Remove notification from notification bar from other applications

Question

I want to remove notifications from another application shown in the notification bar. Is that possible? NotificationManager.cancelAll(); cancels only notificat

Answer 1

You can close any notification use NotificationListenerService:

public class NotificationListener extends NotificationListenerService {

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
      cancelNotification(sbn.getKey());
    }
}

Your application must have BIND_NOTIFICATION_LISTENER_SERVICE permission. https://developer.android.com/reference/android/service/notification/NotificationListenerService.html

Answer 2

You can cancel your own notifications using NotificationManager.
But you can't cancel other apps' notifications, that is not possible.

Answer 3

From Android 4.3 onward, you can now cancel notifications from any apps.

You need to register your app as NotificationListenerService, then call NotificationListenerService.cancelNotification(String pkg, String tag, int id) to cancel one notification.
