【Android】socket通信

在用安卓手机做socket通信的时候，出现这个报错 java.net.SocketException: socket failed: EACCES (Permission denied)，以后不用看就知道网络权限没有加。
服务端代码如下：

public class SocketServer {
    public static void main(String[] args) throws IOException {
        //1.创建一个服务器端Socket，即ServerSocket，指定绑定的端口，并监听此端口
        ServerSocket serverSocket = new ServerSocket(12345);
        InetAddress address = InetAddress.getLocalHost();
        String ip = address.getHostAddress();
        Socket socket = null;
        //2.调用accept()等待客户端连接
        System.out.println("~~~服务端已就绪，等待客户端接入~，服务端ip地址: " + ip);
        socket = serverSocket.accept();
        //3.连接后获取输入流，读取客户端信息
        InputStream is=null;
        InputStreamReader isr=null;
        BufferedReader br=null;
        OutputStream os=null;
        PrintWriter pw=null;
        is = socket.getInputStream();     //获取输入流
        isr = new InputStreamReader(is,"UTF-8");
        br = new BufferedReader(isr);
        String info = null;
        while((info=br.readLine())!=null){
            //循环读取客户端的信息
            System.out.println("客户端发送过来的信息" + info);
        }
        socket.shutdownInput();//关闭输入流
        socket.close();
  }

客户端代码如下：我跑在安卓手机上

 private void acceptServer() throws IOException {
        //1.创建客户端Socket，指定服务器地址和端口
        Socket socket = new Socket("xxx", 12345);
        //2.获取输出流，向服务器端发送信息
        OutputStream os = socket.getOutputStream();//字节输出流
        PrintWriter pw = new PrintWriter(os);//将输出流包装为打印流
        //获取客户端的IP地址
        InetAddress address = InetAddress.getLocalHost();
        String ip = address.getHostAddress();
        pw.write("客户端：~" + ip + "~ 接入服务器！！");
        pw.flush();
        socket.shutdownOutput();//关闭输出流
        socket.close();
    }

xxx替换为自己的服务器的ip,保证手机和服务器在同一个网段即可。
