How to Build Android Applications with Kotlin: A hands-on guide to developing, testing, and publishing production-grade Android 16 apps

Written by four veteran developers with 60+ years of collective experience, this updated third edition will jumpstart your Android development journey, focusing on Kotlin libraries and Jetpack Compose, Google’s powerful declarative UI framework. You’ll learn the fundamentals of app development, enabling you to use Android Studio, as well as get to grips with Jetpack Compose to create your first screens, build apps to run them on virtual devices through guided exercises, and implement Jetpack Compose’s layout groups to make the most of lists, images, and maps. The book has been updated with Kotlin’s powerful networking and coroutines libraries to help you fetch data in the background from a web service and manage displaying the data using Kotlin flows. You’ll learn about testing, creating clean architecture, and persisting data, as well as exploring the dependency injection pattern and learning how to publish your apps on the Google Play Store. You'll also work on realistic projects split up into bite-size exercises and activities, along with building apps to create quizzes, read news articles, check weather reports, store recipes, retrieve movie information, and remind you where you parked your car. By the end of this book, you'll have gained the skills and confidence to build your own creative Android apps using Kotlin.
