Introduction10:01
Explore dependency injection in Android with Dagger and Kotlin, contrasting manual dependency injection and Dagger-based object creation, and implement a car with wheels and engine.

DAGGER Kotlin tutorial android part 2. FIELD INJECTION in any activity of androi6:21
Learn to use Dagger Kotlin to inject a car instance via field injection in an Android activity, by annotating fields, creating a car component, and injecting the main activity.
DAGGER Kotlin tutorial android part 3. @MODULE AND @PROVIDES. How to create impl10:00
Explore dagger 2 dependency injection with Kotlin by binding petrol and diesel engine implementations via @Module and @Provides, and assemble a car with a dagger component.
DAGGER Kotlin tutorial android part 4. Instances of third party classes using @M10:03
Learn to create implementor classes and modules for dagger, and provide third party instances by manual module wiring, using abstract functions and modules to supply wheels, engine, and related objects.
DAGGER Kotlin tutorial android part 5. METHOD INJECTION4:30
Explore method injection in Dagger 2 with Kotlin, where dependencies are provided to a method of a class such as remote, and Dagger creates the dependency instance automatically.
DAGGER Kotlin tutorial android part 6. FIELD INJECTION IN ANY CLASS5:40
Explore dagger kotlin android part 6: field injection in any class. Learn how dagger uses constructor annotations to create objects and enable automatic field injection in the main activity.
DRAGGER Kotlin tutorial android part 7. Inject runtime values to dependent objec6:56
Learn how to inject runtime values into dependent objects with Dagger 2 in Kotlin for Android, using modules and builders to pass a capacity value to a model.
DAGGER Kotlin tutorial android part 8. @COMPONENT.BUILDER AND @BINDINSTANCE10:07
Learn to pass runtime values to Dagger components in Kotlin for Android using a component builder and @BindsInstance, supplying power capacity to the car component.
DAGGER Kotlin tutorial android part 9. @NAMED5:15
Learn to use Dagger's named annotation to inject distinct power and engine capacity values in a car component. Wire the component with named dependencies to avoid constructor conflicts.
DAGGER Kotlin tutorial android part 10. @SINGLETON10:00
Learn how Dagger enforces a singleton by annotating Driver and components, ensuring one driver per app, and why an application-level component preserves this singleton through configuration changes.
DAGGER Kotlin tutorial android part 11. Component as application level6:05
Explore how to declare a car component at the application level using dagger in a Kotlin Android app to ensure a singleton driver and stable object lifecycles across activities.

Description

Dagger 2 is a leading dependency injection (DI) framework used in Android development, known for its efficiency and reliability. Our comprehensive course on Dagger 2 with Kotlin is designed for students aiming to enhance their Android development skills by mastering DI principles and techniques.

The course begins with an introduction to dependency injection, explaining its importance in modern software development. Students will understand how DI improves code modularity, testability, and overall maintainability. We will then delve into the specifics of Dagger 2, covering essential concepts such as components, modules, and scopes. Through clear explanations and practical examples, students will learn how these components work together to manage dependencies within an Android application.

Our course places a strong emphasis on hands-on learning. Students will engage in practical exercises and build real-world projects, applying Dagger 2 concepts in various scenarios. We will explore the integration of Dagger 2 with Kotlin, highlighting Kotlin-specific features that enhance the DI experience. This includes working with Kotlin’s concise syntax, leveraging extension functions, and utilizing advanced features like coroutines to manage asynchronous operations.

Throughout the course, students will learn to use annotations effectively, create custom scopes, and manage complex dependency graphs. They will also explore best practices for testing and debugging applications that use Dagger 2. By the end of the course, students will have a thorough understanding of Dagger 2 and will be able to implement it confidently in their Android projects.

This course is ideal for Android developers, from beginners to intermediate, who are looking to improve their code quality and streamline their development process. With Dagger 2 and Kotlin, students will be equipped to build robust, scalable, and maintainable Android applications, setting them apart in the competitive field of Android development.
