Not able to receive GCM message in my device, even though the server got success message

Question

I got success message as response to web server (localhost) from gcm. But the message is not received by the devices. Please help. Below is the code which I used.

Answer 1

I had same problem of receiving push messages, even though GCM server replies "Success", because of wifi privacy. When I used my company wifi, I coudn't receive message in mobile, since they were blocked GCM server port . So, even your wifi also could be a one of the reason. check it once { this answer is for others , who may face this}
