Summary

In this chapter, we looked at the DI pattern and some of the more popular libraries that are available to apply this pattern to an Android application. We looked initially at Dagger 2 and how it can be integrated into an application, and then we analyzed the Hilt library, which is built on top of Dagger 2 and solves further problems that are specific to Android development.

There are other libraries that can be used to manage dependencies, such as Koin, which uses the Service Locator pattern (in which a registry is created and dependencies can be obtained) and is developed for Kotlin development. The exercise in this chapter showed how Hilt can be integrated with other libraries into an Android application. The problem is that the application still has no shape; there isn't anything we can point to that indicates what the use cases are. In the chapters that follow, we will look further into how we can structure our code to give it a shape using the Clean Architecture...
