推荐答案

任何连接到网络的设备都将通过它们的 IP 和端口/套接字进行通信.通过 telnet 或套接字连接并将数据写入其套接字缓冲区的最简单方法.

Any device connected to a network will communicate via their IP and Ports / sockets. The simplest way to connect via telnet or socket and write the data to their socket buffers.

try 
    {
    Socket sock = new Socket("192.168.1.222", 9100);
    PrintWriter oStream = new PrintWriter(sock.getOutputStream());
        oStream.println("HI,test from Android Device");
        oStream.println("


");
        oStream.close();
        sock.close(); 
    }
    catch (UnknownHostException e) 
    {
        e.printStackTrace();
    } 
    catch (IOException e) 
    { 
        e.printStackTrace();
    }
