Libgdx - 非法状态未知位置的异常

我正在使用Android Studio 1.3和libgdx 1.6.2来创建游戏。我想将Google Play服务整合到我的游戏中，我已经在一个步骤中完成了所有工作，因为我之前没有遇到任何问题。但是，这次它给了我一个例外：

java.lang.IllegalStateException: A fatal developer error has occurred. Check the logs for further information.
        at com.google.android.gms.common.internal.zzi$zza.zzc(Unknown Source)
        at com.google.android.gms.common.internal.zzi$zza.zzr(Unknown Source)
        at com.google.android.gms.common.internal.zzi$zzc.zznQ(Unknown Source)
        at com.google.android.gms.common.internal.zzi$zzb.handleMessage(Unknown Source)
        at android.os.Handler.dispatchMessage(Handler.java:102)
        at android.os.Looper.loop(Looper.java:135)
        at android.app.ActivityThread.main(ActivityThread.java:5254)
        at java.lang.reflect.Method.invoke(Native Method)
        at java.lang.reflect.Method.invoke(Method.java:372)
        at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:903)
        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)

所以这是我除了添加baseGameUtils（成功添加）之外所做的更改。

这是我的机器人主要活动。

public class AndroidLauncher extends AndroidApplication  implements GameHelper.GameHelperListener{

    private GameHelper gameHelper;
    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (gameHelper == null) {
            gameHelper = new GameHelper(this, GameHelper.CLIENT_GAMES);
        }
        gameHelper.setup(this);

                return gameHelper.isSignedIn();
            }

            @Override

                            gameHelper.beginUserInitiatedSignIn();
                        }

                } catch (final Exception ex) {

                }
            }

            @Override

                Games.Leaderboards.submitScore(gameHelper.getApiClient(), "CgkI6ZHYr9IEEAIQBg", score);
            }

                    startActivityForResult(Games.Leaderboards.getLeaderboardIntent(gameHelper.getApiClient(), "CgkI6ZHYr9IEEAIQBg "), 100);
                }
                else if (!gameHelper.isConnecting()) {
                    loginGPGS();

                Games.Achievements.unlock(gameHelper.getApiClient(), achievementId);
            }

            @Override

                }
                else if (!gameHelper.isConnecting()) {
                    loginGPGS();
                }

            }


        }), config);
    }

    @Override

        super.onStart();
        gameHelper.onStart(this);

    @Override

        super.onStop();
        gameHelper.onStop();

    }

    @Override
    public void onSignInFailed() {

    }

    @Override
    public void onSignInSucceeded() {

    }
}

我不知道这里出了什么问题。提前致谢。
