我很想知道如何让默认的“appengine connected Android project”工作。 我正在使用eclipse Luna（4.4.2）和谷歌插件（使用谷歌应用引擎SDK 1.9.18）。 我通过输入相关范围（项目名称，包名称，API密钥和项目编号）创建了默认项目。 然后我通过运行xxxxx-AppEngine作为Web应用程序启动了本地Web服务器。 然后，当我尝试访问：http://localhost:8888/时，我在控制台中收到以下错误：

此外，当我运行Android客户端并按“REGISTER”时，我得到相同的500错误。

我该如何解决这个问题？

1 个答案:

答案 0 :(得分：1)

当我更新到GAE的SDK版本1.9.18时，我遇到了同样的问题。最后我想出了解决方案：更新java。在我这样做之后，一切都顺利进行了！

我猜测端点现在需要Java版本1.7.0_51-b13或更高版本，在Guava类的源代码中由this comment判断给我们带来了麻烦。

作为参考，今天可用的Java 7版本是1.7.0_76。
