GamesClient 未连接。错误：“调用 connect() 并等待调用 onConnected()。”

Question

我正在尝试使用 GamesClient 来使用 Google Play 游戏服务的排行榜。现在我有它，所以当点击importbutton 时，GamesClient 用于提交一些分数。如下所示，我收到一条错误消息connect() and wait for onConnectd() to be called.

我做错了什么？我在一些教程中看到了一个叫做PlusClient 的东西。我需要以某种方式吗？如果需要，我可以提供更多代码。

StackOverflow 上似乎有很多关于这个新的 Google Play 游戏服务的问题，但没有很多答案。看起来人们还在学习——比如我自己。 :)

Answer 1

如果您使用的是BaseGameActivity，请不要拨打GamesClient.connect()。使用BaseGameActivity 的优点是它可以为您处理所有连接样板。您所要做的就是覆盖 onSignInSucceeded 并从那里进行 API 调用。在获得onSignInSucceeded 之前不要进行任何游戏 API 调用。

另外，请记住，当您的活动收到 onStop 时，游戏 API 将断开连接。之后，当它随后获得onStart 时，您将再次等待onSignInSucceeded，然后再进行任何 API 调用。

Answer 2

您正在尝试在建立连接之前提交分数。

就像错误所说的那样，您应该等待 onConnected() ，然后才允许提交分数。示例：您应该只在连接后显示按钮

如果你正在扩展 BaseGameActivity，你应该这样做：

int isGooglePlayServiceAvilable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if (isGooglePlayServiceAvilable == ConnectionResult.SUCCESS) {
    beginUserInitiatedSignIn();
} else {
    GooglePlayServicesUtil.getErrorDialog(isGooglePlayServiceAvilable, MainMenu.this, REQUEST_DIALOG).show();
}

然后，你应该重写这些方法：

@Override
public void onSignInSucceeded() {
   super.onSignInSucceeded();
   // allow to submit scores
}

@Override
public void onSignInFailed() {
    super.onSignInFailed();
    // do not allow to submit scores
}
