Simplifying Android Development with Coroutines and Flows

Part 1 – Kotlin Coroutines on Android

In this part, we will introduce the concept of asynchronous programming and discuss the new and recommended way to do it with Coroutines. We’ll learn how to create coroutines, handle cancelations and exceptions, and test them.

This section comprises the following chapters:

  • Chapter 1, Introduction to Asynchronous Programming in Android
  • Chapter 2, Understanding Kotlin Coroutines
  • Chapter 3, Handling Coroutine Cancelations and Exceptions
  • Chapter 4, Testing Kotlin Coroutines

Key benefits

  • Find out how to improve app performance with Kotlin coroutines
  • Discover the new recommended ways to use Kotlin coroutines and flows
  • Learn the basics of asynchronous programming, along with an overview of coroutines and flow

Description

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.

Who is this book for?

This book is for intermediate-level Android developers who want to level up their Android app-building skills. Familiarity with Android development and basic knowledge of Kotlin are needed to make the most of this book.

What you will learn

  • Understand how coroutines and flows differ from existing ways
  • Apply asynchronous programming in Android with coroutines and flows
  • Find out how to build your own coroutines and flows in Android
  • Handle, manipulate, and combine data in coroutines and flows
  • Handle cancellations and exceptions from coroutines and flows
  • Discover how to add tests for your coroutines and flows
  • Integrate coroutines and flows into your Android projects

Need help with Android coroutines to shorten demands on the main thread and reduce error? “Simplifying Android Development with Coroutines and Flows” Packt, by Jomar Tigcal is a simple work to introduce or refresh skills in this area. Android’s predominance on mobile devices means managing the amount of computing resources is always of critical importance. This work first covers the importance of coroutines for asynchronous work and then demonstrates flows when one needs the code to emit multiple values at the same time. A useful reference if spending any amount of time on Android programming. The book only has two sections, one on coroutines and one on flows. The sections mirror each other by describing first how to build the code, then catching cancellations and exceptions, and finally, testing the code for success. The building code sections are well-documented with clear examples. All examples are built around a sample code for calling movie titles from an existing database. Once capable of writing the code, the next step is finding ways to make sure the code continues running successfully. Included are ways to find the exceptions, stop at a pre-defined time, or filter for various values. The advantage here of flows over coroutines is that flows can manage multiple data inputs and filter over a wider range, such as being able to select only the most popular movies rather than the one-to-n listing. The final component, of course, for any code is being able to test. The author includes several test samples to either manually build into the code or use JUnit4 to automate across multiple code samples. Understanding how to test is a key element of knowing how code works, and how to build better code to accomplish goals. Overall, an excellent short reference to one component of Android code. Useful to those coding Android now, or looking to in the near future. The one lack is detailed case studies offering examples of where to go when one moves past the basics. However, the code language and samples are more than sufficient to drive that train on your own.

This book will have you up and running harnessing the benefits of using Coroutines and Flows in your apps straight away. It packs a lot in with a brief introduction to asynchronous programming before covering both in-depth. This includes handling exceptions, cancellations and testing. The chapters finish with exercises to make it stick. I particularly liked the Flows section which excels in teaching how to use them in a clear way. Overall, highly recommended.
