[Q] How to add Lollipo Easter Egg in Kitkat Roms topic

Hey guys can you help me how to add Lollipop Easter Egg in my Rom?

I already read the Guide how to add Easter Egg by @Droidbuster
but the problem is i cant find the PlatLogoActivity.smali

I already decompile my framework.jar
but there`s no smali/com/android/internal/app
and open PlatLogoActivity.smali in it. Only smali/android/ and a bunch of folders like accessibilityservice, accounts, animation, annotation, app(i look in there but theres no PlatLogoActivity.smali), etc

Guys! Please Help me. Noob Here :(
