Developing applications for the Android mobile operating system can seem daunting, particularly if it requires learning a new programming language: Kotlin, now Android??s officialdevelopment 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 FrameworkExplore Android fundamentals: the operating system and the application container and its componentsLearn about thread safety and how to handle concurrencyWrite sequential, asynchronous work at a low costExamine structured concurrency with coroutines, and learn how channels make coroutines communicateLearn how to use flows for asynchronous data processingUnderstand performance considerations using Android profiling toolsUse performance optimizations to trim resource consumption
