Device Token problem
3 CommentsSorted by Newest First
Hey.
Just to confirm-- the device token is unique per (physical device AND package name). If you have changed the package name and changed the devices, that would explain why there are multiple tokens.
As a workaround, you can either delete the users and re-create them with empty push fields, and re-register them or you can use business logic to modify the user collection and remove values in the user's `_push` field. This guide here will point you in the right direction for using the `CollectionAccess` module of BL: http://devcenter.kinvey.com/rest/guides/business-logic#Mergingdataintwocollections
Yeah, so the problem is that unregistering for GCM requires the Application context, which would require you to build the app with the invalid package names on the same devices.

>are you using the same user (username/password) on different devices and registering on each of them?
Yes
>Or have there been changes to the package name of your application?
Yes
Also I have un-installed and reinstalled the app. I believe each un-install/re-install cycle gets a new token.
>Note the above behavior is what's expected if the same user has registered on multiple devices, but as you are only using two there should only be two in that array.
Yes, I agree, there should only be two tokens.

Hey,
are you using the same user (username/password) on different devices and registering on each of them? Or have there been changes to the package name of your application?
Note the above behavior is what's expected if the same user has registered on multiple devices, but as you are only using two there should only be two in that array.
According to this: http://developer.android.com/google/gcm/gcm.html the registration id should be unique per app and device-- so even repeated calls to register on the same device with the same package name should have the same push registration id.

I only have two Android devices, but I see this in the Push field of my user record. Why so many GCM tokens?

PS, I'm getting multiple notifications for each push.
