android 模拟器和电脑服务器端用socket通讯

之前一直会用sockets来实现emulator和PC进行通讯，卡了几天，最后请教其他人终于可以连接了。  错误原因是在IP和端口，IP要用本机IP(在CMD输入ipconfig，注意：每次开机本机IP都不同，ADSL是动态IP)，端口用emulator的名称，5554或5556.java sever文件要另外建java工程运行，在android工程运行不了java(run application)

客户端代码：

while (true)

{

//接受客户端请求

Socket client = serverSocket.accept();

try

{

//接收客户端消息

BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));

String str = in.readLine();

System.out.println("read:" + str);

//向服务器发送消息

PrintWriter out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(client.getOutputStream())),true);

out.println("server message");

//关闭流

out.close();

in.close();

}

catch (Exception e)

{

System.out.println(e.getMessage());

e.printStackTrace();

}

finally

{

//关闭

client.close();

System.out.println("close");

}

}

}

catch (Exception e)

{

System.out.println(e.getMessage());

}

}

//main函数，开启服务器

public static void main(String a[])

{

Thread desktopServerThread = new Thread(new Server());

desktopServerThread.start();

}

}
