LabeledIntent

LabeledIntent A special subclass of Intent that can have a custom label/icon associated with it.

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, while CATEGORY_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 category CATEGORY_HOME -- Launch the home screen.
ACTION_GET_CONTENT with MIME type vnd.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 category CATEGORY_OPENABLE -- Display all pickers for data that can be opened with ContentResolver.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) or setClass(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 as http: or mailto:) 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 and CATEGORY_ALTERNATIVE, then you will only resolve to components with an intent that lists both of those categories. Activities will very often need to support the CATEGORY_DEFAULT so that they can be found by Context.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.

             </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 the Context.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}.

Standard Activity Actions

These are the current standard actions that Intent defines for launching activities (usually through Context.startActivity. The most important, and by far most frequently used, are ACTION_MAIN and ACTION_EDIT.

Standard Broadcast Actions

These are the current standard actions that Intent defines for receiving broadcasts (usually through Context.registerReceiver or a <receiver> tag in a manifest).

Note: If your app targets Android 11 (API level 30) or higher, registering broadcast such as ACTION_PACKAGES_SUSPENDED that includes package details in the extras receives a filtered list of apps or nothing. Learn more about how to manage package visibility.

Standard Categories

These are the current standard categories that can be used to further clarify an Intent via addCategory(String).

Standard Extra Data

These are the current standard fields that can be used as extra data via putExtra(String, Bundle).

Flags

These are the possible flags that can be used in the Intent via setFlags(int) and addFlags(int). See setFlags(int) for a list of all possible flags.

ACTION_BATTERY_CHANGED

Added in API level 1

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, ACTION_BATTERY_OKAY, ACTION_POWER_CONNECTED, and ACTION_POWER_DISCONNECTED for distinct battery-related broadcasts that are sent and can be received through manifest receivers.

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.BATTERY_CHANGED"

ACTION_BATTERY_LOW

Added in API level 1

public static final String ACTION_BATTERY_LOW

Broadcast Action: Indicates low battery condition on the device. This broadcast corresponds to the "Low battery warning" system dialog.

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.BATTERY_LOW"

ACTION_BATTERY_OKAY

Added in API level 4

public static final String ACTION_BATTERY_OKAY

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.BATTERY_OKAY"

ACTION_BOOT_COMPLETED

Added in API level 1

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.

Starting from Android Build.VERSION_CODES.VANILLA_ICE_CREAM, this broadcast is not only sent after the device boots but also delivered to an app when it is removed from the Stopped state and the user is unlocked, such as the first launch after force-stopping the app. This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.BOOT_COMPLETED"

ACTION_BUG_REPORT

Added in API level 1

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

Added in API level 1

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 your app targets M or higher 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

Added in API level 1

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

Added in API level 1

public static final String ACTION_CAMERA_BUTTON

Constant Value: "android.intent.action.CAMERA_BUTTON"

ACTION_CARRIER_SETUP

Added in API level 26

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

Added in API level 1

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

Added in API level 1
Deprecated in API level 31

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

AccessibilityService.GLOBAL_ACTION_DISMISS_NOTIFICATION_SHADE

Constant Value: "android.intent.action.CLOSE_SYSTEM_DIALOGS"

ACTION_CONFIGURATION_CHANGED

Added in API level 1

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.

Configuration

Constant Value: "android.intent.action.CONFIGURATION_CHANGED"

ACTION_CREATE_DOCUMENT

Added in API level 19

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.

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

Added in API level 1

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

Added in API level 18

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.

The response should contain an extra 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.

See also:

RestrictionEntry

Constant Value: "android.intent.action.GET_RESTRICTION_ENTRIES"

Input: getType() is the desired MIME type of the item to create or edit. The extras can contain type specific data to pass through to the editing/creating activity.

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.INSERT_OR_EDIT"

ACTION_INSTALL_FAILURE

Added in API level 27

public static final String ACTION_INSTALL_FAILURE

Activity Action: Activity to handle split installation failures.

Splits may be installed dynamically. This happens when an Activity is launched, but the split that contains the application isn't installed. When a split is installed in this manner, the containing package usually doesn't know this is happening. However, if an error occurs during installation, the containing package can define a single activity handling this action to deal with such failures.

The activity handling this action must be in the base package.

Input: EXTRA_INTENT the original intent that started split installation. EXTRA_SPLIT_NAME the name of the split that failed to be installed.

