【问题描述】：

我正在尝试将 Google play 游戏服务实施到 libGDX 项目中。 在我的 android 项目中，MainActivity 如下所示：

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");

当我尝试在 android 设备上运行应用程序时，我最终在 logcat 中出现 IllegalStateException 错误：

有什么帮助吗？？

编辑：我已经在清单文件中有元数据标签

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

【参考方案1】：

已解决，我启用了adb logcat，发现manifest文件中又少了一个元数据标签：

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

刚刚添加了这个标签，它工作正常。
