multipart data using Android Volley

I am using Volley for calling web request for my app. But as i am Volley for first time. I just want to know that how to upload image/video media data via volley using multipart.

I searched for it many sites, I got some results over

But, these methods does’nt look good or efficients. So, Please help me that how to upload media data using volley. Or i should not use Volley, and should go for the previous manual approach

Anyway, all thoughts and answers are extremely appreciated. Thank you for your help.
