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" from a book. We cover exactly the things we use every day as we are developing apps for contracts.

Need Help? Please join the google groups for these guides where you can post related questions.

Ever been frustrated finding information on outdated one-off blog posts and tutorials that has since become irrelevant? How many times were you googling only to find your answer only on a 2 year old StackOverflow post? We believe there's got to be a better way. Why not have the community work together to create useful and detailed documentation for every aspect of Android (or any platform)? There's absolutely no reason that we should have to make do with outdated, vague or un-editable content anymore.

Read about our mission to change the way engineers learn new technologies and we would love for you to get involved! In addition, we are a fledgling startup so if you like this guide and what we are trying to do, please consider following us on twitter @codepath!
