Android adopted Gradle as the preferred build automation system a few years ago, but many Android developers are still unfamiliar with this open source tool. This hands-on guide provides a collection of Gradle recipes to help you quickly and easily accomplish the most common build tasks for your Android apps. You’ll learn how to customize project layouts, add dependencies, and generate many different versions of your app.
Gradle is based on Groovy, yet very little knowledge of the JVM language is required for you to get started. Code examples use Android SDK version 23, with emulators from Marshmallow (Android 6) or Lollipop (Android 5). If you’re comfortable with Java and Android, you’re ready.
