Welcome to the open-source Codepath Android Cliffnotes! Our goal is to become the central crowdsourced resource for complete and up-to-date Android content and tutorials. Just take me to the notes!
We have guides for everyone whether you are beginner, intermediate or advanced. Want to learn how to use the ActionBar or the ins and outs of fragments? We got that. Want to learn about testing or how to build flexible user interfaces for multiple devices? We got you covered. We don't waste time with the "theoretical approach" you might get from a book. We cover exactly the things we use every day as we are developing apps for contracts.
