I am using playgameservices unity plugin to implement realtime multiplayer gaming. I successfully set up APNs to receive multiplayer invitations on iOS devices. But when I switch to Android, I did not see any notification both when running or not running the application.
I think I am missing something very basic, but, from scratch, what should I do to enable notifications for this purpose on Android side? i.e. in manifest file, on developer console etc?
Just realized that the synchronization on my Android device is disabled. So, just enabling "sync" did the trick. See https://github.com/playgameservices/play-games-plugin-for-unity/issues/525 for more details.
