How animation works on android

I have the floating widget and if I drag it, it turns in to a wand connects to a broom and shoots off like a rocket and a rainbow then appears and says my cache is cleaned. Was just wondering how this works, the animation part.

That would take about 10 months of a CS course in college, if you want a full explanation. If you want a short one, it's part of OpenGL.
