Learning Concurrency in Kotlin

By: Miguel Angel Castiblanco Torres

Overview of this book

Kotlin is a modern and statically typed programming language with support for concurrency. Complete with detailed explanations of essential concepts, practical examples and self-assessment questions, Learning Concurrency in Kotlin addresses the unique challenges in design and implementation of concurrent code. This practical guide will help you to build distributed and scalable applications using Kotlin. Beginning with an introduction to Kotlin's coroutines, you’ll learn how to write concurrent code and understand the fundamental concepts needed to write multithreaded software in Kotlin. You'll explore how to communicate between and synchronize your threads and coroutines to write collaborative asynchronous applications. You'll also learn how to handle errors and exceptions, as well as how to work with a multicore processor to run several programs in parallel. In addition to this, you’ll delve into how coroutines work with each other. Finally, you’ll be able to build an Android application such as an RSS reader by putting your knowledge into practice. By the end of this book, you’ll have learned techniques and skills to write optimized code and multithread applications.

Debugging

Often, you will find yourself debugging errors that happen inside a coroutine. Even when you have the steps to recreate a bug, following the code and making sense of what's happening may require some hard debugging work. In this section, we will cover good practices to debug your concurrent code, and I am sure that they will come in handy sometime.

Identifying a coroutine in the logs

As you already know, you can create hundreds or thousands of coroutines, and those can be executed in one or more threads during their life cycle. Some of those coroutines will last for a long time, while others will be short-lived, maybe because they are tied to a temporary task. So, during debugging, it becomes a necessity to...
