title: Android faster download of files with Multi thread
body: <p>I'm working on an app that requires downloading of big video files (300-500MB).<br>
  I would like to know if there's a way to speed up the download of a single file using multi-threading.<br>
  I've saw this type of implementation on applications like TubeMate, but I clueless about the code used to achieve it.<br>
  I don't need you to code for me :) I just need a starting point, like an article or tutorial about this, tks.</p>
