程序只实现了连接功能，使用控制台能成功运行，一用进android就出问题了，我知道肯定哪里错了

package com.example.android4_0;



import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.io.PrintWriter;

import java.net.Socket;

import java.net.UnknownHostException;



import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;



public class MainActivity extends Activity {  

    static Socket server;

    private Button button;  

    /** Called when the activity is first created. */  

    @Override  

    public void onCreate(Bundle savedInstanceState) {  

        super.onCreate(savedInstanceState);  

        setContentView(R.layout.activity_main);  

        button = (Button)findViewById(R.id.button1);  

        button.setOnClickListener(new OnClickListener() {  

            @Override  

            public void onClick(View v) {  

	            try {

					server = new Socket("115.28.79.163",32906);

					//定义一个本地地址端口1234的socket

	        		BufferedReader read = new BufferedReader(new InputStreamReader(server.getInputStream()));

	                //注意，使用此方法接收信息，发送的消息必须以“\r\n”结尾，利用BufferedReader实现数据的快速接收,getInputStream()获取socket底层数据输入流，InputStreamReader()实现字节到字符串的高校读取

	                BufferedWriter send =new BufferedWriter(new OutputStreamWriter(server.getOutputStream()));

	                //利用BufferedWriter实现数据的快速写入，getOutputStream()获取socket底层数据输出流，OutputStreamWriter()实现字节到字符串的高校写入	

	                send.write("1\r\n");//服务器识别代号，表示自己的身份

	        		send.flush();//使服务器马上收到消息

	        		String str = read.readLine();//此方法为阻塞状态，一直到收到回车(\r)换行(\n)才结束阻塞(接收信息完毕)\

	        		System.out.println(str);//将受到的信息打印出来

	            } catch (UnknownHostException e) {

					// TODO Auto-generated catch block

					e.printStackTrace();

				} catch (IOException e) {

					// TODO Auto-generated catch block

					e.printStackTrace();

				}

            }  

        });  

    }  

}

xml：

<?xml version="1.0" encoding="utf-8"?>

    android:orientation="vertical" android:layout_width="fill_parent"
