我正在使用Facebook和Google+ API为我的第一次（登录）活动创建登录按钮。我只是关注开发者页面中的教程，并将它们一起实现。 Facebook按钮工作正常，但当我点击谷歌+按钮时没有任何反应。我做错了什么？
代码：
登录活动：

如果mConnectionResult中的hasResolution（）方法失败，我建议您显示错误消息，这导致我解决了问题，在我的情况下，这是由于Google Play服务版本之间的兼容性问题。因此，您可以通过更改以下内容的resolveSignInErrors来更详细地了解可能出现的问题：
private void resolveSigInErrors() {
if(mConnectionResult.hasResolution()){
try {
startIntentSenderForResult(mConnectionResult.getResolution().getIntentSender(),RC_SIGN_IN,null,0,0,0);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
mGoogleApliClient.connect();
}
}
else {
// Show dialog using GooglePlayServicesUtil.getErrorDialog()
GooglePlayServicesUtil.showErrorDialogFragment(mConnectionResult.getErrorCode(),this,RC_SIGN_IN);
}
}
这将打印Google Play服务提供的特殊视图中出现的问题，它甚至可以帮助您解决错误。
