       protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.ana_sayfa);


        apiClient = new GoogleApiClient.Builder(this)
                .addApi(Games.API)
                .addScope(Games.SCOPE_GAMES)
                .enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
                    @Override
                    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
                        Log.e("HATA", "Google Play Oyun servisine bağlanamadı.Lütfen bağlantınızı kontrol ediniz.");
                        finish();
                    }
                }).build();
}

我希望用户在打开应用程序时登录到 google play 服务。我收到以下错误。

java.lang.IllegalStateException: A fatal developer error has occurred. Class name: zzf. Start service action: com.google.android.gms.games.service.START.

我解决了这个问题。我没有在清单文件中添加以下代码

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