Finishing an Activity from a Broadcast Receiver
Please observe the scenario I have:
Class A extends Activity
Class B extends BroadcastReceiver
How can I finish Activity A from Class B's onReceive method? Any help is much appreciated.
回答1:
The best way to deal with this is to register a broadcast receiver in code inside your activity and listen for that particular broadcast message for which you want to finish your activity.
P.S. Independent Broadcast-Receivers and Services don't have right to manipulate Activities, except for launching Activities as new task.
