我的项目存在问题，我希望将Google Cloud Endpoints与Android连接。我仍然得到同样的错误：

我读到有些人有这个问题，但没有写出如何解决它。我创建了新的debug.key并获得了新的sha1但不起作用。还试图用新包创建新的Android项目 - 没有用。

你在Windows上使用ADT吗？如果是，则可以在Windows-＆gt; Preferences-＆gt; Android-＆gt; Build中获取调试密钥库的sha1指纹用于调试模式。

我在Tic Tac Toe示例中遇到了同样的错误。
对我来说，事实证明我错误地阅读了这些说明。
在Android代码中，尝试更换Android客户端密钥：
"660102392535.apps.googleusercontent.com"
使用您的Web客户端密钥：
"660102392535-dobseln3gde8e6lqnd2v80l3oh6mm1nh.apps.googleusercontent.com"。
我知道这没有意义，但它对我有用。

在“AppConstants.java”（来自教程的名称）中，我将WEB_CLIENT_ID更改为与GAE凭证屏幕中相同的Web客户端ID。根据教程，这应该是Android客户端ID，因此存在问题。

我的问题是我使用发布密钥库中的SHA1创建了凭据。我想您已经意识到必须使用调试密钥库，但也许您可以尝试使用发布版本，导出已签名的apk，将其复制到您的手机并从那里安装。在我的案例中工作。
