i. What You Need

Written by Victoria Gonda

To follow along with this book, you’ll need the following:

• An Android device: While it is possible to follow along using an emulator, emulators don’t support all accessibility features and the features they do support can be challenging to use.
• Kotlin 1.6 or later: This book uses Kotlin 1.6 throughout. The examples may work with an earlier version of Kotlin, but they are untested.
• Android Studio Chipmunk or later: Android Studio is the main development tool for Android. You’ll need Android Studio Chipmunk or later for the tasks in this book. You can download the latest version of Android Studio from Android’s developer site here: https://developer.android.com/studio.

If you haven’t installed the latest version of Android Studio, be sure to do that before continuing with the book. The code covered in this book depends on Android 12, Kotlin 1.6 and Android Studio Chipmunk — you may get lost if you try to work with an older version.
