Spurious NotRegistered Error responses from GCM servers

[GoogleCodeExporter]

Steps-
1. Install a GCM client app on android device.
2. App should register device with GCM and send registration ID to your server.
3. Server sends push via GCM server, it works for few days/months.
4. After some days, GCM server started returning "NotRegistered".
5. Though app is still installed on that device. 

Please confirm if app should re-register a device if the version of Android OS 
it’s running has been updated.

Please also correct the documentation at below link, if required-

This still happens even if you re-register after the Android OS is upgraded, so 
its not just that. Also, I'm not certain its a deterministic thing, that this 
will happen every time, but it will happen reliably to many of users of an app.
