GCM gives same registration_id multiple times

Today I tried to get a registration_id from gcm services. It worked fine. But every time when I uninstall my app (that includes deleting all shared preferences for that app) and reinstalled the app to get a new registration_id, I got the exact same registration_id. That happened now 5 times so I guess there is something wrong. Or is that normal?

That's normal. GCM usually doesn't generate a new Registration ID for the same application and the same device.

The only way I managed to get a new Registration ID for the same app and the same device was to uninstall the app, send several messages to the old Registration ID until I got a NotRegistered error, and only then install the app again.
