the device becomes non-interactive which may have
nothing to do with the screen turning off. To determine the
actual state of the screen, use Display.getState()
.
See PowerManager.isInteractive()
for details.

ACTION_SEND
public static final String ACTION_SEND
Activity Action: Deliver some data to someone else. Who the data is being delivered to is not specified; it is up to the receiver of this action to ask the user where the data should be sent.
When launching a SEND intent, you should usually wrap it in a chooser
(through createChooser(Intent, CharSequence)
), which will give the proper interface
for the user to pick how to send your data and allow you to specify
a prompt indicating what they are doing.
Input: getType()
is the MIME type of the data being sent.
get*Extra can have either a EXTRA_TEXT
or EXTRA_STREAM
field, containing the data to be sent. If
using EXTRA_TEXT, the MIME type should be "text/plain"; otherwise it
should be the MIME type of the data in EXTRA_STREAM. Use */*
if the MIME type is unknown (this will only allow senders that can
handle generic data streams). If using EXTRA_TEXT
, you can
also optionally supply EXTRA_HTML_TEXT
for clients to retrieve
your text with HTML formatting.
As of Build.VERSION_CODES.JELLY_BEAN
, the data
being sent can be supplied through setClipData(android.content.ClipData)
. This
allows you to use FLAG_GRANT_READ_URI_PERMISSION
when sharing
content: URIs and other advanced features of ClipData
. If
using this approach, you still must supply the same data through the
EXTRA_TEXT
or EXTRA_STREAM
fields described below
for compatibility with old applications. If you don't set a ClipData,
it will be copied there for you when calling Context#startActivity(Intent)
.
Starting from Build.VERSION_CODES.O
, if
CATEGORY_TYPED_OPENABLE
is passed, then the Uris passed in
either EXTRA_STREAM
or via setClipData(android.content.ClipData)
may
be openable only as asset typed files using
ContentResolver#openTypedAssetFileDescriptor(Uri, String, Bundle)
.
Optional standard extras, which may be interpreted by some recipients as
appropriate, are: EXTRA_EMAIL
, EXTRA_CC
,
EXTRA_BCC
, EXTRA_SUBJECT
.
Output: nothing.
Constant Value: "android.intent.action.SEND"
ACTION_SENDTO
public static final String ACTION_SENDTO

, except the data is multiple.
Input: getType()
is the MIME type of the data being sent.
get*ArrayListExtra can have either a EXTRA_TEXT
or EXTRA_STREAM
field, containing the data to be sent. If using
EXTRA_TEXT
, you can also optionally supply EXTRA_HTML_TEXT
for clients to retrieve your text with HTML formatting.
Multiple types are supported, and receivers should handle mixed types whenever possible. The right way for the receiver to check them is to use the content resolver on each URI. The intent sender should try to put the most concrete mime type in the intent type, but it can fall back to <type>/* or */* as needed.
e.g. if you are sending image/jpg and image/jpg, the intent's type can be image/jpg, but if you are sending image/jpg and image/png, then the intent's type should be image/*.
As of Build.VERSION_CODES.JELLY_BEAN
, the data
being sent can be supplied through setClipData(android.content.ClipData)
. This
allows you to use FLAG_GRANT_READ_URI_PERMISSION
when sharing

. If
using this approach, you still must supply the same data through the
EXTRA_TEXT
or EXTRA_STREAM
fields described below

shown behind their UI, rather than watching for this broadcast and
rendering the wallpaper on their own.
Broadcast Action: The current system wallpaper has changed. See
WallpaperManager
for retrieving the new wallpaper.
This should only be used to determine when the wallpaper
has changed to show the new wallpaper to the user. You should certainly

CATEGORY_ACCESSIBILITY_SHORTCUT_TARGET
public static final String CATEGORY_ACCESSIBILITY_SHORTCUT_TARGET
The accessibility shortcut is a global gesture for users with disabilities to trigger an important for them accessibility feature to help developers determine whether they want to make their activity a shortcut target.
An activity of interest to users with accessibility needs may request to be the target of
the accessibility shortcut. It handles intent ACTION_MAIN
with this category,
which will be dispatched by the system when the user activates the shortcut when it is
configured to point at this target.
An activity declared itself to be a target of the shortcut in AndroidManifest.xml. It must also do two things:
-
Specify that it handles the
android.intent.action.MAIN
Intent
with category android.intent.category.ACCESSIBILITY_SHORTCUT_TARGET
.
-
Provide a meta-data entry
android.accessibilityshortcut.target
in the
manifest when declaring the activity.
<activity android:name=".MainActivity" . . . <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.ACCESSIBILITY_SHORTCUT_TARGET" /> </intent-filter> <meta-data android:name="android.accessibilityshortcut.target" android:resource="@xml/accessibilityshortcut" /> </activity>
This is a sample XML file configuring a accessibility shortcut target:
<accessibility-shortcut-target android:description="@string/shortcut_target_description" android:summary="@string/shortcut_target_summary" android:animatedImageDrawable="@drawable/shortcut_target_animated_image" android:htmlDescription="@string/shortcut_target_html_description" android:settingsActivity="com.example.android.shortcut.target.SettingsActivity" />
Both description and summary are necessary. The system will ignore the accessibility shortcut target if they are missing. The animated image and html description are supported to help users understand how to use the shortcut target. The settings activity is a component name that allows the user to modify the settings for this accessibility shortcut target.
Constant Value: "android.intent.category.ACCESSIBILITY_SHORTCUT_TARGET"
CATEGORY_ALTERNATIVE
public static final String CATEGORY_ALTERNATIVE
Set if the activity should be considered as an alternative action to

Supporting this category means that you would like your activity to be displayed in the set of alternative things the user can do, usually as part of the current activity's options menu. You will usually want to include a specific label in the <intent-filter> of this action describing to the user what it does.
The action of IntentFilter with this category is important in that it
describes the specific action the target will perform. This generally
should not be a generic action (such as ACTION_VIEW
, but rather
a specific name such as "com.android.camera.action.CROP. Only one
alternative of any particular action will be shown to the user, so using
a specific action like this makes sure that your alternative will be
displayed while also allowing other applications to provide their own
overrides of that particular action.

