我已经使用下面的这段代码设置了我的 webview 的代理:
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); 上设置了一个断点；而且它永远不会击中它

我错过了什么吗？
ServerSocket 在运行 webview 的同一个 android 应用程序中运行，其想法是重定向所有 http 请求以通过我的套接字服务器代理。
谢谢
编辑:我调试了代理代码，它失败并抛出这个异常
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()
它发生在我调用 setProxy 时。
有什么建议吗？
最佳答案
错误告诉您:无法在尚未调用 Looper.prepare() 的线程内创建处理程序
您需要在实现 Looper 的线程中执行代码。
Can't create handler inside thread that has not called Looper.prepare()
Can't create handler inside thread which has not called Looper.prepare()
