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.

But before we do that, let's add more functionality inside the application to better highlight how mingling responsibilities can lead to unmaintainable code.

To summarize, in this section, we're going to be doing the following:

  • Adding more functionality inside our Restaurants app
  • Refactoring our Restaurants app to MVVM

Let's begin!

Adding more functionality inside our Restaurants app

When the Restaurants application is launched, the RestaurantsScreen() composable is rendered. Inside this screen, we are loading a bunch of restaurants from the server, and then we're displaying them to the user.
