我正在尝试使用GamesClient来使用Google Play游戏服务的排行榜。现在我已经拥有它，所以当点击importbutton时，GamesClient用于提交一些分数。如下所示，我收到错误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名为PlusClient的东西。我是否需要某种方式？如果需要，我可以提供更多代码。
看来StackOverflow上有很多关于这个新的Google Play游戏服务的问题，但那里没有很多答案。看起来人们还在学习 - 就像我一样。 ：）

答案 0 :(得分：4)
如果您使用BaseGameActivity，请不要致电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，请不要进行任何游戏API调用。
此外，请记住，当您的活动获得onStop时，游戏API将会断开连接。之后，当它随后获得onStart时，您会在进行任何API调用之前再次等待onSignInSucceeded。
答案 1 :(得分：3)
您正在尝试在建立连接之前提交分数。
如错误所示，您应该等待onConnected（），然后才应该允许提交分数。示例：您应该只在连接后显示按钮
如果要扩展BaseGameActivity，则应该执行以下操作：
int isGooglePlayServiceAvilable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if (isGooglePlayServiceAvilable == ConnectionResult.SUCCESS) {
beginUserInitiatedSignIn();
} else {
GooglePlayServicesUtil.getErrorDialog(isGooglePlayServiceAvilable, MainMenu.this, REQUEST_DIALOG).show();
}
然后，你应该覆盖这些方法：
@Override
public void onSignInSucceeded() {
super.onSignInSucceeded();
// allow to submit scores
}
@Override
public void onSignInFailed() {
super.onSignInFailed();
// do not allow to submit scores
}
