安装应用程序时无法登录谷歌播放游戏服务

Question

I made google-api-client with this code

GoogleSignInOptions options = new GoogleSignInOptions
            .Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
            .requestServerAuthCode(SERVER_CLIENT_ID)
            .build();

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)                    
                .addApi(Auth.GOOGLE_SIGN_IN_API, options)
                .addApi(Games.API)                  
                .build();

and connect to service with this code

mGoogleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);

connection is successful but I can't get serverauthcode because mGoogleApiClient.hasConnectedApi(Games.API) returns false without any warning or error

@Override
public void onConnected(Bundle bundle) {

     if (mGoogleApiClient.hasConnectedApi(Games.API)) {
        Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient).setResultCallback(
               new ResultCallback<GoogleSignInResult>() {
                   @Override
                   public void onResult(GoogleSignInResult googleSignInResult) {

                       // In this case, we are sure the result is a success.
                       GoogleSignInAccount signInAccount = googleSignInResult.getSignInAccount();                          
                       mAccountAuthCode = signInAccount.getServerAuthCode();    

                       Player player = Games.Players.getCurrentPlayer(mGoogleApiClient);
                       mAccountId = player.getPlayerId();
                       Log.i(MYTAG, "login success");           


                   }
               }
        );
    } 
    else
    {           
        Log.i(MYTAG, "connected but no Games.API Why!");            
    }

Strangely if I just disconnect and reconnect , mGoogleApiClient.hasConnectedApi(Games.API) return true and all things are fine.

Also if I just relaunch app mGoogleApiClient.hasConnectedApi(Games.API) return true and all things are fine.

I wonder why I cannot connect google-play-games-service api with first try.

I'm using latest google play service sdk(10.2.4)

any advice would be appreciated

Answer 1

You may refer with this thread . Try restarting your device. If that doesn't help, then clear the cache. If issues persist, you can also try uninstalling and reinstalling Play Store app updates.

For mGoogleApiClient.hasConnectedApi(Games.API) returns false , you may check this link: GoogleApiClient.isConnected() return always false

You need to add a couple callback listeners to the Builder (or GoogleApiClient). What's most likely happening is that the login is failing because you don't have permissions yet. You need to handle that failure so that the user can authorize your app.
