Awesome Android AOSP

A collection of Android AOSP system (Android Open Source Project) and ROM development related resources.

This collection does not concern the development of application, there is a awesome list concerning this case at JStumpp/awesome-android.

Inspired by many awesome list like sindresorhus/awesome.

This project is in work in progress !!! Some links may be not valid or not so useful.

Contributions are welcome! I am looking for any kind of information that can help in the development of Android ROM. Don't hesitate to participate to make pull requests and or to exchange in the issues. You can read the contribution guidelines to know how to help me.

English is not my primary language, there might be some language mistakes (feel free to correct them!).

There are also other nice resources references available on this repository :

pages from the official AOSP Android documentation : official_documentation.md
videos from some interesting video channel : channel_videos.md
