How to properly clear all notification once clicked?

Question

I send a few notification on the notification bar, i wanted to clear all of it when one of the notification is clicked. For now I clear one by one by using Flag. I know notificationManager.cancelAll() could clear all the notification but where should i put so that i can trigger once one of the notification is clicked.

 private static void generateNotification(Context context, String message) {     int icon = R.drawable.ic_launcher;     long when = System.currentTimeMillis();     NotificationManager notificationManager = (NotificationManager)             context.getSystemService(Context.NOTIFICATION_SERVICE);     Notification notification = new Notification(icon, message, when);     String title = context.getString(R.string.app_name);      Intent notificationIntent = new Intent(context, MainActivity.class);      // set intent so it does not start a new activity     notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |             Intent.FLAG_ACTIVITY_SINGLE_TOP);     PendingIntent intent =             PendingIntent.getActivity(context, 0, notificationIntent, 0);     notification.setLatestEventInfo(context, title, message, intent);     notification.flags |= Notification.FLAG_AUTO_CANCEL;      notificationManager.notify(msgid, notification);       //notificationManager.cancelAll(); //i wan to clear all when the notification is clicked, where should i put this line? }

My solution is to call it at onResume().

@Override protected void onResume() { super.onResume();  // Clear all notification NotificationManager nMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); nMgr.cancelAll(); }