Annotations should describe the major components or topics of the content. It is up to
apps initiating ACTION_CHOOSER
to learn and add annotations. Annotations should be
learned in advance, e.g., when creating or saving content, to avoid increasing latency to
start ACTION_CHOOSER
. Names of customized annotations should not contain the colon
character. Performance on customized annotations can suffer, if they are rarely used for
ACTION_CHOOSER
in the past 14 days. Therefore, it is recommended to use the
following annotations when applicable.
- "product" represents that the topic of the content is mainly about products, e.g., health & beauty, and office supplies.
- "emotion" represents that the topic of the content is mainly about emotions, e.g., happy, and sad.
- "person" represents that the topic of the content is mainly about persons, e.g., face, finger, standing, and walking.

An application may choose to provide alternate extras for the case where a user
selects an activity from a predetermined set of target packages. If the activity
the user selects from the chooser belongs to a package with its package name as
a key in this bundle, the corresponding extras for that package will be merged with
the extras already present in the intent at EXTRA_INTENT
. If a replacement
extra has the same key as an extra already present in the intent it will overwrite
the extra from the intent.
Examples:
- An application may offer different
EXTRA_TEXT
to an application when sharing with it viaACTION_SEND
, augmenting a link with additional query parameters for that target. - An application may offer additional metadata for known targets of a given intent to pass along information only relevant to that target such as account or content identifiers already known to that application.

is present in the intent
used to start a ACTION_CHOOSER
activity this extra will be
filled in
to that IntentSender
and sent
when the user selects a target component from the chooser. It is up to the recipient
to send a result to this ResultReceiver to signal that disambiguation is complete
and that the chooser should invoke the user's choice.
The disambiguator should provide a Bundle to the ResultReceiver with an intent
assigned to the key EXTRA_INTENT
. This supplied intent will be used by the chooser
to match and fill in the final Intent or ChooserTarget before starting it.

