Public Methods

public void finishAndRemoveTask ()

Added in API level 21

Finishes all activities in this task and removes it from the recent tasks list.

public ActivityManager.RecentTaskInfo getTaskInfo ()

Added in API level 21

Get the RecentTaskInfo associated with this task.

Returns
  • The RecentTaskInfo for this task, or null if the task no longer exists.

public void moveToFront ()

Added in API level 21

Bring this task to the foreground. If it contains activities, they will be brought to the foreground with it and their instances re-created if needed. If it doesn't contain activities, the root activity of the task will be re-launched.

public void setExcludeFromRecents (boolean exclude)

Added in API level 21

Modify the FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS flag in the root Intent of this AppTask.

Parameters
exclude If true, FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS will be set; otherwise, it will be cleared.

public void startActivity (Context context, Intent intent, Bundle options)

Added in API level 21

Start an activity in this task. Brings the task to the foreground. If this task is not currently active (that is, its id < 0), then a new activity for the given Intent will be launched as the root of the task and the task brought to the foreground. Otherwise, if this task is currently active and the Intent does not specify an activity to launch in a new task, then a new activity for the given Intent will be launched on top of the task and the task brought to the foreground. If this task is currently active and the Intent specifies FLAG_ACTIVITY_NEW_TASK or would otherwise be launched in to a new task, then the activity not launched but this task be brought to the foreground and a new intent delivered to the top activity if appropriate.

In other words, you generally want to use an Intent here that does not specify FLAG_ACTIVITY_NEW_TASK or FLAG_ACTIVITY_NEW_DOCUMENT, and let the system do the right thing.

Parameters
intent The Intent describing the new activity to be launched on the task.
options Optional launch options.
