I got rid of it (works for Android 5 and below):
NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); Bitmap notificationLargeIconBitmap = BitmapFactory.decodeResource( context.getResources(), R.drawable.notification_icon_big); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.ic_notification_systray) //.setLargeIcon(notificationLargeIconBitmap) .setContentTitle(context.getString(R.string.app_name)) .setContentText(msg) .setColor(context.getResources().getColor(R.color.blue)) .extend(new NotificationCompat.WearableExtender().setBackground(notificationLargeIconBitmap));
