Question

当我使用Windows运行eclipse Android模拟器来连接套接字时，它很成功。但是，当我使用Mac os Lion运行“相同”代码时，模拟器显示“不幸的是客户端测试停止!!“请帮我解决这个问题。我已经将权限添加到互联网上了！

package com.example.testclientokok;

import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

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

public class MainActivity extends Activity {

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    try {
        Socket socket=new Socket(InetAddress.getLocalHost(), 8888);
    } catch (UnknownHostException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
}

服务器部分

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


public class MyServer {

 public static void main(String[] args){
 ServerSocket serverSocket = null;
 Socket socket = null;
 DataInputStream dataInputStream = null;
 DataOutputStream dataOutputStream = null;

 try {
  serverSocket = new ServerSocket(8888);
  System.out.println("Listening :8888");
 } catch (IOException e) {
 // TODO Auto-generated catch block
  e.printStackTrace();
}

while(true){
  try {
   socket = serverSocket.accept();
   dataInputStream = new DataInputStream(socket.getInputStream());
   dataOutputStream = new DataOutputStream(socket.getOutputStream());
   System.out.println("ip: " + socket.getInetAddress());
   System.out.println("message: " + dataInputStream.readUTF());
   dataOutputStream.writeUTF("Hello!");
  } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
  finally{
   if( socket!= null){
    try {
      socket.close();
    } catch (IOException e) {
    // TODO Auto-generated catch block
   e.printStackTrace();
 }
}

if( dataInputStream!= null){
 try {
  dataInputStream.close();
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
}

if( dataOutputStream!= null){
 try {
  dataOutputStream.close();
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
     }
    }
   }
  }
 }
}

如果我理解正确，您正在计算机上执行MyServer，您也可以在其中运行模拟器。如果模拟器中运行的Activity想要与MyServer建立连接，那么它应该使用以下IP地址： 10.0.2.2 （而不是localhost，它引用emualor loopback接口）。
