Dependency Injection

Dependency Injection (DI) is a design pattern used in Android development to enhance code modularity and ease of testing. It allows objects to be supplied with their dependencies instead of creating them directly within the objects. This leads to more maintainable and testable code.

Key Concepts of Dependency Injection

  1. Dependency: An object that another object depends on.

  2. Injection: The process of providing an object its dependencies.

Benefits of Dependency Injection

  • Decoupling: Reduces tight coupling between classes, making the system more modular.

  • Reusability: Promotes code reuse by allowing dependencies to be swapped easily.

  • Testability: Enhances the ability to test individual components by allowing mock implementations of dependencies.

  • Maintainability: Simplifies maintenance and future enhancements.