If set, and the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.
For example, consider a task consisting of the activities: A, B, C, D. If D calls startActivity() with an Intent that resolves to the component of activity B, then C and D will be finished and B receive the given Intent, resulting in the stack now being: A, B.
The currently running instance of activity B in the above example will
either receive the new intent you are starting here in its
onNewIntent() method, or be itself finished and restarted with the
new intent. If it has declared its launch mode to be "multiple" (the
default) and you have not set FLAG_ACTIVITY_SINGLE_TOP
in
the same intent, then it will be finished and re-created; for all other
launch modes or if FLAG_ACTIVITY_SINGLE_TOP
is set then this
Intent will be delivered to the current instance's onNewIntent().
This launch mode can also be used to good effect in conjunction with
FLAG_ACTIVITY_NEW_TASK
: if used to start the root activity
of a task, it will bring any currently running instance of that task
to the foreground, and then clear it to its root state. This is
especially useful, for example, when launching an activity from the
notification manager.
See Tasks and Back Stack for more information about tasks.
Constant Value: 67108864 (0x04000000)
FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET
public static final int FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET
This constant was deprecated
in API level 21.
As of API 21 this performs identically to
FLAG_ACTIVITY_NEW_DOCUMENT
which should be used instead of this.
Constant Value: 524288 (0x00080000)
FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS
public static final int FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS
If set, the new activity is not kept in the list of recently launched activities.
Constant Value: 8388608 (0x00800000)
FLAG_ACTIVITY_FORWARD_RESULT
public static final int FLAG_ACTIVITY_FORWARD_RESULT
If set and this intent is being used to launch a new activity from an
existing one, then the reply target of the existing activity will be
transferred to the new activity. This way, the new activity can call
Activity.setResult(int)
and have that result sent back to
the reply target of the original activity.
Constant Value: 33554432 (0x02000000)
FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY
public static final int FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY
This flag is not normally set by application code, but set for you by the system if this activity is being launched from history.
Constant Value: 1048576 (0x00100000)
FLAG_ACTIVITY_LAUNCH_ADJACENT
public static final int FLAG_ACTIVITY_LAUNCH_ADJACENT
This flag is only used for split-screen multi-window mode. The new activity will be displayed
adjacent to the one launching it. This can only be used in conjunction with
FLAG_ACTIVITY_NEW_TASK
. Also, setting FLAG_ACTIVITY_MULTIPLE_TASK
is
required if you want a new instance of an existing activity to be created.
Constant Value: 4096 (0x00001000)
FLAG_ACTIVITY_MATCH_EXTERNAL
public static final int FLAG_ACTIVITY_MATCH_EXTERNAL
If set in an Intent passed to Context.startActivity()
,
this flag will attempt to launch an instant app if no full app on the device can already
handle the intent.
When attempting to resolve instant apps externally, the following Intent
properties
are supported:
Intent#setAction(String)
Intent#addCategory(String)
Intent#setData(Uri)
Intent#setType(String)
Intent#setPackage(String)
Intent#addFlags(int)
In the case that no instant app can be found, the installer will be launched to notify the user that the intent could not be resolved. On devices that do not support instant apps, the flag will be ignored.
Constant Value: 2048 (0x00000800)
FLAG_ACTIVITY_MULTIPLE_TASK
public static final int FLAG_ACTIVITY_MULTIPLE_TASK
This flag is used to create a new task and launch an activity into it.
This flag is always paired with either FLAG_ACTIVITY_NEW_DOCUMENT
or FLAG_ACTIVITY_NEW_TASK
. In both cases these flags alone would
search through existing tasks for ones matching this Intent. Only if no such
task is found would a new task be created. When paired with
FLAG_ACTIVITY_MULTIPLE_TASK both of these behaviors are modified to skip
the search for a matching task and unconditionally start a new task.
When used with FLAG_ACTIVITY_NEW_TASK
do not use this
flag unless you are implementing your own
top-level application launcher. Used in conjunction with
FLAG_ACTIVITY_NEW_TASK
to disable the
behavior of bringing an existing task to the foreground. When set,
a new task is always started to host the Activity for the
Intent, regardless of whether there is already an existing task running
the same thing.
Because the default system does not include graphical task management,
you should not use this flag unless you provide some way for a user to
return back to the tasks you have launched.
See FLAG_ACTIVITY_NEW_DOCUMENT
for details of this flag's use for
creating new document tasks.
This flag is ignored if one of FLAG_ACTIVITY_NEW_TASK
or
FLAG_ACTIVITY_NEW_DOCUMENT
is not also set.
See Tasks and Back Stack for more information about tasks.
Constant Value: 134217728 (0x08000000)
FLAG_ACTIVITY_NEW_DOCUMENT
public static final int FLAG_ACTIVITY_NEW_DOCUMENT
This flag is used to open a document into a new task rooted at the activity launched
by this Intent. Through the use of this flag, or its equivalent attribute,
R.attr.documentLaunchMode
multiple instances of the same activity
containing different documents will appear in the recent tasks list.
The use of the activity attribute form of this,
R.attr.documentLaunchMode
, is
preferred over the Intent flag described here. The attribute form allows the
Activity to specify multiple document behavior for all launchers of the Activity
whereas using this flag requires each Intent that launches the Activity to specify it.
Note that the default semantics of this flag w.r.t. whether the recents entry for
it is kept after the activity is finished is different than the use of
FLAG_ACTIVITY_NEW_TASK
and R.attr.documentLaunchMode
-- if
this flag is being used to create a new recents entry, then by default that entry
will be removed once the activity is finished. You can modify this behavior with
FLAG_ACTIVITY_RETAIN_IN_RECENTS
.
FLAG_ACTIVITY_NEW_DOCUMENT may be used in conjunction with FLAG_ACTIVITY_MULTIPLE_TASK
. When used alone it is the
equivalent of the Activity manifest specifying R.attr.documentLaunchMode
="intoExisting". When used with
FLAG_ACTIVITY_MULTIPLE_TASK it is the equivalent of the Activity manifest specifying
R.attr.documentLaunchMode
="always". The flag is ignored even in
conjunction with FLAG_ACTIVITY_MULTIPLE_TASK
when the Activity manifest specifies
R.attr.documentLaunchMode
="never".
Refer to R.attr.documentLaunchMode
for more information.
Constant Value: 524288 (0x00080000)
FLAG_ACTIVITY_NEW_TASK
public static final int FLAG_ACTIVITY_NEW_TASK
If set, this activity will become the start of a new task on this history stack. A task (from the activity that started it to the next task activity) defines an atomic group of activities that the user can move to. Tasks can be moved to the foreground and background; all of the activities inside of a particular task always remain in the same order. See Tasks and Back Stack for more information about tasks.
This flag is generally used by activities that want to present a "launcher" style behavior: they give the user a list of separate things that can be done, which otherwise run completely independently of the activity launching them.
When using this flag, if a task is already running for the activity
you are now starting, then a new activity will not be started; instead,
the current task will simply be brought to the front of the screen with
the state it was last in. See FLAG_ACTIVITY_MULTIPLE_TASK
for a flag
to disable this behavior.
This flag can not be used when the caller is requesting a result from the activity being launched.
Constant Value: 268435456 (0x10000000)
FLAG_ACTIVITY_NO_ANIMATION
public static final int FLAG_ACTIVITY_NO_ANIMATION
If set in an Intent passed to Context.startActivity()
,
this flag will prevent the system from applying an activity transition
animation to go to the next activity state. This doesn't mean an
animation will never run -- if another activity change happens that doesn't
specify this flag before the activity started here is displayed, then
that transition will be used. This flag can be put to good use
when you are going to do a series of activity operations but the
animation seen by the user shouldn't be driven by the first activity
change but rather a later one.
Constant Value: 65536 (0x00010000)
FLAG_ACTIVITY_NO_HISTORY
public static final int FLAG_ACTIVITY_NO_HISTORY
If set, the new activity is not kept in the history stack. As soon as
the user navigates away from it, the activity is finished. This may also
be set with the noHistory
attribute.
If set, onActivityResult()
is never invoked when the current activity starts a new activity which
sets a result and finishes.
Constant Value: 1073741824 (0x40000000)
FLAG_ACTIVITY_NO_USER_ACTION
public static final int FLAG_ACTIVITY_NO_USER_ACTION
If set, this flag will prevent the normal Activity.onUserLeaveHint()
callback from occurring on the current frontmost activity before it is
paused as the newly-started activity is brought to the front.
Typically, an activity can rely on that callback to indicate that an explicit user action has caused their activity to be moved out of the foreground. The callback marks an appropriate point in the activity's lifecycle for it to dismiss any notifications that it intends to display "until the user has seen them," such as a blinking LED.
If an activity is ever started via any non-user-driven events such as
phone-call receipt or an alarm handler, this flag should be passed to Context.startActivity
, ensuring that the pausing
activity does not think the user has acknowledged its notification.
Constant Value: 262144 (0x00040000)
FLAG_ACTIVITY_PREVIOUS_IS_TOP
public static final int FLAG_ACTIVITY_PREVIOUS_IS_TOP
If set and this intent is being used to launch a new activity from an existing one, the current activity will not be counted as the top activity for deciding whether the new intent should be delivered to the top instead of starting a new one. The previous activity will be used as the top, with the assumption being that the current activity will finish itself immediately.
Constant Value: 16777216 (0x01000000)
