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.

Summary

In this chapter, we learned how coroutines allow us to write async code in a much clearer and more concise way.

We understood what coroutines are, how they work, and why they are needed in the first place. We unveiled the core elements of coroutines: from suspend functions to CoroutineScope objects, to CoroutineContext objects and Dispatcher objects.

Then, we replaced the callbacks with coroutines in our Restaurants application and noticed how the code is much easier to understand and less nested. Additionally, we learned how to perform error handling with coroutines and integrated some of the best practices when working with coroutines.

In the next chapter, we will add another Compose-based screen to our Restaurants application and learn how to navigate between screens in Compose with yet another Jetpack library.
