CodePath Android Cliffnotes

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Ever been frustrated finding information on outdated one-off blog posts and tutorials that has since become irrelevant?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 have you been googling only to find your answer on a 2 year old Stack Overflow post? We believe there's got to be a better way. Why not have a community to work together in creating useful and detailed documentation for every aspect of Android development(or any platform)?

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!

We Need Your Help!

We need your help making the guides even better. In particular, here are the easiest ways to contribute:

  1. Update Guides. Review existing guides and update outdated content, add tips or add/update images
  2. Fill Out Guides. Find guides that are simply stubs and fill them out with content.
  3. Create New Guides. Review the missing topics list and create new topic guides.

We maintain a master missing topics list that contains the most important missing topics. Also, look for items in the cliff notes with the Needs Attention mark which indicates the guide needs some love. If you see a topic you'd like added, please check the issues for this repository to let us know.

If you are interested in contributing to our guides, please check out our contribution guidelines first.


These guides were originally created and adapted by Nathan Esquenazi as a part of our CodePath training and bootcamps. We have also had contributions from many community members including:
