Android tcp client (Send data from client and get server response) - II

This example show the interactive action between server and client.
1. tcpserver : Add print c.recv(1024) before send response in server side as follows
#!/usr/bin/python           # This is server.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   print c.recv(1024)
   c.send('Thank you for connecting')
   c.close()                # Close the connection  

2. tcpclient: Add send data before get response from server side.
Socket socket = null;

            try {
                socket = new Socket(dstAddress, dstPort);

                ByteArrayOutputStream byteArrayOutputStream =
                        new ByteArrayOutputStream(1024);
                byte[] buffer = new byte[1024];

                int bytesRead;
                DataOutputStream DOS = new DataOutputStream(socket.getOutputStream());
                DOS.writeUTF("手機送出訊息");
                InputStream inputStream = socket.getInputStream();

    /*
     * notice:
     * inputStream.read() will block if no data return
     */
                while ((bytesRead = inputStream.read(buffer)) != -1){
                    byteArrayOutputStream.write(buffer, 0, bytesRead);
                    response += byteArrayOutputStream.toString("UTF-8");
                }

            } catch (UnknownHostException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                response = "UnknownHostException: " + e.toString();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                response = "IOException: " + e.toString();
            }finally{
                if(socket != null){
                    try {
                        socket.close();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
