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 6: Assembling a Repository

In this chapter, we will begin by discussing the application's data layer and the components that make up this layer, including repositories and data sources. We will then move on to the topic of repositories, one of the application layer's components, and the role they play in managing the data of an application. In this chapter's exercise, we will continue the project started in the previous chapter by providing the repository implementations for the abstractions defined there and also introducing new abstractions for the different types of data sources.

In this chapter, we will cover the following topics:

  • Creating the data layer
  • Creating repositories

By the end of the chapter, you will have learned what the data layer is and how we can create repositories for an Android application.
