Not able to send GCM message from Device to server

[Krishna Kishore k]

Hello, 

My project ID got whitelisted recently. And I have implemented the server side code for CCS using Java and Smack library. 

I am able to send message from my server to the device by using the Registration id of a device and have also received ACK from GCM server. 

But the problem is while sending the message from Device to server. Thought the server has logged in to GCM, I don't think the message sent from device is reaching the server. I have used the same project id in both my client and server side code. 

The client side code does not throw any error or receive any ACK or NACK from GCM server. It just sends the message and thats it, it is never reaching my CCS server code. 

My client side code using  gcm.send(GCM_SENDER_ID + "@gcm.googleapis.com", id, GCM_TIME_TO_LIVE, data); to send message to the server.

Did anyone face similar issue? Please provide your suggestions on resolving the issue. 

Thanks,

Kishore

hello,

I am also working on a CCS implementation on GCM server. I am not able to receive anything after deploying on google app engine. Are you receiving ACK after deploying on google app engine when you mentioned it in this:

"I am able to send message from my server to the device by using the Registration id of a device and have also received ACK from GCM server. "

I am looking for any and every help / hint I can find. I would like o know how you are receiving ACK after deploying on google app engine.

Any help will be appreciated.

Thanks!

Hi,

I am using the server side implementation code given in the below site.

http://www.grokkingandroid.com/xmpp-server-google-cloud-messaging/

Also I am using by own Tomcat server to deploy the application. Use the debug mode enabled option  to see if it is connecting properly or not. 

You can even debug from your localhost in eclipse and even localhost can receive ack and nack messages. So test it out on localhost first and then move it to App engine. 

Thanks,
Kris
