I'm trying to develop a game where the user after sign in in Play Games is forwarded to another Activity. But on this second Activity I don't know how to get his username. Do I have to Sign in again (this time on the second Activity) to obtain it?
I tried with
GoogleSignIn.getClient(this, GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN).toString();
but it returns something like com.google.candroid.gms.auth.api.signin@ and I what I want is his username in Play games, not this.
I was reading this solution but here I've got to create a new GoogleApiClient again to get the it.
