MaterialLibrary is an Open Source Android library that back-port Material Design components to pre-Lollipop Android.
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)
Material Palette is a Material Design Color Palette Generator.
MaterialDesignLibrary is a library with components of Android L to you use in android 2.2
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.

Android uses a new design metaphor inspired by paper and ink that provides a reassuring sense of tactility. Visit the material design site for more resources.
Graphic designers aren't programmers and sometimes don't know how to properly prepare graphic assets for developers. This simple cheatsheet should help them to do their job better, and to simplify developers' lives.
