Font Awesome gives you scalable vector icons that can instantly be customized - size, color, drop shadow, and anything that can be done with the power of CSS.
Open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products.
material-design-icons are the official open-source icons featured in the Google Material Design specification.
RxJava is a Java VM implementation of Reactive Extensions: a library for composing asynchronous and event-based programs by using observable sequences.
It extends the observer pattern to support sequences of data/events and adds operators that allow you to compose sequences together declaratively while abstracting away concerns about things like low-level threading, synchronization, thread-safety and concurrent data structures.

The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.
A simple charting library for Android, supporting line- bar- and piecharts, scaling, dragging and selecting.
ZXing ("zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java, with ports to other languages.
Glide is fast and efficient image loading library for Android that wraps image downloading, resizing, memory and disk caching, and bitmap recycling into one simple and easy to use interface. By default, Glide includes an implementation for fetching images over http based on Google's Volley project for fast, parallelized network operations on Android.
100% interoperable with Java™
ButterKnife is a view "injection" library for Android which uses annotation processing to generate boilerplate code for you.

For the first time, designers can create and ship beautiful animations without an engineer painstakingly recreating it by hand.
Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.
This project aims to provide a reusable instrument for asynchronous image loading, caching and displaying.
Android optimized event bus that simplifies communication between Activities, Fragments, Threads, Services, etc. Less code, better quality.
libGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, Mac OS X, Android, your WebGL enabled browser and iOS.
Godot is a fully featured game engine. It focuses on having great tools, and a visual oriented workflow that can export to PC, Mobile and Web platforms with no hassle. The editor, language and APIs are feature rich, yet simple to learn, allowing you to become productive in a matter of hours.
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.
An open source software framework. It can be used to build games, apps and other cross platform GUI based interactive programs.
A powerful image downloading and caching library for Android.
Android specific bindings for RxJava.
This module adds a number of classes to RxJava that make writing reactive components in Android applications easy and hassle free.
Parse is a complete technology stack to power your app's backend.
Fresco is a powerful system for displaying images in Android applications.
Fresco takes care of image loading and display, so you don't have to. It will load images from the network, local storage, or local resources, and display a placeholder until the image has arrived. It has two levels of cache; one in memory and another in internal storage.
