============问题描述============
package com.example.udpclient;

import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;

public class MainActivity extends Activity

private static final int MAX_DATA_PACKET_LENGTH = 100;
private byte[] buffer = new byte[MAX_DATA_PACKET_LENGTH];
private DatagramPacket dataPacket = null;
private DatagramSocket udpSocket = null;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread thread = new Thread(runnable);
thread.start();
}
Runnable runnable = new Runnable()
{
@Override
public void run()
{
// TODO Auto-generated method stub
try
{
udpSocket = new DatagramSocket(5000);
dataPacket = new DatagramPacket(buffer, MAX_DATA_PACKET_LENGTH);
Log.v("packet", "pakcet built!");
String str = "hello,jdh"; //这是要传输的数据
byte out [] = new byte[]{(byte)127, (byte)17, (byte)10}; //把传输内容分解成字节
dataPacket.setData(out);
dataPacket.setLength(out.length);
Log.v("packet length", "pakcet length!");
try
{
dataPacket.setAddress(InetAddress.getByName("10.13.33.136"));
dataPacket.setPort(5000);
Log.v("packet port", "pakcet port!");
} catch (UnknownHostException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (SocketException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
try
{
udpSocket.send(dataPacket);
Log.v("packet sent", "packet sent!");
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
}
电脑写的客户端可以发送给服务器，但是手机端这个客户端却发送不成功，10.13.33.136是我本机ip，我手机连的是wifi。求解，是不是手机端写的哪里有问题？谢啦！
