Elements of Android Jetpack

After a decade’s worth of Android app development, 2018 debuted the second generation of Android app development techniques, highlighted by Jetpack and the AndroidX family of libraries.

This book follows in the footsteps of The Busy Coder’s Guide to Android Development, to introduce developers to Android app development, focusing on Jetpack. Here you will learn how to set up an Android app for Java or Kotlin, create a user interface, and more!

In particular, it covers Android through Android 11, plus it covers Android Studio 4.1.1.

This book is published in PDF, EPUB, and MOBI/Kindle formats, for use in your favorite digital book reader. Or, read directly in your Web browser on the Warescription site, complete with full-text searching.

This book will be updated a few times per year, usually after an Android Studio major release.
