LauncherApps

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. 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: ACTION_MANAGED_PROFILE_ADDED and ACTION_MANAGED_PROFILE_REMOVED.

You can retrieve the list of profiles associated with this user with getUserProfiles().

getShortcutIconDrawable

Added in API level 25

Drawable getShortcutIconDrawable (ShortcutInfo shortcut, 
                int density)

Returns the icon for this shortcut, without any badging for the profile.

The calling launcher application must be allowed to access the shortcut information, as defined in hasShortcutHostPermission().

`shortcut`	`ShortcutInfo`
`density`	`int`: The preferred density of the icon, zero for default density. Use density DPI values from `DisplayMetrics`.

See also:

getShortcuts

Added in API level 25

List<ShortcutInfo> getShortcuts (LauncherApps.ShortcutQuery query, 
                UserHandle user)

Returns ShortcutInfos that match query.

Callers must be allowed to access the shortcut information, as defined in hasShortcutHostPermission().

Parameters
`query`	`LauncherApps.ShortcutQuery`: result includes shortcuts matching this query.
`user`	`UserHandle`: The UserHandle of the profile.

hasShortcutHostPermission

Added in API level 25

boolean hasShortcutHostPermission ()

Returns whether the caller can access the shortcut information.

Only the default launcher can access the shortcut information.

Note when this method returns false, it may be a temporary situation because the user is trying a new launcher application. 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.

isActivityEnabled

Added in API level 21

boolean isActivityEnabled (ComponentName component,

isPackageEnabled

Added in API level 21

boolean isPackageEnabled (String packageName, 
                UserHandle user)

Checks if the package is installed and enabled for a profile.

`user`	`UserHandle`: The UserHandle of the profile.

Returns
`boolean`	true if the package exists and is enabled.
