设备未收到来自GCM的消息

Question

I'm trying to use GCM to send notification from server to our device.

Everything follow this guide: http://hmkcode.com/android-google-cloud-messaging-tutorial/

After create an application, a server key, and my app receive a token from GCM, i send message to GCM using those key, token.

Here is what GCM reply to my request:

{"multicast_id":8176461798984692114,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1420006852349947%174fccaaf9fd7ecd"}]}

This Json indicate that message already sent successful. But our device didn't receive anything.

We did this for few time, even changing server key to browser key, change project, or use example from google site instead of above guide example, but nothing work. So i want to know what the possible problem for device not receiving message.

Thank you in advance!

As you mentioned in your question that your notification has been sent, so then the issue is on android code, you have to cross check your android code. Look at this tutorial...

And cross check your android code with this one, and then debug your android code.
