Next chapter: Chapter 2 : Observers

This chapter is a small part of a biggest training project, you can find on Github. You’ll have the main branch with the answers/responses/unit tests and documentation. You could start with the “questions” branch to only have the questions.

You’ll have the full table of content of the articles on Medium.

You can download the book on Android2ee
