Question

The following code does not work. Also try this instead of getapplicationcontext. I need a hint:

public class AlarmReceiver extends BroadcastReceiver {
     @Override
     public void onReceive(Context context, Intent intent) {     
         NotificationCompat.Builder nb = new NotificationCompat.Builder();
         nb.setContentTitle("title");
         nb.setContentText("message");
         nb.setSmallIcon(R.drawable.ic_launcher);
         NotificationManager nm = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
         final Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
         notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
         final PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);
         nb.setContentIntent(contentIntent);
         Notification notification = nb.getNotification();
         nm.notify(0, notification);
      }

    }

And how could I remove the Notification after onclick?

UPDATE:
I’v solved a mistake. But there is still one mistake:

Answer 1

Replace getSystemService with context.getSystemService!