Constant Value: "android.intent.action.INSTALL_FAILURE"

ACTION_INSTALL_PACKAGE

Added in API level 14
Deprecated in API level 29

public static final String ACTION_INSTALL_PACKAGE

This constant was deprecated in API level 29.
use PackageInstaller instead

Activity Action: Launch application installer.

Input: The data must be a content: URI at which the application can be retrieved. As of Build.VERSION_CODES.JELLY_BEAN_MR1, you can also use "package:" to install an application for the current user that is already installed for another user. You can optionally supply EXTRA_INSTALLER_PACKAGE_NAME, EXTRA_NOT_UNKNOWN_SOURCE, EXTRA_ALLOW_REPLACE, and EXTRA_RETURN_RESULT.

Output: If EXTRA_RETURN_RESULT, returns whether the install succeeded.

Note:If your app is targeting API level higher than 25 you need to hold Manifest.permission.REQUEST_INSTALL_PACKAGES in order to launch the application installer.

See also:

Constant Value: "android.intent.action.INSTALL_PACKAGE"

ACTION_LAUNCH_CAPTURE_CONTENT_ACTIVITY_FOR_NOTE

Added in API level 34

public static final String ACTION_LAUNCH_CAPTURE_CONTENT_ACTIVITY_FOR_NOTE

Activity Action: Use with startActivityForResult to start a system activity that captures content on the screen to take a screenshot and present it to the user for editing. The edited screenshot is saved on device and returned to the calling activity as a Uri through getData(). User interaction is required to return the edited screenshot to the calling activity.

The response Intent may include additional data to "backlink" directly back to the application for which the screenshot was captured. If present, the application "backlink" can be retrieved via getClipData(). The data is present only if the user accepted to include the link information with the screenshot. The data can contain one of the following:

A deeplinking Uri or an Intent if the captured app integrates with AssistContent.
Otherwise, a main launcher intent that launches the screenshotted application to its home screen.

The "backlink" to the screenshotted application will be set within ClipData, either as a Uri or an Intent if present.

This intent action requires the permission Manifest.permission.LAUNCH_CAPTURE_CONTENT_ACTIVITY_FOR_NOTE.

Callers should query StatusBarManager.canLaunchCaptureContentActivityForNote(Activity) before showing a UI element that allows users to trigger this flow.

Callers should query for EXTRA_CAPTURE_CONTENT_FOR_NOTE_STATUS_CODE in the response Intent to check if the request was a success.
Requires Manifest.permission.LAUNCH_CAPTURE_CONTENT_ACTIVITY_FOR_NOTE

Constant Value: "android.intent.action.LAUNCH_CAPTURE_CONTENT_ACTIVITY_FOR_NOTE"

ACTION_LOCALE_CHANGED

Added in API level 7

public static final String ACTION_LOCALE_CHANGED

Broadcast Action: The receiver's effective locale has changed. This happens when the device locale, the receiving app's locale (set via LocaleManager.setApplicationLocales(LocaleList)) or language tags of Regional preferences changed. Can be received by manifest-declared receivers.

If only the app locale changed, includes the following extras:

EXTRA_PACKAGE_NAME is the name of the package for which locale changed.
EXTRA_LOCALE_LIST contains locales that are currently set for specified app

This is a protected intent that can only be sent by the system.

Constant Value: "android.intent.action.LOCALE_CHANGED"

ACTION_LOCKED_BOOT_COMPLETED

Added in API level 24

public static final String ACTION_LOCKED_BOOT_COMPLETED

Broadcast Action: This is broadcast once, after the user has finished booting, but while still in the "locked" state. 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 immediately at boot by all devices (regardless of direct boot support) running Build.VERSION_CODES.N or higher. Upon receipt of this broadcast, the user is still locked and only device-protected storage can be accessed safely. If you want to access credential-protected storage, you need to wait for the user to be unlocked (typically by entering their lock pattern or PIN for the first time), after which the ACTION_USER_UNLOCKED and ACTION_BOOT_COMPLETED broadcasts are sent.

To receive this broadcast, your receiver component must be marked as being ComponentInfo.directBootAware.

Starting from Android Build.VERSION_CODES.VANILLA_ICE_CREAM, this broadcast is not only sent after the device boots but also delivered to an app when it is removed from the Stopped state, such as the first launch after force-stopping the app. This is a protected intent that can only be sent by the system.
