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 9: Implementing Dependency Injection with Jetpack Hilt

In this chapter, we're continuing our journey of improving the architectural design of the Restaurants app. More precisely, we will be incorporating dependency injection (DI) in our project.

In the first section, What is DI?, we will start by defining DI and understanding its basic concepts, from what a dependency is, the types of dependencies, and what injection represents, through to concepts such as dependency containers and manual injection.

Afterward, in the Why is DI needed? section, we will focus in more detail on the benefits that DI brings to our projects.

In the last section, Implementing DI with Hilt, we will first understand how the Jetpack Hilt DI library works, and how to use it, and finally, with its help, we will incorporate DI in our Restaurants app.

To summarize, in this chapter we will be covering the following sections:

  • What is DI?
  • Why is DI needed?
  • Implementing DI with...
