Kotlin Programming for Android.

The book is devoted to developing mobile applications for Android using the Kotlin language. The main structures and elements of the language are reviewed, and the Kotlin collections framework is described in detail. The architecture of the Android operating system, applications, and their containers is presented, and the basics of parallel programming are studied. It discusses thread safety and working with concurrency using callbacks. A separate chapter is devoted to Kotlin's special constructs—coroutines—with an emphasis on structured concurrency. Channels and the use of flows for asynchronous data processing are examined. The book covers improving application performance using Android profiling tools and reducing resource consumption through performance optimization.
