[aerogear-dev] FCM: Cordova/Android bug ?

[Matthias Wessendorf]

I looked here:
https://developers.google.com/cloud-messaging/android/android-migrate-fcm#remove_registration

It says that we no longer need, but this:
https://github.com/aerogear/aerogear-android-push/blob/3.0.1/aerogear-android-push/src/main/java/org/jboss/aerogear/android/unifiedpush/gcm/AeroGearGCMPushRegistrar.java#L144-L148

was replace with explicit FCM getToken() call:
https://github.com/aerogear/aerogear-android-push/blob/4.0.0/aerogear-android-push/src/main/java/org/jboss/aerogear/android/unifiedpush/fcm/AeroGearFCMPushRegistrar.java#L143-L147

I think I am a bit over asked here, on the Android internals...

Also, looks like we are not the only ones, seeing that problem :)
