java - GamesClient 未连接。错误 : "Call connect() and wait for onConnected() to be called."

Question

我正在尝试使用 GamesClient 来使用 Google Play 游戏服务的排行榜。现在我有了它，所以当单击 importbutton 时，GamesClient 用于提交一些分数。如下所示，我收到一条错误消息，提示 connect() 并等待 onConnectd() 被调用。

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，但没有太多答案。看起来人们仍在学习——就像我自己一样。 :)

如果您正在使用 BaseGameActivity，请不要调用 GamesClient.connect()。使用 BaseGameActivity 的优势在于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。

此外，请记住，当您的 Activity 获得 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。
