editing – Edit host file – Nvidia shield pro

I am trying to edit my host file in nvidia shield pro device. Its not rooted and I get read only error when I try to update the host file using adb push. I am a newbie in this. I need to do some url redirecting.

I am not trying to block anything. I have a local Apache server set up and want to redirect the traffic from the shield to my local server for some custom urls.
