Question

我使用以下代码片段设置了我的webview代理：

ProxySettings.setProxy(mContext, "http://127.0.0.1", PORT);

这是我的套接字服务器监听器

serverSocket = new ServerSocket(PORT);
thread = new Thread(runnable, this.getClass().getSimpleName());


public void startlistener() {
        listening = true;
        thread.start();

    }

private Runnable runnable = new Runnable() {

        @Override
        public void run() {
            while (listening) {
                try {
                    Socket accept = serverSocket.accept();

                    String data = getData(accept);

                    httpHandler.handleRequest(data);

                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }

        }
    };

我在String data = getData（accept）上放了一个断点;并且从未打过它

我错过了什么吗？

ServerSocket运行在运行webview的同一个Android应用程序中，其目的是将所有http请求重定向到我的套接字服务器代理。

由于

编辑：我调试了代理代码并且失败并抛出此异常

07-01 15:44:02.894: E/GAEProxy.ProxySettings(11267): error setting up webkit proxying = java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

当我调用setProxy时会发生这种情况。

有什么建议吗？

Answer 1

错误告诉你：无法在未调用Looper.prepare（）的线程内创建处理程序

您需要在实现Looper的线程内执行代码。

Can't create handler inside thread that has not called Looper.prepare()

Can't create handler inside thread that has not called Looper.prepare() inside AsyncTask for ProgressDialog

Can't create handler inside thread which has not called Looper.prepare()

Answer 2

如果您的应用程序未使用系统签名进行签名，则无法以编程方式设置代理。 How can you set the http proxy programatically?

webview没有命中服务器套接字代理
