title: android-send username and get details as json object from http server
body: <p>In my login page, I have to send the username to http server and fetch user details like name,number,etc as json object. I am new to network connection and json.  I know there are plenty of examples out there but could someone point me to an actual tutorial? I'm looking for a step by step process with code and explanation of why you do each step, or of what that step does. It doesn't need to be a complex, simple will suffice.</p>
