01_03. Comparison of Fundamental Dependency Injection Techniques

Description

Learn the fundamental theory of Dependency Injection and use Dagger 2 to develop clean Android applications

What you’ll learn

Understand the architectural significance of dependency injection in Android applications
Master Dagger 2 dependency injection framework
Integrate Dagger 2 into Android applications using the simplest and the cleanest approach
Implement Pure Dependency Injection without any third-party frameworks

Requirements

Hands-on experience with Android development (preferably 6 months or more)
Knowledge of Java


Description

Many professional Android developers use Dagger 2 dependency injection framework to build clean and maintainable Android applications. Dependency injection is one of the most fundamental and beneficial architectural pattern in object-oriented design, and it is used extensively in Android world.
After completing this course you’ll know what dependency injection is and how to use Dagger 2 dependency injection framework.
You’ll understand that dependency injection is not about frameworks, annotations, reflection or code generation, but about the fundamental design and architecture of your Android apps. You’ll realize that dependency injection is not black magic and that all real-world Android applications, even the simplest ones, can benefit from it.
Even though the end goal of this course is to teach you Dagger 2, I will also show you how to implement so-called Pure Dependency Injection in Android without using any third-party libraries at all. This will allow you to fully understand and appreciate the role of dependency injection frameworks.
