Simple example of Android client interacting with server data using HttpURLConnection doGet

//Android client sends request
String strUrl="http://192.168.191.1:8080/trial/LoginServlet";		
String result = null;
String readLine = null;
URL url1 = new URL(strUrl);
HttpURLConnection urlConn = (HttpURLConnection)url1.openConnection();			
InputStreamReader in = new InputStreamReader(urlConn.getInputStream());
BufferedReader bufferReader = new BufferedReader(in);
while((readLine = bufferReader.readLine()) != null){
	result += readLine;
}
in.close();
urlConn.disconnect();

//The server receives the request
package servlet;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io. *;

public class LoginServlet extends HttpServlet
{
    protected void doGet(HttpServletRequest request,
           HttpServletResponse response) throws ServletException,IOException{
    response.getOutputStream().print("admin");
 }
}
