updating device gcm registration id on OS update

Question

I'm trying to implement update device GCM registration id on android OS update for my app to receive push notification even after OS update. I read somewhere I need to update gcm reg id for app version update and OS update. For OS version update I'm trying to use Build.VERSION.RELEASE or Build.VERSION.SDK_INT to identify OS is updated with shared preference. Which one of the above should be used to achieve this ?

Thanks for the help.

Answer 1

Build.VERSION.SDK_INT will achieve this.