FLAG_ACTIVITY_REORDER_TO_FRONT
public static final int FLAG_ACTIVITY_REORDER_TO_FRONT
If set in an Intent passed to Context.startActivity()
,
this flag will cause the launched activity to be brought to the front of its
task's history stack if it is already running.
For example, consider a task consisting of four activities: A, B, C, D.
If D calls startActivity() with an Intent that resolves to the component
of activity B, then B will be brought to the front of the history stack,
with this resulting order: A, C, D, B.
This flag will be ignored if FLAG_ACTIVITY_CLEAR_TOP
is also
specified.
Constant Value: 131072 (0x00020000)
FLAG_ACTIVITY_REQUIRE_DEFAULT
public static final int FLAG_ACTIVITY_REQUIRE_DEFAULT
If set in an intent passed to Context.startActivity()
, this
flag will only launch the intent if it resolves to a single result. If no such result exists
or if the system chooser would otherwise be displayed, an ActivityNotFoundException
will be thrown.
Constant Value: 512 (0x00000200)
FLAG_ACTIVITY_REQUIRE_NON_BROWSER
public static final int FLAG_ACTIVITY_REQUIRE_NON_BROWSER
If set in an intent passed to Context.startActivity()
, this
flag will only launch the intent if it resolves to a result that is not a browser. If no such
result exists, an ActivityNotFoundException
will be thrown.
Constant Value: 1024 (0x00000400)
FLAG_ACTIVITY_RESET_TASK_IF_NEEDED
public static final int FLAG_ACTIVITY_RESET_TASK_IF_NEEDED
If set, and this activity is either being started in a new task or bringing to the top an existing task, then it will be launched as the front door of the task. This will result in the application of any affinities needed to have that task in the proper state (either moving activities to or from it), or simply resetting that task to its initial state if needed.
Constant Value: 2097152 (0x00200000)
FLAG_ACTIVITY_RETAIN_IN_RECENTS
public static final int FLAG_ACTIVITY_RETAIN_IN_RECENTS
By default a document created by FLAG_ACTIVITY_NEW_DOCUMENT
will
have its entry in recent tasks removed when the user closes it (with back
or however else it may finish()). If you would like to instead allow the
document to be kept in recents so that it can be re-launched, you can use
this flag. When set and the task's activity is finished, the recents
entry will remain in the interface for the user to re-launch it, like a
recents entry for a top-level application.
The receiving activity can override this request with
R.attr.autoRemoveFromRecents
or by explcitly calling
Activity.finishAndRemoveTask()
.
Constant Value: 8192 (0x00002000)
FLAG_ACTIVITY_SINGLE_TOP
public static final int FLAG_ACTIVITY_SINGLE_TOP
If set, the activity will not be launched if it is already running at the top of the history stack. See Tasks and Back Stack for more information.
Constant Value: 536870912 (0x20000000)
FLAG_ACTIVITY_TASK_ON_HOME
public static final int FLAG_ACTIVITY_TASK_ON_HOME
If set in an Intent passed to Context.startActivity()
,
this flag will cause a newly launching task to be placed on top of the current
home activity task (if there is one). That is, pressing back from the task
will always return the user to home even if that was not the last activity they
saw. This can only be used in conjunction with FLAG_ACTIVITY_NEW_TASK
.
Constant Value: 16384 (0x00004000)
FLAG_DEBUG_LOG_RESOLUTION
public static final int FLAG_DEBUG_LOG_RESOLUTION
A flag you can enable for debugging: when set, log messages will be printed during the resolution of this intent to show you what has been found to create the final resolved list.
Constant Value: 8 (0x00000008)
FLAG_DIRECT_BOOT_AUTO
public static final int FLAG_DIRECT_BOOT_AUTO
Flag used to automatically match intents based on their Direct Boot awareness and the current user state.
Since the default behavior is to automatically apply the current user state, this is effectively a sentinel value that doesn't change the output of any queries based on its presence or absence.
Instead, this value can be useful in conjunction with
StrictMode.VmPolicy.Builder.detectImplicitDirectBoot()
to detect when a caller is relying on implicit automatic matching,
instead of confirming the explicit behavior they want.
Constant Value: 256 (0x00000100)
FLAG_EXCLUDE_STOPPED_PACKAGES
public static final int FLAG_EXCLUDE_STOPPED_PACKAGES
If set, this intent will not match any components in packages that are currently stopped. If this is not set, then the default behavior is to include such applications in the result.
Constant Value: 16 (0x00000010)
FLAG_FROM_BACKGROUND
public static final int FLAG_FROM_BACKGROUND
Can be set by the caller to indicate that this Intent is coming from a background operation, not from direct user interaction.
Constant Value: 4 (0x00000004)
FLAG_GRANT_PERSISTABLE_URI_PERMISSION
public static final int FLAG_GRANT_PERSISTABLE_URI_PERMISSION
When combined with FLAG_GRANT_READ_URI_PERMISSION
and/or
FLAG_GRANT_WRITE_URI_PERMISSION
, the URI permission grant can be
persisted across device reboots until explicitly revoked with
Context#revokeUriPermission(Uri, int)
. This flag only offers the
grant for possible persisting; the receiving application must call
ContentResolver#takePersistableUriPermission(Uri, int)
to
actually persist.
See also:
Constant Value: 64 (0x00000040)
FLAG_GRANT_PREFIX_URI_PERMISSION
public static final int FLAG_GRANT_PREFIX_URI_PERMISSION
When combined with FLAG_GRANT_READ_URI_PERMISSION
and/or
FLAG_GRANT_WRITE_URI_PERMISSION
, the URI permission grant
applies to any URI that is a prefix match against the original granted
URI. (Without this flag, the URI must match exactly for access to be
granted.) Another URI is considered a prefix match only when scheme,
authority, and all path segments defined by the prefix are an exact
match.
Constant Value: 128 (0x00000080)
FLAG_GRANT_READ_URI_PERMISSION
public static final int FLAG_GRANT_READ_URI_PERMISSION
If set, the recipient of this Intent will be granted permission to perform read operations on the URI in the Intent's data and any URIs specified in its ClipData. When applying to an Intent's ClipData, all URIs as well as recursive traversals through data or other ClipData in Intent items will be granted; only the grant flags of the top-level Intent are used.
Constant Value: 1 (0x00000001)
FLAG_GRANT_WRITE_URI_PERMISSION
public static final int FLAG_GRANT_WRITE_URI_PERMISSION
If set, the recipient of this Intent will be granted permission to perform write operations on the URI in the Intent's data and any URIs specified in its ClipData. When applying to an Intent's ClipData, all URIs as well as recursive traversals through data or other ClipData in Intent items will be granted; only the grant flags of the top-level Intent are used.
Constant Value: 2 (0x00000002)
FLAG_INCLUDE_STOPPED_PACKAGES
public static final int FLAG_INCLUDE_STOPPED_PACKAGES
If set, this intent will always match any components in packages that
are currently
stopped.
This is the default behavior when
FLAG_EXCLUDE_STOPPED_PACKAGES
is not set. If both of these
flags are set, this one wins (it allows overriding of exclude for
places where the framework may automatically set the exclude flag,
such as broadcasts).
Constant Value: 32 (0x00000020)
FLAG_RECEIVER_FOREGROUND
public static final int FLAG_RECEIVER_FOREGROUND
If set, when sending a broadcast the recipient is allowed to run at foreground priority, with a shorter timeout interval. During normal broadcasts the receivers are not automatically hoisted out of the background priority class.
Constant Value: 268435456 (0x10000000)
FLAG_RECEIVER_NO_ABORT
public static final int FLAG_RECEIVER_NO_ABORT
If this is an ordered broadcast, don't allow receivers to abort the broadcast. They can still propagate results through to later receivers, but they can not prevent later receivers from seeing the broadcast.
Constant Value: 134217728 (0x08000000)
FLAG_RECEIVER_REGISTERED_ONLY
public static final int FLAG_RECEIVER_REGISTERED_ONLY
If set, when sending a broadcast only registered receivers will be called -- no BroadcastReceiver components will be launched.
Constant Value: 1073741824 (0x40000000)
FLAG_RECEIVER_REPLACE_PENDING
public static final int FLAG_RECEIVER_REPLACE_PENDING
If set, when sending a broadcast the new broadcast will replace
any existing pending broadcast that matches it. Matching is defined
by Intent.filterEquals
returning
true for the intents of the two broadcasts. When a match is found,
the new broadcast (and receivers associated with it) will replace the
existing one in the pending broadcast list, remaining at the same
position in the list.
This flag is most typically used with sticky broadcasts, which only care about delivering the most recent values of the broadcast to their receivers.
Constant Value: 536870912 (0x20000000)
FLAG_RECEIVER_VISIBLE_TO_INSTANT_APPS
public static final int FLAG_RECEIVER_VISIBLE_TO_INSTANT_APPS
If set, the broadcast will be visible to receivers in Instant Apps. By default Instant Apps will not receive broadcasts. This flag has no effect when used by an Instant App.
Constant Value: 2097152 (0x00200000)
METADATA_DOCK_HOME
public static final String METADATA_DOCK_HOME
Boolean that can be supplied as meta-data with a dock activity, to indicate that the dock should take over the home key when it is active.
Constant Value: "android.dock_home"
URI_ALLOW_UNSAFE
public static final int URI_ALLOW_UNSAFE
Flag for use with toUri(int)
and parseUri(String, int)
: allow parsing
of unsafe information. In particular, the flags FLAG_GRANT_READ_URI_PERMISSION
,
FLAG_GRANT_WRITE_URI_PERMISSION
, FLAG_GRANT_PERSISTABLE_URI_PERMISSION
,
and FLAG_GRANT_PREFIX_URI_PERMISSION
flags can not be set, so that the
generated Intent can not cause unexpected data access to happen.
If you do not trust the source of the URI being parsed, you should still do further
processing to protect yourself from it. In particular, when using it to start an
activity you should usually add in CATEGORY_BROWSABLE
to limit the activities
that can handle it.
Constant Value: 4 (0x00000004)
URI_ANDROID_APP_SCHEME
public static final int URI_ANDROID_APP_SCHEME
Flag for use with toUri(int)
and parseUri(String, int)
: the URI string
always has the "android-app:" scheme. This is a variation of
URI_INTENT_SCHEME
whose format is simpler for the case of an
http/https URI being delivered to a specific package name. The format
is:
android-app://{package_id}[/{scheme}[/{host}[/{path}]]][#Intent;{...}]
In this scheme, only the package_id
is required. If you include a host,
