public class LauncherApps
extends Object

java.lang.Object
↳	android.content.pm.LauncherApps

---

Class for retrieving a list of launchable activities for the current user and any associated managed profiles that are visible to the current user, which can be retrieved with getProfiles(). This is mainly for use by launchers. Apps can be queried for each user profile. Since the PackageManager will not deliver package broadcasts for other profiles, you can register for package changes here.

To watch for managed profiles being added or removed, register for the following broadcasts: Intent.ACTION_MANAGED_PROFILE_ADDED and Intent.ACTION_MANAGED_PROFILE_REMOVED.

Note as of Android O, apps on a managed profile are no longer allowed to access apps on the main profile. Apps can only access profiles returned by getProfiles().

Constants

ACTION_CONFIRM_PIN_APPWIDGET

Added in API level 26

public static final String ACTION_CONFIRM_PIN_APPWIDGET

Activity Action: For the default launcher to show the confirmation dialog to create a pinned app widget.

See the AppWidgetManager.requestPinAppWidget(ComponentName, Bundle, PendingIntent) javadoc for details.

Use getPinItemRequest(android.content.Intent) to get a PinItemRequest object, and call PinItemRequest.accept(Bundle) if the user accepts. If the user doesn't accept, no further action is required.

See also:

• EXTRA_PIN_ITEM_REQUEST

Constant Value: "android.content.pm.action.CONFIRM_PIN_APPWIDGET"

ACTION_CONFIRM_PIN_SHORTCUT

Added in API level 26

public static final String ACTION_CONFIRM_PIN_SHORTCUT

Activity Action: For the default launcher to show the confirmation dialog to create a pinned shortcut.

See the ShortcutManager javadoc for details.

Use getPinItemRequest(android.content.Intent) to get a PinItemRequest object, and call PinItemRequest.accept(Bundle) if the user accepts. If the user doesn't accept, no further action is required.

See also:

• EXTRA_PIN_ITEM_REQUEST

Constant Value: "android.content.pm.action.CONFIRM_PIN_SHORTCUT"

EXTRA_PIN_ITEM_REQUEST

Added in API level 26

public static final String EXTRA_PIN_ITEM_REQUEST

An extra for ACTION_CONFIRM_PIN_SHORTCUT & ACTION_CONFIRM_PIN_APPWIDGET containing a PinItemRequest of appropriate type asked to pin.

A helper function getPinItemRequest(android.content.Intent) can be used instead of using this constant directly.

See also:

• ACTION_CONFIRM_PIN_SHORTCUT
• ACTION_CONFIRM_PIN_APPWIDGET

Constant Value: "android.content.pm.extra.PIN_ITEM_REQUEST"

Public methods

getActivityList

Added in API level 21

public List<LauncherActivityInfo> getActivityList (String packageName, 
                UserHandle user)

Retrieves a list of activities that specify Intent.ACTION_MAIN and Intent.CATEGORY_LAUNCHER, across all apps, for a specified user. If an app doesn't have any activities that specify ACTION_MAIN or CATEGORY_LAUNCHER, the system adds a synthesized activity to the list. This synthesized activity represents the app's details page within system settings.

Note: It's possible for system apps, such as app stores, to prevent the system from adding synthesized activities to the returned list.

As of Android Q, at least one of the app's activities or synthesized activities appears in the returned list unless the app satisfies at least one of the following conditions:

• The app is a system app.
• The app doesn't request any permissions.
• The app doesn't have a launcher activity that is enabled by default. A launcher activity has an intent containing the ACTION_MAIN action and the CATEGORY_LAUNCHER category.

Additionally, the system hides synthesized activities for some or all apps in the following enterprise-related cases:

• If the device is a fully managed device, no synthesized activities for any app appear in the returned list.
• If the current user has a work profile, no synthesized activities for the user's work apps appear in the returned list.

If the user in question is a hidden profile UserManager.USER_TYPE_PROFILE_PRIVATE, caller should have normal Manifest.permission.ACCESS_HIDDEN_PROFILES permission and the RoleManager.ROLE_HOME role.

Parameters
packageName	String: The specific package to query. If null, it checks all installed packages in the profile.
user	UserHandle: The UserHandle of the profile.

Returns
List<LauncherActivityInfo>	List of launchable activities. Can be an empty list but will not be null.

getAllPackageInstallerSessions

Added in API level 29

public List<PackageInstaller.SessionInfo> getAllPackageInstallerSessions ()

Return list of all known install sessions in this user and managed profiles, regardless of the installer. Callers need to either declare <queries> element with the specific package name in the app's manifest, have the android.permission.QUERY_ALL_PACKAGES, or be the session owner to retrieve these details.

To receive callbacks for hidden profile UserManager.USER_TYPE_PROFILE_PRIVATE, caller should have normal Manifest.permission.ACCESS_HIDDEN_PROFILES permission and the RoleManager.ROLE_HOME role.

Returns
List<PackageInstaller.SessionInfo>	This value cannot be null.

See also:

• PackageInstaller.getAllSessions()

getAppMarketActivityIntent

Added in API level 35

public IntentSender getAppMarketActivityIntent (String packageName, 
                UserHandle user)

Returns an intent sender which can be used to start the App Market activity (Installer Activity). This method is primarily used to get an intent sender which starts App Market activity for another profile, if the caller is not otherwise allowed to start activity in that profile.

When packageName is set, intent sender to start the App Market Activity which installed the package in calling user will be returned, but for the profile passed.

When packageName is not set, intent sender to launch the default App Market Activity for the profile will be returned. In case there are multiple App Market Activities available for the profile, IntentPicker will be started, allowing user to choose the preferred activity.

The method will fall back to the behaviour of not having the packageName set, in case:

• No activity for the packageName is found in calling user-space.
• The App Market Activity which installed the package in calling user-space is not present.
• The App Market Activity which installed the package in calling user-space is not present in the profile passed.

If the user in question is a hidden profile UserManager.USER_TYPE_PROFILE_PRIVATE, caller should have normal Manifest.permission.ACCESS_HIDDEN_PROFILES permission and the RoleManager.ROLE_HOME role.

Parameters
packageName	String: the package for which intent sender to launch App Market Activity is required. This value may be null.
user	UserHandle: the profile for which intent sender to launch App Market Activity is required. This value cannot be null.

Returns
IntentSender	IntentSender object which launches the App Market Activity, null in case there is no such activity.

Gets the launcher extras supplied to the system when the given package was suspended via PackageManager#setPackagesSuspended(String[], boolean, PersistableBundle, PersistableBundle, String).

The contents of this Bundle are supposed to be a contract between the suspending app and the launcher.

If the user in question is a hidden profile UserManager.USER_TYPE_PROFILE_PRIVATE, caller should have normal Manifest.permission.ACCESS_HIDDEN_PROFILES permission and the RoleManager.ROLE_HOME role.

Note: This just returns whatever extras were provided to the system, which might even be null.

The user may decide to change the default launcher back to the calling application again, so even if a launcher application loses this permission, it does not have to purge pinned shortcut information. If the calling launcher application contains pinned shortcuts, they will still work, even though the caller no longer has the shortcut host permission.

Returns
boolean

Throws
IllegalStateException	when the user is locked.
