ServerSocket Android

Question

嘿社区我有以下ServerSocket应该监听端口53000并记录任何收到的数据.但是,我似乎无法通过server.accept()阻塞调用.

public void run() {

        SocketServer server = new ServerSocket(53000);


        //---buffer store for the stream---
        byte[] buffer = new byte[1024];
        //---bytes returned from read()---
        int bytes;

        //---keep listening to the InputStream until an
        // exception occurs---
        while (true) {
            try {

                socket = server.accept();
                BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));

                String str = in.readLine();

                Log.i("received response from server", str);

                in.close();
                socket.close();

            } catch (IOException e) {
                Log.e(TAG, e.getMessage());
            } catch (Exception e){
                server.close();
                Log.e(TAG, e.getMessage());
            }
        }

    }

我还在Manifest文件中为应用程序提供了INTERNET权限.()

为了增加这个谜团,我还验证了客户端响应被发送到该端口.

我需要做些什么来使这项工作成功吗？

谢谢.

你的代码非常混乱,甚至无法编译.我做了一些调整,以便我可以测试你的代码,它工作正常.这是我使用的测试应用程序:

package com.test.stackoverflow

import java.io.BufferedReader;

public class ServerSocketTestActivity extends Activity {
    /** Called when the activity is first created. */
    private static String TAG = "ServerSocketTest";

    private ServerSocket server;

    Runnable conn = new Runnable() {
        public void run() {
            try {
                server = new ServerSocket(53000);

                while (true) {
                    Socket socket = server.accept();
                    BufferedReader in = new BufferedReader(
                            new InputStreamReader(socket.getInputStream()));

                    String str = in.readLine();

                    Log.i("received response from server", str);

                    in.close();
                    socket.close();
                }
            } catch (IOException e) {
                Log.e(TAG, e.getMessage());
            } catch (Exception e) {             
                Log.e(TAG, e.getMessage());
            }
        }
    };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        new Thread(conn).start();
    }

    @Override
    protected void onPause() {      
        super.onPause();
        if (server != null) {
            try {
                server.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }   
}

使用此代码和通过adb shell我运行的netcat 能够连接并与应用程序通信.
