问题
I was trying to set this example: https://code.google.com/p/gcm/source/browse/#git%2Fgcm-client up and running.
The GoogleAPI project has been successfully created, according to the guide: http://developer.android.com/google/gcm/gs.html
However, I have the following problem: on some devices I get SERVICE_NOT_AVAILABLE no matter what.
W/System.err: java.io.IOException: SERVICE_NOT_AVAILABLE W/System.err: at com.google.android.gms.gcm.GoogleCloudMessaging.register(Unknown Source)
Some statistics:
- Nexus 7, android 4.2.2: GCM example works perfectly
- Nexus 4, android 4.2: GCM example works perfectly
- Nexus S, android 4.2.2: GCM example works perfectly
- Samsung Galaxy 3: SERVICE_NOT_AVAILABLE in 100% cases
- Samsung Galaxy, android 2.3.6: SERVICE_NOT_AVAILABLE in 100% cases
- Motorola Xoom, android 4.1.2: SERVICE_NOT_AVAILABLE in 100% cases
- HTC Desire HD, android 2.3: SERVICE_NOT_AVAILABLE in 100% cases
It's the same code, the same apk file, various google accounts. I tried to switch back to GCMRegistrar methods and they actually work. So the question is: are new GCM methods in sort of beta? How to make them work on other devices, not just 'pure' Google Android devices?
Update: In fact, I found the solution here
回答1:
Sometimes it happened due to time syn with GCM. Please have a look at the time, if it is correct. If possible then reset.
Two more thing to check, if you are using a emulator then please make sure that you have the google api running on the emulator. and second gcm.jar is included on your project.

Check your phone has an active network connection. I had this issue and then i realized that my test device disconnected from the wifi :)

this is super stupid, but I have same error because I had "restrict app background data" option enabled for google services on my xperia)
