我一直试图在我的示例Android应用上实现G +登录，但仍然遇到同样的问题。
我已经完成了这个： https://developers.google.com/+/mobile/android/getting-started
并且： https://developers.google.com/+/mobile/android/sign-in
当我运行它时，我点击＆＃34; G +登录＆＃34;按钮。然后我选择一个帐户，然后单击“确定”。然后我看到一个Toast说＆＃34;发生内部错误＆＃34;
该帐号选择器和随后的Toast发生在此行：
startIntentSenderForResult(mConnectionResult.getResolution().getIntentSender(),
RC_SIGN_IN, null, 0, 0, 0);
我使用的是Android Studio 0.8.2。项目没问题，并且使用正确的调试证书（我使用相同的包名称使Maps v2工作）。
这主要是从上面两个网址中复制/粘贴，因此没有拼写错误。
有什么建议吗？非常感谢，我很困惑。

答案 0 :(得分：1)
解决方案非常简单......我需要在Google Developers Console中填写项目同意屏幕中的必填字段。特别是电子邮件地址和产品名称。在我填写完毕后，应用程序运行没有任何问题。
地图v2在没有填写同意屏幕的情况下运行，因此我认为同样适用于G +登录。但这种假设并不适用。
所以，如果你得到＆＃34;发生内部错误＆＃34;你发誓你做了指南的所有步骤，先去检查你的同意屏幕。该指南没有明确谈论同意屏幕。
