Hi Sir,
I am a java developer currently working on a android notification project. I am having a problem with what to keep as a unique key for my (3rd party) database after registering to GCM.
The registeration Id which GCM provides on registering the android device, often changes when we re-install the app. In order to avoid duplicacy in 3rd party database, what should we use as unique key in the database, so that using this field I can update the old registration Id with new registration Id whenever app is reinstalled.
