android socket客户端app

连接来自java写的服务器，连接成功后在textview中输出“连接服务器成功！”

服务器端：

import java.io.*;import java.net.*;public class MyServer {    public static void main(String[] args) throws IOException {        ServerSocket ss = new ServerSocket(30000);        while(true) {            Socket s = ss.accept();            PrintStream ps = new PrintStream(s.getOutputStream());            ps.println("连接服务器成功！");            ps.close();            s.close();        }    }}

客户端：

最终目标是要写个tcp调试助手的。
