The goal of this project is to provide a hand-picked collection of Android libraries, tools, open-source projects, books, blogs, tutorials - you name it.

This project will try to showcase only the best, most popular and well-tested resources that you will actually need and find useful rather than overwhelming you with a plethora of low-quality ones.

Happy learning. :+1:
