Prerequisites

This book is targeted at developers starting out with Android app development.

You will want another educational resource to go along with this book. The book will cross-reference Elements of Android Jetpack, but you can use other programming guides as well. This book shows you each step for building an app, but you will need to turn to other resources for answers to questions like “why do we need to do X?” or “what other options do we have than Y?”.

The app that you will build will be written in Kotlin, so you will need to have a bit of familiarity with that language. Elements of Kotlin covers this language and will be cross-referenced in a few places in this book.

Also, the app that you will create in this book works on Android 5.0+ devices and emulators. You will either need a suitable device or be in position to use the Android SDK emulator in order to build and run the app.
