Hi,
Couldn’t find answers for this - On android, is it possible to login with google play, and receive an access token to send to the server to securely log the user in?
Hmm, almost. It’s possible to open a Google signin window in a webview, but since there is now address bar or anything I don’t think a user would trust it to be a legit signin page. Once we have the extension system in place it will be possible though.
Shame 
This is a dealbreaker for us
And you need the Google Play Services login now or would it be enough to get it perhaps by the end of the year?
General native SDK support would probably need to be in ~Jan-Feb for it to be relevant for us. Various mobile attribution (Tune / Appsflyer), login systems (GPlay access tokens etc) and general mobile goodness to have a modern game for a modern ecosystem…
