Google登录无法与Play Games Services启用功能一起使用，但不能与

Question

First of all let's have a look at the code that works perfectly fine. This is how we setup our Google Api Client:

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestEmail() 
                .requestIdToken(AppActivity.this.getResources().getString(R.string.server_client_id))
                .build();

GoogleSignIn.googleApiClient = new GoogleApiClient.Builder(this)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

Then this for connecting:

// GPGS needs optional apparently, at least it crashes without. 
// Normal (non GPGS) SignIn works either way
googleApiClient.connect(SIGN_IN_MODE_OPTIONAL); 

Then we call login. The overlay appears, I select my email, login runs through and all is fine:

public static void loginGoogleSDK()
{
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(googleApiClient);
    GameApplication.getActivity().startActivityForResult(signInIntent, RC_SIGN_IN);
}

---

Now there's the Google Play Games Services login which is quite similar, but does always return a User Cancelled error. The GPGS overlay appears, one can select an email, then it disappears and the error is given back:

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
            .requestEmail()
            .requestIdToken(AppActivity.this.getResources().getString(R.string.server_client_id))
            .build();

GoogleSignIn.googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Games.API)
            .addScope(Games.SCOPE_GAMES)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();

Connect and login are completely equal.

The User Cancelled result code, comes back here:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // cancelled = true when using GPGS 
    GameLog.i("On Activity Result called, cancelled? " + (resultCode == RESULT_CANCELED) );


    // [Other code for handling login....]


}

Does anybody know what's causing this and how we can get login with Google Player Games Services working?

Answer 1

My code was 100% correct.

I had to add my email under "Testers" in the Google Play Developer Console under my Game.

This is not necessary for Google+ SignIn, but it is for games.

Answer 2

我有类似的问题，但是从我的阅读中可以看出，您不能将Auth.GOOGLE_SIGN_IN_API与Games.API一起使用。