you must also include a scheme; including a path also requires both a host and a scheme.
The final #Intent; fragment can be used without a scheme, host, or path.
Note that this can not be
used with intents that have a setSelector(Intent)
, since the base intent
will always have an explicit package name.
Some examples of how this scheme maps to Intent objects:
URI | Intent | ||||||
---|---|---|---|---|---|---|---|
android-app://com.example.app |
|
||||||
android-app://com.example.app/http/example.com |
|
||||||
android-app://com.example.app/http/example.com/foo?1234 |
|
||||||
android-app://com.example.app/ |
|
||||||
android-app://com.example.app/http/example.com/foo?1234 |
|
||||||
android-app://com.example.app/ |
|
Constant Value: 2 (0x00000002)
URI_INTENT_SCHEME
public static final int URI_INTENT_SCHEME
Flag for use with toUri(int)
and parseUri(String, int)
: the URI string
always has the "intent:" scheme. This syntax can be used when you want
to later disambiguate between URIs that are intended to describe an
Intent vs. all others that should be treated as raw URIs. When used
with parseUri(String, int)
, any other scheme will result in a generic
VIEW action for that raw URI.
Constant Value: 1 (0x00000001)
Fields
Public constructors
Intent
public Intent (String action)
Create an intent with a given action. All other fields (data, type, class) are null. Note that the action must be in a namespace because Intents are used globally in the system -- for example the system VIEW action is android.intent.action.VIEW; an application's custom action would be something like com.google.app.myapp.CUSTOM_ACTION.
Parameters | |
---|---|
action |
String : The Intent action, such as ACTION_VIEW. |
Intent
public Intent (String action, Uri uri)
Create an intent with a given action and for a given data url. Note that the action must be in a namespace because Intents are used globally in the system -- for example the system VIEW action is android.intent.action.VIEW; an application's custom action would be something like com.google.app.myapp.CUSTOM_ACTION.
Note: scheme and host name matching in the Android framework is case-sensitive, unlike the formal RFC. As a result, you should always ensure that you write your Uri with these elements using lower case letters, and normalize any Uris you receive from outside of Android to ensure the scheme and host is lower case.
Parameters | |
---|---|
action |
String : The Intent action, such as ACTION_VIEW. |
uri |
Uri : The Intent data URI. |
Intent
public Intent (Context packageContext, Class<?> cls)
Create an intent for a specific component. All other fields (action, data,
type, class) are null, though they can be modified later with explicit
calls. This provides a convenient way to create an intent that is
intended to execute a hard-coded class name, rather than relying on the
system to find an appropriate class for you; see setComponent(ComponentName)
for more information on the repercussions of this.
Parameters | |
---|---|
packageContext |
Context : A Context of the application package implementing
this class. |
cls |
Class : The component class that is to be used for the intent. |
Intent
public Intent (String action, Uri uri, Context packageContext, Class<?> cls)
Create an intent for a specific component with a specified action and data.
This is equivalent to using Intent(java.lang.String, android.net.Uri)
to
construct the Intent and then calling setClass(Context, Class)
to set its
class.
Note: scheme and host name matching in the Android framework is case-sensitive, unlike the formal RFC. As a result, you should always ensure that you write your Uri with these elements using lower case letters, and normalize any Uris you receive from outside of Android to ensure the scheme and host is lower case.
Parameters | |
---|---|
action |
String : The Intent action, such as ACTION_VIEW. |
uri |
Uri : The Intent data URI. |
packageContext |
Context : A Context of the application package implementing
this class. |
cls |
Class : The component class that is to be used for the intent. |
Public methods
addCategory
public Intent addCategory (String category)
Add a new category to the intent. Categories provide additional detail about the action the intent performs. When resolving an intent, only activities that provide all of the requested categories will be used.
Parameters | |
---|---|
category |
String : The desired category. This can be either one of the
predefined Intent categories, or a custom category in your own
namespace. |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
addFlags
public Intent addFlags (int flags)
Add additional flags to the intent (or with existing flags value).
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls into
a single statement.
This value cannot be null . |
See also:
clone
public Object clone ()
Creates and returns a copy of this object. The precise meaning
of "copy" may depend on the class of the object. The general
intent is that, for any object x
, the expression:
will be true, and that the expression:x.clone() != x
will bex.clone().getClass() == x.getClass()
true
, but these are not absolute requirements.
While it is typically the case that:
will bex.clone().equals(x)
true
, this is not an absolute requirement.
By convention, the returned object should be obtained by calling
super.clone
. If a class and all of its superclasses (except
Object
) obey this convention, it will be the case that
x.clone().getClass() == x.getClass()
.
By convention, the object returned by this method should be independent
of this object (which is being cloned). To achieve this independence,
it may be necessary to modify one or more fields of the object returned
by super.clone
before returning it. Typically, this means
copying any mutable objects that comprise the internal "deep structure"
of the object being cloned and replacing the references to these
objects with references to the copies. If a class contains only
primitive fields or references to immutable objects, then it is usually
the case that no fields in the object returned by super.clone
need to be modified.
Returns | |
---|---|
Object |
a clone of this instance. |
cloneFilter
public Intent cloneFilter ()
Make a clone of only the parts of the Intent that are relevant for filter matching: the action, data, type, component, and categories.
Returns | |
---|---|
Intent |
This value cannot be null . |
createChooser
public static Intent createChooser (Intent target, CharSequence title, IntentSender sender)
Convenience function for creating a ACTION_CHOOSER
Intent.
Builds a new ACTION_CHOOSER
Intent that wraps the given
target intent, also optionally supplying a title. If the target
intent has specified FLAG_GRANT_READ_URI_PERMISSION
or
FLAG_GRANT_WRITE_URI_PERMISSION
, then these flags will also be
set in the returned chooser intent, with its ClipData set appropriately:
either a direct reflection of getClipData()
if that is non-null,
or a new ClipData built from getData()
.
The caller may optionally supply an IntentSender
to receive a callback
when the user makes a choice. This can be useful if the calling application wants
to remember the last chosen target and surface it as a more prominent or one-touch
affordance elsewhere in the UI for next time.
Parameters | |
---|---|
target |
Intent : The Intent that the user will be selecting an activity
to perform. |
title |
CharSequence : Optional title that will be displayed in the chooser,
only when the target action is not ACTION_SEND or ACTION_SEND_MULTIPLE. |
sender |
IntentSender : Optional IntentSender to be called when a choice is made. |
Returns | |
---|---|
Intent |
Return a new Intent object that you can hand to
Context.startActivity() and
related methods. |
createChooser
public static Intent createChooser (Intent target, CharSequence title)
Convenience function for creating a ACTION_CHOOSER
Intent.
Builds a new ACTION_CHOOSER
Intent that wraps the given
target intent, also optionally supplying a title. If the target
intent has specified FLAG_GRANT_READ_URI_PERMISSION
or
FLAG_GRANT_WRITE_URI_PERMISSION
, then these flags will also be
set in the returned chooser intent, with its ClipData set appropriately:
either a direct reflection of getClipData()
if that is non-null,
or a new ClipData built from getData()
.
Parameters | |
---|---|
target |
Intent : The Intent that the user will be selecting an activity
to perform. |
title |
CharSequence : Optional title that will be displayed in the chooser,
only when the target action is not ACTION_SEND or ACTION_SEND_MULTIPLE. |
Returns | |
---|---|
Intent |
Return a new Intent object that you can hand to
Context.startActivity() and
related methods. |
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
fillIn
public int fillIn (Intent other, int flags)
Copy the contents of other in to this object, but only where fields are not defined by this object. For purposes of a field being defined, the following pieces of data in the Intent are considered to be separate fields:
- action, as set by
setAction(String)
. - data Uri and MIME type, as set by
setData(android.net.Uri)
,setType(java.lang.String)
, orsetDataAndType(android.net.Uri, java.lang.String)
. - identifier, as set by
setIdentifier(String)
. - categories, as set by
addCategory(String)
. - package, as set by
setPackage(String)
. - component, as set by
setComponent(android.content.ComponentName)
or related methods. - source bounds, as set by
setSourceBounds(Rect)
. - selector, as set by
setSelector(android.content.Intent)
. - clip data, as set by
setClipData(android.content.ClipData)
. - each top-level name in the associated extras.
In addition, you can use the FILL_IN_ACTION
,
FILL_IN_DATA
, FILL_IN_IDENTIFIER
, FILL_IN_CATEGORIES
,
FILL_IN_PACKAGE
, FILL_IN_COMPONENT
, FILL_IN_SOURCE_BOUNDS
,
FILL_IN_SELECTOR
, and FILL_IN_CLIP_DATA
to override
the restriction where the corresponding field will not be replaced if
it is already set.
Note: The component field will only be copied if FILL_IN_COMPONENT
is explicitly specified. The selector will only be copied if
FILL_IN_SELECTOR
is explicitly specified.
For example, consider Intent A with {data="foo", categories="bar"} and Intent B with {action="gotit", data-type="some/thing", categories="one","two"}.
Calling A.fillIn(B, Intent.FILL_IN_DATA) will result in A now containing: {action="gotit", data-type="some/thing", categories="bar"}.
Parameters | |
---|---|
other |
Intent : Another Intent whose values are to be used to fill in
the current one.
This value cannot be null . |
flags |

