Android's Architecture Components (Final Version)

This book dives deep into the Architecture Components, showing you how they work individually and in concert. With over a dozen sample projects, the book covers much of what blog posts miss, in terms of how to make this library work in practice.
Android app development can be divided into two generations:
• First-generation app development uses Java as the programming language and leverages the Android Support Library and the android.arch edition of the Architecture Components
• Second-generation app development more often uses Kotlin as the programming language and leverages AndroidX and the rest of Jetpack (which includes an AndroidX edition of the Architecture Components)
This book is a first-generation book. It explores the android.arch edition of the Architecture Components and it uses Java for most of the examples.
Second-generation material can be found in CommonsWare’s “Elements” book series. Of particular note, some introductory Architecture Components material can be found in Elements of Android Jetpack.
I am in the process of wrapping up my books that focused on the first generation of Android app development (Java and the Android Support Library), in favor of books focusing on the second generation (Kotlin and Jetpack/AndroidX). The first of the original books to be marked “FINAL” is Android’s Architecture Components.
