Preface

Thanks!

First, thanks for your interest in Android app development! Android is the world’s most popular operating system, but its value comes from apps written by developers like you.

Also, thanks for your interest in this book! Hopefully, it can help “spin you up” on how to create Android applications that meet your needs and those of your users.

And thanks for your interest in CommonsWare! The Warescription program makes this book and others available, to help developers like you craft the apps that your users need.

How the Book Is Structured

Many books — such as Elements of Android Jetpack, — present programming topics, showing you how to use different APIs, tools, and so on.

This book is different.

This book has you build an app from the beginning. Whereas traditional programming guides are focused on breadth and depth, this book is focused on being “hands-on”, guiding you through the steps to build the app. It provides some details on the underlying concepts, but it relies on other resources — such as Elements of Android Jetpack — for the full explanation of those details. Instead, this book provides step-by-step instructions for building the app.

If you are the sort of person who “learns by doing”, then this book is for you!
