Carbon

Material Design implementation for Android 4.0 and newer. This is not the exact copy of the Lollipop's API and features. It's a custom implementation of the most useful things as shown in the design specification. Carbon tries to:

make things easier (specify cornerRadius='dp' instead of creating an xml and/or a ViewOutlineProvider)
make it all work and look the same on all APIs (like CheckBox's left padding)
really backport features (don't use gradients for shadows!)
fix Android's everlasting bugs (FrameLayout ignores child's padding when no gravity is set)
