Android Developer Roadmap 2022 suggests learning paths to understanding Android development. You can read the roadmap following the line path in the middle of the map.

Each node indicates concepts of Android systems, Android SDK, and generally used libraries. It would be helpful to refer to the Android Developers Reference or GitHub for the specific terminologies.

In addition, you don't need to learn everything from this roadmap. So we recommend only reading the sections that would be helpful to you.
