Simplifying Android Development with Coroutines and Flows

By: Jomar Tigcal

Overview of this book

Coroutines and flows are the new recommended way for developers to carry out asynchronous programming in Android using simple, modern, and testable code. This book will teach you how coroutines and flows work and how to use them in building Android applications, along with helping you to develop modern Android applications with asynchronous programming using real data. The book begins by showing you how to create and handle Kotlin coroutines on Android. You’ll explore asynchronous programming in Kotlin, and understand how to test Kotlin coroutines. Next, you'll learn about Kotlin flows on Android, and have a closer look at using Kotlin flows by getting to grips with handling flow cancellations and exceptions and testing the flows. By the end of this book, you'll have the skills you need to build high-quality and maintainable Android applications using coroutines and flows.

What this book covers

Chapter 1, Introduction to Asynchronous Programming in Android, visits asynchronous programming in Android and shows the various ways it is being done now. Toward the end, the new recommended ways of coroutines and flows will be introduced.

Chapter 2, Understanding Kotlin Coroutines, introduces Kotlin coroutines and shows how they can be used for asynchronous programming in Android. It will demonstrate how to create coroutines, and discuss coroutine builders, scopes, dispatchers, contexts, and jobs.

Chapter 3, Handling Coroutine Cancelations and Exceptions, discusses coroutine cancelations, and how you can manage coroutine cancelations, timeouts, and exceptions properly.

Chapter 4, Testing Kotlin Coroutines, describes how you can test Kotlin coroutines in Android.

Chapter 5, Using Kotlin Flows, covers the basics of Kotlin flows and how they can be used for asynchronous programming in Android. It continues with creating flows with flow builders. It will also discuss flow operators, buffering and combining flows, and StateFlow and SharedFlow.

Chapter 6, Handling Flow Cancelations and Exceptions, explores how to manage cancelations, completion, and exceptions in your flows.

Chapter 7, Testing Kotlin Flows, provides details on how you can test the flows in your Android project.