filterEquals
public boolean filterEquals (Intent other)
Determine if two intents are the same for the purposes of intent
resolution (filtering). That is, if their action, data, type, identity,

makeMainActivity
public static Intent makeMainActivity (ComponentName mainActivity)
Create an intent to launch the main (root) activity of a task. This is the Intent that is started when the application's is launched from Home. For anything else that wants to launch an application in the same way, it is important that they use an Intent structured the same way, and can use this function to ensure this is the case.
The returned Intent has the given Activity component as its explicit
component, ACTION_MAIN
as its action, and includes the
category CATEGORY_LAUNCHER
. This does not have
FLAG_ACTIVITY_NEW_TASK
set, though typically you will want
to do that through addFlags(int)
on the returned Intent.
Parameters | |

mainActivity |
ComponentName : The main activity component that this Intent will
launch. |
Returns | |
---|---|
Intent |
Returns a newly created Intent that can be used to launch the activity as a main application entry. |
makeMainSelectorActivity
public static Intent makeMainSelectorActivity (String selectorAction, String selectorCategory)
Make an Intent for the main activity of an application, without specifying a specific activity to run but giving a selector to find the activity. This results in a final Intent that is structured the same as when the application is launched from Home. For anything else that wants to launch an application in the same way, it is important that they use an Intent structured the same way, and can use this function to ensure this is the case.
The returned Intent has ACTION_MAIN
as its action, and includes the
category CATEGORY_LAUNCHER
. This does not have
FLAG_ACTIVITY_NEW_TASK
set, though typically you will want
to do that through addFlags(int)
on the returned Intent.
Parameters | |

selectorAction |
String : The action name of the Intent's selector. |
selectorCategory |
String : The name of a category to add to the Intent's
selector. |
Returns | |

Returns a newly created Intent that can be used to relaunch the activity's task in its root state. |
normalizeMimeType
public static String normalizeMimeType (String type)
Normalize a MIME data type.

