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.

Chapter 7: Introducing Presentation Patterns in Android

In this chapter, we're continuing our journey of exploring ways to architect Android applications. More precisely, we will be making sure that our applications split responsibilities correctly with the introduction of presentation patterns.

In the first section, Introducing MVC, MVP, and MVVM as presentation patterns, we will provide a short overview on why we need presentation patterns, and we will explore how most common patterns are implemented in Android projects.

Next up, in the Refactoring our Restaurants App to fit a presentation pattern section, we will refactor our Restaurants App to fit the MVVM presentation pattern, while also understanding why MVVM is best suited for our Compose-based app.

In the last section, Improving state encapsulation in ViewModel, we will see why it's important for the user interface (UI) state to be properly encapsulated inside the ViewModel, and we will explore how to achieve...
