Android : Complete working code to send json from android and handle it using django

I am a beginner in android as well as django. I need to sample working code to send JSON object from my android app and handle it on Django, backend server. Then i need to send the result json from Django to my android application.

I have gone through many tutorials and tried many solutions but i couldn't make my code working. So it would be very kind if someone send me a working code for both android and django to send and receive JSON object.

Thanks in advance. This will help me a lot.
