问题
I made an app using GCM for notifications. I used this tutorial and my code is pretty much identical
http://developer.android.com/google/gcm/client.html
I'm testing on physical devices and on some of the devices I am getting a SERVICE_NOT_AVAILABLE error when I try to register the device with GCM.
I have an exponential backoff setup so it does retry over time.
It works on about half of my test devices the others get a SERVICE_NOT_AVAILABLE error. Looked all over and haven't found a solution yet.
Any help would be greatly appreciated. Thank You!

SERVICE_NOT_AVAILABLE might mean that your device can't read the response or there was a 500/503 from the server. You already have a exponential back-off so server side shouldn't be a problem I suppose. See if you have "com.google.android.c2dm.intent.REGISTRATION" to the GCMBroadcastReceiver in your manifest and you are handling that. Check out : GCM SERVICE_NOT_AVAILABLE on Android 2.2 for detailed solution, if you haven't already. Comment if that works.

You will also get this error if you simply do not have network connection.
