Nobody is using these libraries in B4A. Atleast I havent seen any UX intense apps in B4A leads me to believe i would waste time in wrapping it when nobody is using it.It will be great if we could implement the parallax scrolling effect that is present throughout Lollipop. I had requested for a wrapper. Please take a look.