For example, "text/plain; charset=utf-8" becomes "text/plain". "text/x-vCard" becomes "text/x-vcard".
All MIME types received from outside Android (such as user input, or external sources like Bluetooth, NFC, or the Internet) should be normalized before they are used to create an Intent.
Parameters | |
---|---|
type |
String : MIME data type to normalize
This value may be null . |
Returns | |
---|---|
String |
normalized MIME data type, or null if the input was null |
parseIntent

resolveActivity
public ComponentName resolveActivity (PackageManager pm)
Return the Activity component that should be used to handle this intent. The appropriate component is determined based on the information in the intent, evaluated as follows:
If getComponent()
returns an explicit class, that is returned
without any further consideration.
The activity must handle the Intent#CATEGORY_DEFAULT
Intent
category to be considered.
If getAction()
is non-NULL, the activity must handle this
action.
If resolveType(ContentResolver)
returns non-NULL, the activity must handle
this type.
If addCategory(String)
has added any categories, the activity must
handle ALL of the categories specified.
If getPackage()
is non-NULL, only activity components in
that application package will be considered.
If there are no activities that satisfy all of these conditions, a null string is returned.
If multiple activities are found to satisfy the intent, the one with the highest priority will be used. If there are multiple activities with the same priority, the system will either pick the best activity based on user preference, or resolve to a system class that will allow the user to pick an activity and forward from there.
This method is implemented simply by calling
PackageManager#resolveActivity
with the "defaultOnly" parameter
true.
This API is called for you as part of starting an activity from an intent. You do not normally need to call it yourself.
Parameters | |
---|---|
pm |
PackageManager : The package manager with which to resolve the Intent.
This value cannot be null . |
Returns | |
---|---|
ComponentName |
Name of the component implementing an activity that can display the intent. |
resolveActivityInfo
public ActivityInfo resolveActivityInfo (PackageManager pm, int flags)
Resolve the Intent into an ActivityInfo
describing the activity that should execute the intent. Resolution
follows the same rules as described for resolveActivity(PackageManager)
, but
you get back the completely information about the resolved activity
instead of just its class name.
Returns | |
---|---|
ActivityInfo |
PackageManager.ActivityInfo |

