关于 Android Studio 上的 Google Play 游戏服务

Question

我正在尝试在我的项目中添加排行榜和成就系统大约 3 天...

我可以登录我的应用，但是当我尝试打开排行榜时，它会说：

我该如何解决这个问题？

我写了这段代码：

            case R.id.Enbasarili:
            startActivityForResult(Games.Leaderboards.getLeaderboardIntent(mGoogleApiClient,
                    getResources().getString(R.string.leaderboard_en_cok_70_ve_ustu_basari_gosterenler)), RC_UNUSED);
            break;

感谢您的帮助...

尝试检查这些文档 - Accessing the Play Games Services APIs in Your Android Game 和 Get Started with Play Games Services for Android

获取 Google Api 客户端并连接

您的游戏必须引用 GoogleApiClient 对象才能对 Google Play 游戏服务进行任何 API 调用。使用 GoogleApiClient.Builder 类在 onCreate() 中创建 GoogleApiClient 对象。例如：

private GoogleApiClient mGoogleApiClient;

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

    // Create the Google Api Client with access to the Play Games services
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Games.API).addScope(Games.SCOPE_GAMES)
            // add other APIs and scopes here as needed
            .build();

    // ...
}

为了让您的游戏与 Google Play 游戏服务进行通信，您的客户端必须首先建立连接。一旦您的游戏不再需要访问这些服务，您可以断开客户端连接。

编辑：

Implementing Sign-in in Your Android Game

为了使用 Google Play 游戏服务，您的游戏需要实现用户登录，以通过 Google Play 游戏服务验证您的玩家身份。如果用户未通过身份验证，您的游戏在调用 Google Play 游戏服务 API 时会遇到错误。

private static int RC_SIGN_IN = 9001;

private boolean mResolvingConnectionFailure = false;
private boolean mAutoStartSignInflow = true;
private boolean mSignInClicked = false;

// ...

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    if (mResolvingConnectionFailure) {
        // Already resolving
        return;
    }

    // If the sign in button was clicked or if auto sign-in is enabled,
    // launch the sign-in flow
    if (mSignInClicked || mAutoStartSignInFlow) {
        mAutoStartSignInFlow = false;
        mSignInClicked = false;
        mResolvingConnectionFailure = true;

        // Attempt to resolve the connection failure using BaseGameUtils.
        // The R.string.signin_other_error value should reference a generic
        // error string in your strings.xml file, such as "There was
        // an issue with sign in, please try again later."
        if (!BaseGameUtils.resolveConnectionFailure(this,
                mGoogleApiClient, connectionResult,
                RC_SIGN_IN, getString(R.string.signin_other_error))) {
            mResolvingConnectionFailure = false;
        }
    }

    // Put code here to display the sign-in button
}

请参阅sample 以更好地了解 Google Play 游戏的代码实现。

希望这会有所帮助。
