安卓 - 谷歌+集成问题"An Internal error has occurred"

Question

在我的android应用程序中，我想集成Google+服务。为此，我参考了快速入门指南链接。根据该链接，我已经完成了所有步骤，但在执行"创建OAuth 2.0客户端ID"的第三步(a、b、c点)时遇到了问题。由于谷歌开发人员已经改变了它的整个控制台设计，我不会从哪里得到OAuth clien ID？其他步骤我都做得很好。我提到了AndroidSDK提供的PlusSampleActivity，我使用的是google-play-services_lib库，但该演示无法正常运行。当我尝试登录时，它会打开对话框来选择gmailID。在选择之后，当我更进一步时，它不会登录，并显示toast消息"发生内部错误"。请帮助解决此问题。我引用了许多链接，但其中大多数可能使用旧的播放服务库，因此我对此没有太多想法。我也在stackoverflow上讨论了许多关于这个问题的问题，但它们不符合我的要求。我也试着调试我的代码，但Error log没有显示任何关于这方面的消息。如果有人知道这个问题的好的教程示例或解决方案，请帮助我解决它。非常感谢。

我解决了这个问题。由于我无法在新的googleapi控制台中创建OAuth Client ID，所以我面临着这个问题。然后我在旧的api控制台中从头开始执行所有步骤，我可以生成OAuth ClientID，现在我可以将它集成到我的应用程序中了。
