VB写的服务端，android写的客户端，在模拟器上能通信，把android客户端按到手机上就不连接不上了，小弟是菜鸟，正在学习android的scoket通信
客户端程序：
package wyf.wpf;//声明包语句
import java.io.DataInputStream;//引入相关类
import java.io.DataOutputStream;
import java.io.Flushable;
import java.io.IOException;
import java.io.PrintWriter;

import java.net.Socket;//引入相关类
import android.app.Activity;//引入相关类
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.os.Bundle;//引入相关类
import android.view.View;
import android.widget.Button;
import android.widget.EditText;//引入相关类
public class Sample_10_1_Client extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);//设置当前屏幕

button4.setOnClickListener(new buttonListener4());
button5.setOnClickListener(new buttonListener5());
connectToServer();//连接服务端
}
class buttonListener1 implements OnClickListener, android.view.View.OnClickListener{

try{

//msg = new PrintWriter(socket.getOutputStream());
din = new DataInputStream(socket.getInputStream());//获得DataInputStream对象
dout = new DataOutputStream(socket.getOutputStream());//获得DataInputStream对象
//din.read(msg.getBytes("UTF-8"));//getBytes("UTF-8")
//msg = din.readUTF(); //读取服务端发来的消息
//et.setText(msg);//设置EditText对象\
//button1.setText(msg);

}
}
[解决办法]
两步就可以了：
步骤：
1、打开百度搜索“IP查询”，然后会有一个本机IP: xx.xx.xx.xx
2、将以下代码中的127.0.0.1改成步骤1查到的本机IP：xx.xx.xx.xx
socket = new Socket("127.0.0.1", 9958);
[解决办法]
socket = new Socket("127.0.0.1", 9958);//创建Socket对象 10.200.53.56 60.213.232.43
不是这个9958端口，把这个port转化为16进制，再交换高低位。
即：port = ((port& 0xFF00)>>8)|(port& 0x00FF)<<8);
