Question

I’ve set a notification this way:

public void onReceive(Context context, Intent intent) {
    nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    Bundle bundle = intent.getExtras();

    CharSequence from = bundle.getString("alarm_title");
    CharSequence message = bundle.getString("alarm_text");
    int notify_id = bundle.getInt("notify_id");

    Intent notifyIntent = new Intent(context, AppActivity.class);
    notifyIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notifyIntent, 0);

    Notification notif = new Notification(R.drawable.ic_menu_glases, "App Information", System.currentTimeMillis());
    notif.contentIntent = contentIntent;
    notif.setLatestEventInfo(context, from, message, contentIntent);
    notif.flags = Notification.FLAG_AUTO_CANCEL;

    nm.notify(notify_id, notif);  

}

Everything works fine and I’m happy with it. Now I’d like to cancel the notification by ID.

My 1st try failed (alarm still coming up):

AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplication(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplication(), notifyID, intent, PendingIntent.FLAG_ONE_SHOT);
if(pendingIntent != null) {
    am.cancel(pendingIntent);
    pendingIntent.cancel();  
}

And 2nd try failed too:

NotificationManager nm = (NotificationManager) getApplication().getSystemService(Context.NOTIFICATION_SERVICE);
nm.cancel(notify_id);

Anybody got an idea of how to stop the notification once set? Thank you!

Answer 1

Use this code

String ns = Context.NOTIFICATION_SERVICE;
NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
nMgr.cancel(notify_id);

In your code i changed notifyID to notify_id. The notification id should be the same as one used while creating the notification. Just check that and it should work fine as mentioned in the api.
