All you need to do, is to add a style to your content like below:

      Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_dialog_alert);

      NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

              .setStyle(new NotificationCompat.BigTextStyle().bigText(message));

      Notification notification =;
      NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
