[Q]Adding animations in apps (App development)

Hi,
I'm developing a kitkat ROM for a Mediatek powered device. I want to add some animations in settings app (android_packages_apps_settings). But I'm new to these things (app development) and I'm not sure where and how to apply the animations. I want to add this animation(reveal effect): http://developer.android.com/trainin...ns.html#Reveal
If there are any guides around here then please redirect me to it.
