java - 尝试使用 LibGDX 登录 GooglePlay 游戏服务时出现 "signInSilently(): failure"

Question

在过去 3 天里，我一直在尝试将 Google Game Services 添加到我的 LibGDX 项目中，起初我尝试了 LibGDX 教程，但它们似乎都已过时。然后我被建议使用谷歌游戏服务官方代码

LibGDX: How to Implement Google Play Game Services?

我导入了示例项目 TypeANumber并尝试将代码添加到我的项目中，但是当我尝试登录时，我收到了 "signInSilently(): failure"错误，当我尝试打开排行榜和成就时它崩溃了调试和签名的 APKS。

这是我的代码:

安卓启动器:

     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();
            }
        });
    }

从第 1^st 看你的问题，你似乎将元数据保存在应用程序标签之外，但应该在 AndroidManifest.xml 文件

像这样:

  <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.

这是我的 AndroidLauncher 类

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

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

和MyServices接口(interface)

interface MyServices{

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

用户安装app后第一次自己调用接口(interface)的startSignInIntent()
