What is it?
Vectoroid provides Vector graphics functionality in a standard Android View. It is a library - NOT an app. You can also use it for animations, or just about anything you can think of.
A large part of Vectoroid is open-source, drawings can be shared, reused and remixed easily.
It is designed with similarities to the google.MapView and android.WebView components, you can design your own UX/Interface on top.
