Answer 1

I found out my mistake what I'm doing in my code is in GcmIntentService i comment out .setSmallIcon(R.drawable.ic_stat_gcm) so that's the reason even after receiving message i was not able to see the notification.

NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
        //.setSmallIcon(R.drawable.ic_stat_gcm)
