"signInSilently(): failure" when trying to sign in to GooglePlay Game Services with LibGDX

Question

I have been trying to add Google Game Services to my LibGDX project for the past 3 days now at first I tried the LibGDX tutorials but all of them seem to be outdated. Then I was advised to use the Google Game Services official code

LibGDX: How to Implement Google Play Game Services?

I imported the sample project TypeANumber and tried to add the code to my project but when I try to sign in I'm getting the "signInSilently(): failure" error and it crashes when I try to open the leaderboards and achievements on both the debug and signed APKS.

Here is my code:

AndroidLauncher:

     private void signInSilently() {
            Log.d(TAG, "signInSilently()");

            mGoogleSignInClient.silentSignIn().addOnCompleteListener(this,
                    new OnCompleteListener<GoogleSignInAccount>() {
                        @Override
                        public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
                            if (task.isSuccessful()) {
                                Log.d(TAG, "signInSilently(): success");
                                onConnected(task.getResult());
                            } else {
                                Log.d(TAG, "signInSilently(): failure", task.getException());
                                onDisconnected();
                            }
                        }
                    });
        }

    @Override
    public void showLeaderboards(){
        runOnUiThread(new Runnable() {
            public void run() {
                onShowLeaderboardsRequested();
            }
        });
    }

    @Override
    public void showAchievements(){
        runOnUiThread(new Runnable() {
            public void run() {
                onShowAchievementsRequested();
            }
        });
    }

Manifest:

In my build.gradle i added:

 compile "com.google.android.gms:play-services-games:11.8.0"
 compile "com.google.android.gms:play-services-auth:11.8.0"

Answer 1

From 1^st look of your question, It seems that you're keeping meta data outside the application tag but should be inside application tag in AndroidManifest.xml file

Like this :

  <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/GdxTheme" >

        <activity
            android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />

        <activity
            android:name="com.harrybanda.blaster.AndroidLauncher"
            android:label="@string/app_name" 
            android:screenOrientation="portrait"
            android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

      <meta-data android:name="com.google.android.gms.games.APP_ID"
                 android:value="@string/app_id" />

      <meta-data android:name="com.google.android.gms.version"
                 android:value="@integer/google_play_services_version"/>
    </application>

StatusCode 4 (SIGN_IN_REQUIRED) error means client attempted to connect to the service but the user is not signed in.

Here is my AndroidLauncher class

public class AndroidLauncher extends AndroidApplication implements MyServices {

    private GoogleSignInClient mGoogleSignInClient;

                }
            });
    }

    private void welcomeMessage(String name){

        Toast toast = Toast.makeText(this, greetingMsg + name, Toast.LENGTH_LONG);
        toast.setGravity(Gravity.TOP, 0, 0);
        View view = toast.getView();
        TextView text = (TextView) view.findViewById(android.R.id.message);
        toast.show();
        greetingDisplayed=true;

    }

    @Override

        super.onActivityResult(requestCode, resultCode, intent);

        if (requestCode == RC_SIGN_IN) {
          Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(intent);

          try {
             GoogleSignInAccount account = task.getResult(ApiException.class);
             greetingMsg="Welcome, ";
             onConnected(account);
          } catch (ApiException apiException) {
             String message = apiException.getMessage();
             if (message == null || message.isEmpty()) {
                message = getString(R.string.signin_other_error);
             }

             onDisconnected();
           }
        }
    }

    @Override
    protected void onResume() {
       super.onResume();
       signInSilently();
   }

   private void signOut() {

      if (!isSignedIn()) {
          Log.w(TAG, "signOut() called, but was not signed in!");
          return;
      }

      mGoogleSignInClient.signOut().addOnCompleteListener(this,
            new OnCompleteListener<Void>() {
                @Override

                    boolean successful = task.isSuccessful();
                    Log.d(TAG, "signOut(): " + (successful ? "success" : "failed"));

                    onDisconnected();
                }
            });
   }

    private void onDisconnected() {

       mLeaderboardsClient = null;
       mPlayersClient = null;
    }

    @Override
    public void submitScore(int score){
        if(isSignedIn())
         mLeaderboardsClient.submitScore(getString(R.string.leaderboard_id), score);
    }

    @Override
    public void showLeaderBoard() {
       if(isSignedIn())
          mLeaderboardsClient.getLeaderboardIntent(getString(R.string.leaderboard_id))
            .addOnSuccessListener(new OnSuccessListener<Intent>() {
                @Override
                public void onSuccess(Intent intent) {
                    startActivityForResult(intent, RC_LEADERBOARD_UI);

   }

   private void handleException(Exception e, String details) {
       int status = 0;

      if (e instanceof ApiException) {
          ApiException apiException = (ApiException) e;
          status = apiException.getStatusCode();
      }

      String message = getString(R.string.status_exception_error, details, status, e);

      new AlertDialog.Builder(this)
            .setMessage(message)
            .setNeutralButton(android.R.string.ok, null)
            .show();
    }   
}

And MyServices interface

interface MyServices{

    void startSignInIntent();
    boolean isSignedIn();
    void showLeaderBoard();
    void submitScore(int score);
}

First time I call startSignInIntent() of interface by myself after user install app.
