Is there an easy way to get an authentication token (like OAuth2) from Google Play that can be passed to a server to validate the user’s identity? I’ve looked at Unity’s builtin Android classes, and the Social API, and Google Play plugin here: GitHub - playgameservices/play-games-plugin-for-unity: Google Play Games plugin for Unity and a few other places, but haven’t found an answer anywhere yet. Surely someone has managed to get this to work, right?
Bump. Anyone? Someone out there must have made an Android game that talks to a server?
