Dependency Injection in Android with Dagger 2 and Hilt. A complete guide to Dagger and Hilt dependency injection frameworks for Android development. Dependency injection is a design pattern that helps to decouple an object’s dependencies from its implementation. Injection allows an object to obtain the dependencies it needs without knowing the exact details of how those dependencies are implemented. This makes it easier to swap out implementations without affecting the overall functionality of a system.
Dependency Injection allows you to improve the flexibility and testability of your applications. The Hilt library provides a lightweight abstraction on top of Dagger 2 that makes it easy to write tests for your DI components.
Dependency Injection in Android with Dagger 2 and Hilt
In this complete course, you will learn how to use dependency injection in Android development. You will start by learning the basics of dependency injection and then move on to more advanced concepts. You will also learn how to create mock objects and test your code using Google Test. By the end of this course, you will understand dependency injection in Android development and be able to apply it to your own projects.
You will Learn
- Master Dagger and Hilt dependency injection frameworks
- Understand the relationship between Dagger, Dagger 2, and Hilt
- Learn the fundamental theory of Dependency Injection in Android
- Discover the best practices of Android development using Dependency Injection, Dagger, and Hilt
The dependency injection pattern can have a significant impact on the architecture of your Android applications. By specifying the dependencies that an object requires, you can ensure that all objects using that dependency are properly initialized and configured. This allows you to avoid common problems, such as errors in initialization or uncontrolled resource use.
With this course, you’ll learn what dependency injection is, understand how it affects the architecture of your Android applications, and master Dagger and Hilt dependency injection frameworks. This is a comprehensive resource, aimed to equip you with expert-level Android development knowledge and skills.
Even though the ultimate goal of this course is to make you comfortable with Dagger, you’ll also learn about so-called Pure Dependency Injection. That’s when you incorporate dependency injection into your Android applications without using any third-party libraries. Pure Dependency Injection is an important and useful technique and, in addition, mastering Pure DI will allow you to see what Dagger brings to the table and appreciate its features.
