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.

Chapter 4: Managing Dependencies in Android Applications

In this chapter, we will analyze the concept of dependency injection (DI) and the benefits it provides and look at how this was done in the past in Android applications either through manual injection or using Dagger 2. We will go over some of the libraries used in Android applications, stopping and looking in more detail at the Hilt library and how it simplifies DI for an Android application.

In this chapter, we will cover the following topics:

  • Introduction to DI
  • Using Dagger 2 to manage dependencies
  • Using Hilt to manage dependencies

By the end of this chapter, you will be familiar with the DI pattern and libraries such as Dagger and Hilt, which can be used to manage dependencies in Android applications.
