Hi,

I'm using Pushsharp to send GCM notifications and when I send to a
particular registration Id the DeviceSubscriptionExpired callback is being
fired.

This plugin doesn't seem to cater for this scenario as once there's a
Token stored it continues to use that without checking if it's still valid.

Can you advise when I should be calling the unregister method?

Hi @JohnMcAvinue ,

were you able to find a workaround?

Same issue occurs to me.

When an application is updated, it should invalidate its existing registration ID, as it is not guaranteed to work with the new version. Because there is no lifecycle method called when the application is updated, the best way to achieve this validation is by storing the current application version when a registration ID is stored.

The 'periodical' refresh never happened, and the registration refresh is not included in the new GCM library.

The only known cause for registration ID change is the old bug of apps getting unregistered automatically if they receive a message while getting upgraded. Until this bug is fixed apps still need to call register() after upgrade, and so far the registration ID may change in this case. Calling unregister() explicitly usually changes the registration ID too.

The suggestion/workaround is to generate your own random identifier, saved as a shared preference for example. On each app upgrade you can upload the identifier and the potentially new registration ID. This may also help tracking and debugging the upgrade and registration changes on server side.

Just released a new version that sends registration each time register is called. Let me know if fixes the issue, if not reopen this issue.

Thanks for doing this. I ended up hacking your code so it doesn't persist the token and registers all the time. It seems to work well. Thanks for all your hard work!