setClipData
public void setClipData (ClipData clip)
Set a ClipData
associated with this Intent. This replaces any
previously set ClipData.
The ClipData in an intent is not used for Intent matching or other
such operations. Semantically it is like extras, used to transmit
additional data with the Intent. The main feature of using this over
the extras for data is that FLAG_GRANT_READ_URI_PERMISSION
and FLAG_GRANT_WRITE_URI_PERMISSION
will operate on any URI
items included in the clip data. This is useful, in particular, if
you want to transmit an Intent containing multiple content:
URIs for which the recipient may not have global permission to access the
content provider.
If the ClipData contains items that are themselves Intents, any grant flags in those Intents will be ignored. Only the top-level flags of the main Intent are respected, and will be applied to all Uri or Intent items in the clip (or sub-items of the clip).
The MIME type, label, and icon in the ClipData object are not directly used by Intent. Applications should generally rely on the MIME type of the Intent itself, not what it may find in the ClipData. A common practice is to construct a ClipData for use with an Intent with a MIME type of "*/*".
Parameters | |
---|---|
clip |
ClipData : The new clip to set. May be null to clear the current clip. |
setComponent
public Intent setComponent (ComponentName component)
(Usually optional) Explicitly set the component to handle the intent. If left with the default value of null, the system will determine the appropriate class to use based on the other fields (action, data, type, categories) in the Intent. If this class is defined, the specified class will always be used regardless of the other fields. You should only set this value when you know you absolutely want a specific class to be used; otherwise it is better to let the system find the appropriate class so that you will respect the installed applications and user preferences.
Parameters | |
---|---|
component |
ComponentName : The name of the application component to handle the
intent, or null to let the system find one for you. |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls into a single statement. |
setData
public Intent setData (Uri data)
Set the data this intent is operating on. This method automatically
clears any type that was previously set by setType(String)
or
setTypeAndNormalize(String)
.
Note: scheme matching in the Android framework is
case-sensitive, unlike the formal RFC. As a result,
you should always write your Uri with a lower case scheme,
or use Uri#normalizeScheme
or
setDataAndNormalize(Uri)
to ensure that the scheme is converted to lower case.
Parameters | |
---|---|
data |
Uri : The Uri of the data this intent is now targeting.
This value may be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
setDataAndNormalize
public Intent setDataAndNormalize (Uri data)
Normalize and set the data this intent is operating on.
This method automatically clears any type that was
previously set (for example, by setType(String)
).
The data Uri is normalized using
Uri.normalizeScheme()
before it is set,
so really this is just a convenience method for
setData(data.normalize())
Parameters | |
---|---|
data |
Uri : The Uri of the data this intent is now targeting.
This value cannot be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
setDataAndType
public Intent setDataAndType (Uri data, String type)
(Usually optional) Set the data for the intent along with an explicit MIME data type. This method should very rarely be used -- it allows you to override the MIME type that would ordinarily be inferred from the data with your own type given here.
Note: MIME type and Uri scheme matching in the
Android framework is case-sensitive, unlike the formal RFC definitions.
As a result, you should always write these elements with lower case letters,
or use normalizeMimeType(String)
or Uri.normalizeScheme()
or
setDataAndTypeAndNormalize(Uri, String)
to ensure that they are converted to lower case.
Parameters | |
---|---|
data |
Uri : The Uri of the data this intent is now targeting.
This value may be null . |
type |
String : The MIME type of the data being handled by this intent.
This value may be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
setDataAndTypeAndNormalize
public Intent setDataAndTypeAndNormalize (Uri data, String type)
(Usually optional) Normalize and set both the data Uri and an explicit MIME data type. This method should very rarely be used -- it allows you to override the MIME type that would ordinarily be inferred from the data with your own type given here.
The data Uri and the MIME type are normalize using
Uri.normalizeScheme()
and normalizeMimeType(String)
before they are set, so really this is just a convenience method for
setDataAndType(data.normalize(), Intent.normalizeMimeType(type))
Parameters | |
---|---|
data |
Uri : The Uri of the data this intent is now targeting.
This value cannot be null . |
type |
String : The MIME type of the data being handled by this intent.
This value may be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
setExtrasClassLoader
public void setExtrasClassLoader (ClassLoader loader)
Sets the ClassLoader that will be used when unmarshalling any Parcelable values from the extras of this Intent.
Parameters | |
---|---|
loader |
ClassLoader : a ClassLoader, or null to use the default loader
at the time of unmarshalling. |
setFlags
public Intent setFlags (int flags)
Set special flags controlling how this intent is handled. Most values
here depend on the type of component being executed by the Intent,
specifically the FLAG_ACTIVITY_* flags are all for use with
Context.startActivity()
and the
FLAG_RECEIVER_* flags are all for use with
Context.sendBroadcast()
.
See the Tasks and Back Stack documentation for important information on how some of these options impact the behavior of your application.
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
See also:
setIdentifier
public Intent setIdentifier (String identifier)
Set an identifier for this Intent. If set, this provides a unique identity for this Intent,
allowing it to be unique from other Intents that would otherwise look the same. In
particular, this will be used by filterEquals(android.content.Intent)
to determine if two
Intents are the same as with other fields like setAction(String)
. However, unlike those
fields, the identifier is never used for matching against an IntentFilter
;
it is as if the identifier has not been set on the Intent.
This can be used, for example, to make this Intent unique from other Intents that
are otherwise the same, for use in creating a PendingIntent
. (Be aware
however that the receiver of the PendingIntent will see whatever you put in here.) The
structure of this string is completely undefined by the platform, however if you are going
to be exposing identifier strings across different applications you may need to define
your own structure if there is no central party defining the contents of this field.
Parameters | |
---|---|
identifier |
String : The identifier for this Intent. The contents of the string have no
meaning to the system, except whether they are exactly the same as
another identifier.
This value may be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
See also:
setPackage
public Intent setPackage (String packageName)
(Usually optional) Set an explicit application package name that limits the components this Intent will resolve to. If left to the default value of null, all components in all applications will considered. If non-null, the Intent can only match the components in the given application package.
Parameters | |
---|---|
packageName |
String : The name of the application package to handle the
intent, or null to allow any application package. |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls into a single statement. |
setSelector
public void setSelector (Intent selector)
Set a selector for this Intent. This is a modification to the kinds of things the Intent will match. If the selector is set, it will be used when trying to find entities that can handle the Intent, instead of the main contents of the Intent. This allows you build an Intent containing a generic protocol while targeting it more specifically.
An example of where this may be used is with things like
CATEGORY_APP_BROWSER
. This category allows you to build an
Intent that will launch the Browser application. However, the correct
main entry point of an application is actually ACTION_MAIN
CATEGORY_LAUNCHER
with setComponent(android.content.ComponentName)
used to specify the actual Activity to launch. If you launch the browser
with something different, undesired behavior may happen if the user has
previously or later launches it the normal way, since they do not match.
Instead, you can build an Intent with the MAIN action (but no ComponentName
yet specified) and set a selector with ACTION_MAIN
and
CATEGORY_APP_BROWSER
to point it specifically to the browser activity.
Setting a selector does not impact the behavior of
filterEquals(android.content.Intent)
and filterHashCode()
. This is part of the
desired behavior of a selector -- it does not impact the base meaning
of the Intent, just what kinds of things will be matched against it
when determining who can handle it.
You can not use both a selector and setPackage(java.lang.String)
on
the same base Intent.
Parameters | |
---|---|
selector |
Intent : The desired selector Intent; set to null to not use
a special selector. |
setSourceBounds
public void setSourceBounds (Rect r)
Set the bounds of the sender of this intent, in screen coordinates. This can be used as a hint to the receiver for animations and the like. Null means that there is no source bounds.
Parameters | |
---|---|
r |
Rect : This value may be null . |
setType
public Intent setType (String type)
Set an explicit MIME data type.
This is used to create intents that only specify a type and not data, for example to indicate the type of data to return.
This method automatically clears any data that was
previously set (for example by setData(Uri)
).
Note: MIME type matching in the Android framework is
case-sensitive, unlike formal RFC MIME types. As a result,
you should always write your MIME types with lower case letters,
or use normalizeMimeType(String)
or setTypeAndNormalize(String)
to ensure that it is converted to lower case.
Parameters | |
---|---|
type |
String : The MIME type of the data being handled by this intent.
This value may be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
setTypeAndNormalize
public Intent setTypeAndNormalize (String type)
Normalize and set an explicit MIME data type.
This is used to create intents that only specify a type and not data, for example to indicate the type of data to return.
This method automatically clears any data that was
previously set (for example by setData(Uri)
).
The MIME type is normalized using
normalizeMimeType(String)
before it is set,
so really this is just a convenience method for
setType(Intent.normalizeMimeType(type))
Parameters | |
---|---|
type |
String : The MIME type of the data being handled by this intent.
This value may be null . |
Returns | |
---|---|
Intent |
Returns the same Intent object, for chaining multiple calls
into a single statement.
This value cannot be null . |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
toURI
public String toURI ()
This method was deprecated
in API level 15.
Use toUri(int)
instead.
Call toUri(int)
with 0 flags.
Returns | |
---|---|
String |
toUri
public String toUri (int flags)
Convert this Intent into a String holding a URI representation of it.
The returned URI string has been properly URI encoded, so it can be
used with Uri.parse(String)
. The URI contains the
Intent's data as the base URI, with an additional fragment describing
the action, categories, type, flags, package, component, and extras.
You can convert the returned string back to an Intent with
getIntent(String)
.
Parameters | |
---|---|
flags |
int : Additional operating flags.
Value is either 0 or a combination of URI_ALLOW_UNSAFE , URI_ANDROID_APP_SCHEME , and URI_INTENT_SCHEME |
Returns | |
---|---|
String |
Returns a URI encoding URI string describing the entire contents of the Intent. |
writeToParcel
public void writeToParcel (Parcel out, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
out |
Parcel : The Parcel in which the object should be written.
This value cannot be null . |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
