Android进阶篇-Socket通信

http://www.cnblogs.com/gongcb/archive/2012/05/17/2506839.html

Socket通信作为一种重要的数据交互方式，在Android开发过程也十分重要。

//TCP Socket服务端

            ServerSocket serverSocket = null;                        try {                //4567 ServerSocket端口号                serverSocket = new ServerSocket(4567);                //服务端接受客户端的Socket请求                Socket socket = serverSocket.accept();                //获取输入流                InputStream inputStream = socket.getInputStream();                byte buffer[] = new byte[4*1024];                int temp = 0;                //将InputStream数据读入到Buffer中                while((temp = inputStream.read(buffer)) != -1){                                    }            } catch (Exception e) {                // TODO: handle exception                e.printStackTrace();            }

客户端：

            try {                Socket socket = new Socket("192.168.0.104", 4567);                InputStream inputStream = new FileInputStream("f://file/word.txt");                OutputStream outputStream = socket.getOutputStream();                byte buffer[] = new byte[4*1024];                int temp = 0;                while((temp = inputStream.read(buffer)) != -1){                    outputStream.write(buffer, 0, temp);                }            } catch (UnknownHostException e) {                // TODO Auto-generated catch block                e.printStackTrace();            } catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }

UDP Socket服务端：

            try {                DatagramSocket datagramSocket = new DatagramSocket(4567);                byte data[] = new byte[4*1024];                DatagramPacket datagramPacket = new DatagramPacket(data, data.length);                datagramSocket.receive(datagramPacket);            } catch (Exception e) {                // TODO: handle exception            }

客户端：

            try {                DatagramSocket socket = new DatagramSocket(4567);                InetAddress inetAddress = InetAddress.getByName("192.168.0.104");                String helloWorld = "helloworld";                byte[]  data = helloWorld.getBytes();                DatagramPacket datagramPacket = new DatagramPacket(data, data.length, inetAddress,4567);                socket.send(datagramPacket);             } catch (Exception e) {                // TODO: handle exception            }
