Registration ID become "NotRegistered" for no reason

Question

During April, we've start receiving a lot of 'NotRegistered' errors. According to the Google docs it should happen only if app was uninstalled or updated, but in our case token can "expire" in ~40 minutes even if absolutely nothing happen with device.

And what makes things even worth is that if, let's say reg_id_1 "expired" and server returns 'NotRegistered' error - we push client to register again, but GCM provides same token which is 'NotRegistered'. App update do not help. Only reinstall or user reset(android user) helps.

So the question is - does anyone encounter the same issue and/or has some solution ?

P.S. I wonder, can it be connected to the April ClientLogin shutdown and something gone wrong on Google servers ? https://plus.google.com/+GoogleDevelopers/posts/RK1pw9Cy4Sd

Answer 1

There may be several reasons why this error would be firing on the server

• App was uninstalled
• ID expires. Prior to that you get notifed on your server that you should reintitiate the registration.
• Users's change their google account and they send the new ID
• Update to your app causes a new ID, old one expires.

It's best to remove the dead ID's from your DB and stop sending messages there.
