i. What You Need

To follow along with this book, you need:

  • Android Studio 4.1+: Available at https://developer.android.com/studio/. This is the environment in which you’ll develop most of the sample code in this book. If you didn’t install it already, now is the right time to do that!
  • Java SE Development Kit 8+: Most of the code in this book will be run on the Java Virtual Machine or JVM, for which you need a Java Development Kit or JDK. The JDK can be downloaded from Oracle at http://www.oracle.com/technetwork/java/javase/downloads/index.html.
  • Kotlin Playground: You can also use the Kotlin Playground available at the Kotlin home page at https://play.kotlinlang.org.
  • Android 6.0+: The minimumSdkVersion for the projects targets API 23. Therefore, you need an emulator or device running API 23 or higher.
