I am doing Push Notification for this, and I follow the link http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/
All things working well but when I want to send the message from PHP page to registered device after click send message gets blank but not received on either real device or Emulator.
I also had the same issue it get resolved just check my post If still you are having then please provide the code for the same.
here is my android and php code Register.java
