Android Dependency Injection with Hilt and Kotlin

Modern Android development requires clean, modular, and maintainable code, which is difficult to achieve without proper dependency management. Implementing dependency injection manually often leads to verbose boilerplate code and architecture that is hard to scale. This text-based course guides you through the core concepts of dependency injection using Hilt, the standard framework for Kotlin-based Android applications. You will transition from writing tightly coupled code to designing modular, testable, and robust apps with clean architecture. By understanding how dependencies are scoped and provided, you will be able to manage complex application lifecycles with ease. What you'll learn: - Understand the core principles of dependency injection and why it is essential for modern Android architecture. - Configure Hilt in Kotlin projects to manage the lifecycle of your application's dependencies automatically. - Implement constructor, field, and method injection to decouple your classes and improve code reusability. - Define custom Hilt modules, qualifiers, and entry points to handle complex dependency scenarios and external libraries. - Integrate Hilt with modern Jetpack components, including ViewModels and state management workflows. - Practice writing robust unit tests by swapping real dependencies with test doubles using Hilt's testing APIs. You will start by exploring the foundational concepts of dependency injection, learning how to set up Hilt from scratch. From there, you will progress to scoping, architectural integration, and testing strategies through clear written explanations and practical code examples. This course is designed for Android developers who are familiar with Kotlin basics and want to adopt modern architecture patterns. No prior experience with dependency injection is required.
