Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project. It is much easier to understand a large codebase when all the code in it is in a consistent style.

"Style" covers a lot of ground, from "use camelCase for variable names" to "never use global variables" to "never use exceptions." This project holds the style guidelines we use for Google code. If you are modifying a project that originated at Google, you may be pointed to this page to see the style guides that apply to that project.

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)
