Overview of this book

With Jetpack libraries, you can build and design high-quality, robust Android apps that have an improved architecture and work consistently across different versions and devices. This book will help you understand how Jetpack allows developers to follow best practices and architectural patterns when building Android apps while also eliminating boilerplate code. Developers working with Android and Kotlin will be able to put their knowledge to work with this condensed practical guide to building apps with the most popular Jetpack libraries, including Jetpack Compose, ViewModel, Hilt, Room, Paging, Lifecycle, and Navigation. You'll get to grips with relevant libraries and architectural patterns, including popular libraries in the Android ecosystem such as Retrofit, Coroutines, and Flow while building modern applications with real-world data. By the end of this Android app development book, you'll have learned how to leverage Jetpack libraries and your knowledge of architectural concepts for building, designing, and testing robust Android applications for various use cases.

Introducing Kotlin coroutines

Coroutines are part of the Kotlin API. They introduce a new and easier way of handling async work and concurrency jobs.

Often, with Android, we need to run or execute different tasks behind the scenes. In the meantime, we don't want to block the main thread of the application and get an unresponsive UI.

To mitigate this issue, coroutines allow you to execute async work much easier while providing main-thread safety for your Android apps. You can use the Coroutines API by launching one coroutine, or more, depending on your needs.

In this section, we will cover three essential questions about the Coroutines API that derive from what we stated earlier:

  • What is a coroutine?
  • What are the features and advantages of coroutines?
  • How do coroutines work?

Let's jump in!

What is a coroutine?

A coroutine is a concurrency design pattern for async work. A coroutine represents an instance of suspendable computation.
