Notification shows after android app is force closed

Question

I have googled this non stop today and could not find anything. My scenario is the following:

I have an Android app that auto replies to incoming messages. I have

Answer 1

The method that I used to kill the processes when I swipe apps from the recents is: in the first activity of the app, in the method OnDestroy I write that "the process have to kill". In this way I call the OnDestroy method of the process and so the process really kills himself and the notification is removed. Specifically, in the first Activity:

    @Override
public void onDestroy() {
  super.onDestroy();

  Intent intent = new Intent();
  intent.setAction(Service.MY_ACTION_FROMACTIVITY);
  intent.putExtra(Service.CMD, Service.CMD_STOP);
  sendBroadcast(intent);

}

So the following operations are:

@Override
public void onDestroy() {
    // TODO Auto-generated method stub
    barNotification.cancel(NOTIFICATION);

    sensorManager.unregisterListener(this);

    this.unregisterReceiver(myServiceReceiver);
    super.onDestroy();
}

I hope that I can help you.
