Developing applications for the Android mobile operating system can seem daunting, particularly if it requires learning a new programming language: Kotlin, now Android’s official development language. With this practical book, Android developers will learn how to make the transition from Java to Kotlin, including how Kotlin provides a true advantage for gaining control over asynchronous computations. Authors Pierre-Olivier Laurence, Amanda Hinchman-Dominguez, G. Blake Meike, and Mike Dunn explore implementations of the most common tasks in native Android development, and show you how Kotlin can help you solve concurrency problems. With a focus on structured concurrency, a new asynchronous programming paradigm, this book will guide you through one of Kotlin’s most powerful constructs, coroutines. * Learn about Kotlin essentials and the Kotlin Collections Framework * Explore Android fundamentals: the operating system and the application container and its components * Learn about thread safety and how to handle concurrency * Write sequential, asynchronous work at a low cost * Examine structured concurrency with coroutines, and learn how channels make coroutines communicate * Learn how to use flows for asynchronous data processing * Understand performance considerations using Android profiling tools * Use performance optimizations to trim resource consumption
