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.

Suspending Functions and the Coroutine Context

So far, we have limited ourselves to writing suspending code using coroutine builders such as launch and async, but Kotlin offers more ways to write it. In this chapter, we will start by updating our RSS reader to actually display the articles that it retrieved, then we will learn about suspending functions and compare them with the async functions that we have been using so far. Also, we will cover the coroutine context and its use in detail.

Here is a summary of topics that will be covered in this chapter:

  • What a suspending function is
  • How to use suspending functions
  • When to use async functions instead of suspending functions
  • What the coroutine context is
  • Different types of contexts such as dispatcher, exception handlers, and non-cancellables
  • Combining and separating contexts to define the behavior of coroutines
