当我用插座垃圾收集循环 [英] Garbage Collector looping when I use socket
问题描述
我包括我的项目一个插座，它的工作好。 我的服务器收到了我的请求，我的应用程序接收到的答案。 几乎一切权利，除了垃圾收集器开始一个循环，并没有停下来。
I'm including a socket in my project and it's working good. My server received my request and my app received the answer. Almost everything right except for the garbage collector start a looping and didn't stop.
我之前（包括谁被称为插座的意图），杀死了所有的意图，我试过socket.disconnect，我闭上我的应用程序（和GC仍在运行），但没有奏效。
I killed all the intents before (including the intent who called the socket), I tried the socket.disconnect, I closed my application (and the GC still running) but didn't work.
在GC只是停止，如果我再次运行我的应用程序或强制停止的配置。
The GC just stops if I Run my app again or force stop in the configurations.

我需要做些什么来阻止这种GC循环？它消耗了大量的电池。
What I need to do to stop this GC looping? It's consuming a lot of battery.
感谢和问候。
更新
我用这个socket库。
I'm using this socket library.
更新2014年2月4日
一些测试后，我发现了一个线索。 socket.disconnect造成循环在我的应用程序和方法，现在我有另外一个问题。
After some tests, I found a clue. The method socket.disconnect caused the looping in my application and now I'm with another problem.
我应该怎么办？如果我执行的方法socket.disconnect GC将运行无限，如果我不使用socket.disconnect应用程序将留在打开和工作，会大量消耗电池的插槽。
What should I do? If I execute the method socket.disconnect the GC will run infinitely and if I don't use the socket.disconnect the application will stay with the socket opened and working and will consume a lot of battery.
更新2014年2月6日
我还没有解决这个问题，但我读SocketIO的问题GitHub上，我看到了很多的开发者提供了同样的错误，并直到今天问题仍然存在。
I still have not solved this question but I read the issues of SocketIO on github and I saw a lot of developers with the same error and until today the problem continues.
链接SocketIO项目的问题是在这里：的问题项目SocketIO

推荐答案
我在Android中调用socket.disconnect时有同样的问题（）。
I had the same issue in Android when calling the socket.disconnect().
下面是它是如何固定的。
Here is how it was fixed.
从 https://github.com结帐socket.io-Java的客户端项目/Gottox/socket.io-java-client ;
下载Java-的WebSocket-1.3.0.jar;
Download the Java-WebSocket-1.3.0.jar;
替换WebSocket.jar在socket.io项目的Java的WebSocket-1.3.0.jar的库文件;
Replace the WebSocket.jar in the lib file of socket.io project with java-websocket-1.3.0.jar;
使用Ant来构建的socket.io-Java的客户端罐;
Use ant to build the socket.io-java-client to jar;
然后用新的，你只是建立更换socketio.jar。
Then replace the socketio.jar with the new one you just build.
希望这有助于。
