在android两个模拟器中使用套接字的客户端服务器通信

Question

尝试连接两个Android仿真器时出错。

首先我运行Client Emulator 5554然后运行SErver Emulator 5556

另一方CMD我写这个：

telnet localhost 5554
redir add tcp:5000:6000

在客户端单击发送按钮后，我收到错误，没有响应！

我的代码：

服务器

package com.example.socketserver;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends Activity {
    TextView textIn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textIn = (TextView)findViewById(R.id.textView1);
    }

    public void Start(View v) throws IOException{
        Socket socket = null;
        ServerSocket serverSocket = new ServerSocket(6000);

        socket = serverSocket.accept();
        DataInputStream dataInputStream = null;
        dataInputStream = new DataInputStream(socket.getInputStream());
        textIn.setText(dataInputStream.readUTF());
        //Toast.makeText(this, "Listening...", Toast.LENGTH_SHORT).show();
        TextView label=(TextView)findViewById(R.id.textView3);
        label.setText("Loading...");
        serverSocket.close();
        }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

客户端

package com.example.socketclient;

import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;

public class ClientActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_client);
    }

    public void Send(View v) throws IOException{
        Socket socket = null;
        socket = new Socket("10.0.2.2", 5000);
        DataOutputStream dataOutputStream = null;
        dataOutputStream = new DataOutputStream(socket.getOutputStream());
        dataOutputStream.writeUTF("Message from Sender");

        if (socket != null){
        socket.close();
        }
        }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.client, menu);
        return true;
    }

}
