libGDX Google Play-Spieldienste - Android

Question

Ich versuche, Google Play Game Services in libGDX-Projekt zu implementieren. In meinem Android-Projekt sieht die MainActivity wie folgt aus:

public class MainActivity extends AndroidApplication implements 
    GameHelper.GameHelperListener, ActionResolver { 

GameHelper gameHelper; 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    gameHelper = new GameHelper(this, GameHelper.CLIENT_ALL); 
    gameHelper.enableDebugLog(true); 

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE); 

    AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration(); 
    cfg.useGL20 = false; 

    initialize(new CJSGame(this), cfg); 
    gameHelper.setup(this); 

} 

@Override 
public void onStart() { 
    super.onStart(); 
    gameHelper.onStart(this); 
} 

@Override 
public void onStop() { 
    super.onStop(); 
    gameHelper.onStop(); 
} 

    @Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // TODO Auto-generated method stub 
    super.onActivityResult(requestCode, resultCode, data); 
    gameHelper.onActivityResult(requestCode, resultCode, data); 
} 

@Override 
public boolean getSignedInGPGS() { 
    // TODO Auto-generated method stub 
    return gameHelper.isSignedIn(); 
} 

@Override 
public void loginGPGS() { 
    // TODO Auto-generated method stub 
    try { 
     runOnUiThread(new Runnable() { 
      public void run() { 
       gameHelper.beginUserInitiatedSignIn(); 
      } 
     }); 
    } catch (final Exception ex) { 
    } 
} 

@Override 
public void submitScoreGPGS(int score) { 
    // TODO Auto-generated method stub 
    Games.Leaderboards.submitScore(gameHelper.getApiClient(), 
      getString(R.string.leaderboard1_id), score); 
} 

@Override 
public void unlockAchievementGPGS(String achievementId) { 
    // TODO Auto-generated method stub 
    Games.Achievements.unlock(gameHelper.getApiClient(), achievementId); 
} 

@Override 
public void getLeaderboardGPGS() { 
    // TODO Auto-generated method stub 
    startActivityForResult(
      Games.Leaderboards.getLeaderboardIntent(
        gameHelper.getApiClient(), 
        getString(R.string.leaderboard1_id)), 100); 
} 

@Override 
public void getAchievementsGPGS() { 
    // TODO Auto-generated method stub 
    startActivityForResult(
      Games.Achievements.getAchievementsIntent(gameHelper 
        .getApiClient()), 101); 
} 

@Override 
public void onSignInFailed() { 
    // TODO Auto-generated method stub 
    System.out.println("Sign in failed"); 
} 

@Override 
public void onSignInSucceeded() { 
    // TODO Auto-generated method stub 
    System.out.println("Sign in succeeded"); 
} 
} 

Wenn ich versuche, die Anwendung auf Android-Gerät laufen zu lassen, habe ich am Ende in der logcat mit Illegal Fehlern auf:

03-13 10:23:40.766: E/AndroidRuntime(31339): FATAL EXCEPTION: main

Jede Hilfe bitte ??

Edit: Ich habe bereits den Metadaten-Tag in der Manifest-Datei

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

Answer 1

gelöst, aktivierte ich adb logcat und fand, dass es eine anderer Metadaten-Tag ist in der Manifest-Datei fehlt:

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

Nur dieses Tag hinzugefügt und es funktioniert ordnungsgemäß.
