Clean Android Architecture

By: Alexandru Dumbravan

Overview of this book

As an application’s code base increases, it becomes harder for developers to maintain existing features and introduce new ones. In this clean architecture book, you'll learn to identify when and how this problem emerges and how to structure your code to overcome it. The book starts by explaining clean architecture principles and Android architecture components and then explores the tools, frameworks, and libraries involved. You’ll learn how to structure your application in the data and domain layers, the technologies that go in each layer, and the role that each layer plays in keeping your application clean. You’ll understand how to arrange the code into these two layers and the components involved in assembling them. Finally, you'll cover the presentation layer and the patterns that can be applied to have a decoupled and testable code base. By the end of this architecture book, you'll be able to build an application following clean architecture principles and have the knowledge you need to maintain and test the application easily.

Summary

In this chapter, we explored the presentation layer of an Android application and a few different approaches for implementing this layer, such as MVC, MVP, and MVVM. We decided to focus on the MVVM approach because of the many benefits involving the life cycle and the compatibility with Jetpack Compose. We then looked at what happens when we want to split the presentation layer across multiple modules and how we can solve the common logic between these modules. In the chapter that follows, we will further build upon the MVVM pattern and study the Model-View-Intent (MVI) pattern, which further takes advantage of the Observable pattern to incorporate the user actions into states that can be observed.
