Android Socket开发

突然想到将用windows的程序控制Android程序，就像到了使用socket编程。

下面是android端的程序

 

import android.os.Handler;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
import android.widget.Toast;

import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import java.net.ServerSocket;
import java.net.Socket;

         ConnectStatusText.setText("连接状态: 未连接");

                 // 消息处理
