我是 Android 编程的新手，我正在尝试执行一个将图像发送到服务器并返回结果的应用程序。出于这个原因，我正在关注 App Engine Connected Android 上的谷歌教程 2。 问题出现在运行应用程序的电话端时，因为模拟器没有启动，如果我用真实设备尝试它，它会说“端点注册失败”，结果的屏幕截图图像在链接 1 中.
我已将 LOCAL_ANDROID_RUN 设置为 true，并且还插入了相应的项目编号和 api_keys。 不知道哪里出了问题，控制台和logcat输出如下:

非常感谢。
最佳答案
- 确保 CloudEndPointUtils 类中的常量 LOCAL_ANDROID_RUN 设置为 false，这意味着我们的服务器未在本地设置。
- 通过右键单击项目->google->部署到应用引擎，将您的 -AppEngine 项目部署到 google appEngine。
- 将部署到 CloudEndPints.java 后显示的 url 添加到变量 LOCAL_APP_ENGINE_SERVER_URL
