我在我的项目中包含了一个套接字，它运行良好。 我的服务器收到了我的请求，我的应用程序收到了答案。 除了垃圾收集器之外，几乎所有权利都开始循环并且没有停止。
我之前杀死了所有 Intent (包括调用套接字的 Intent )，我尝试了socket.disconnect，我关闭了我的应用程序(并且GC仍在运行)但没有工作。
如果我再次运行我的应用程序或在配置中强制停止，GC 就会停止。

我需要做什么来停止这个 GC 循环？它消耗大量电池。
感谢和问候。
更新
我正在使用这个套接字库。
2014 年 2 月 4 日更新
经过一番测试，我找到了线索。 socket.disconnect 方法导致了我的应用程序中的循环，现在我遇到了另一个问题。
我该怎么办？如果我执行方法socket.disconnect，GC将无限运行，如果我不使用socket.disconnect，应用程序将保持套接字打开并工作，并且会消耗大量电池。
2014 年 2 月 6 日更新
我仍然没有解决这个问题，但是我在 Github 上阅读了 SocketIO 的问题，我看到很多开发人员都有同样的错误，直到今天问题仍然存在。
SocketIO 项目问题的链接在这里:Issues Project SocketIO
最佳答案
在 Android 中调用 socket.disconnect() 时，我遇到了同样的问题。
修复方法如下。
从https://github.com/Gottox/socket.io-java-client查看socket.io-java-client项目;
下载Java-WebSocket-1.3.0.jar；
将socket.io项目lib文件中的WebSocket.jar替换为java-websocket-1.3.0.jar；
使用ant构建socket.io-java-client到jar；
然后将 socketio.jar 替换为您刚刚构建的新的。
希望这有帮助。
