Where to find free open sourced android custom controls?

Question

I'm looking for some site/library/project with advanced custom Android controls? if you know one, are they free and open sourced?

Answer 1

Take a look at commonsguy github repository. You can find several quite interesting android components there, all with source code available under Apache License

Answer 2

android-arsenal.com has a few controls, utilities and scripts; it's a mixed bag but it's the closest thing I've seen to a controls website.
