App Engine连接Android项目：端点服务器失败

时间：2013-02-27 11:18:21

标签： java android google-app-engine

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的应用程序，该服务器会返回结果。出于这个原因，我正在关注App Engine Connected Android上的Google教程2。 运行应用程序的手机端时会出现问题，因为模拟器无法启动，如果我尝试使用真实设备，则会显示“使用端点注册失败”，结果的屏幕截图显示在链接中{ {3}}

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。 我不知道出了什么问题，控制台和logcat输出如下：

  1. 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。
  2. 通过右键单击项目＆gt; google-＆gt;部署到应用引擎，将-AppEngine项目部署到google appEngine。
  3. 将部署到CloudEndPints.java后显示的URL添加到变量LOCAL_APP_ENGINE_SERVER_URL

您的错误java.net.BindException: Address already in use表示本地AppEngine实例未正常启动。通常我在尝试启动本地GAE实例时看到此错误，而另一个GAE实例已将自己绑定到端口（即，我启动它两次），但在这种情况下，您的Android应用程序应该与第一个实例进行通信仍然功能。

您的问题不同 - 由于某种原因，您的初始 GAE实例无法将自身绑定到端口（我们知道这是因为Android应用无法找到任何本地GAE实例）。我会按顺序尝试以下操作，直到它起作用：

  1. 确保您的GAE运行配置设置为绑定到端口8888（如果端口设置为1024或更低，操作系统可能会拒绝绑定尝试。）
  2. 假设您使用Eclipse，请将您的GAE运行配置更改为“自动选择未使用的端口”并查看它是否正常运行。如果是，请将此端口设置为在GAE运行配置和Android应用中使用的端口。如果这样可以解决问题并且您很好奇，那么您可能希望看到已经绑定到端口8888的内容。
  3. 找到一个绝对没有绑定任何东西的端口（1024以上）并在你的GAE运行配置中尝试。
  4. 如果达到这一点，您将无法绑定到任何端口，这很奇怪。如果涉及这个，请回信=）

我遇到了同样的问题：使用eclipse安卓应用引擎连接项目，使用localhost后端在云端点服务器上注册成功，在使用app引擎部署后端的设备上运行时失败。在我的设备上清除缓存3小时并搜索答案后，我做了以下对我有用的工作，现在云端点注册成功，我可以将GCM发送到我的设备。

  1. 右键单击客户端项目＆gt; android工具＆gt;添加支持 文库
  2. 右键单击服务器端项目＆gt;谷歌＆gt;生成云端点客户端库
  3. 从手机中删除应用并清除手机缓存（对于galaxy nexus jelly bean：设置＆gt;存储＆gt;点击缓存数据）
  4. 确保服务器当前未在您的localhost上运行
  5. 因为您刚刚更新了支持库，所以从您的计算机重新安装应用程序

    6. 希望有所帮助!!
