Have you had experience working with the concept of Clean Architecture in your projects?

Yes, I have experience working with the concept of Clean Architecture in Android projects. Clean Architecture helps structure the application so that business logic is separated from implementation details, making it easier to maintain, test, and scale.

Main layers of Clean Architecture:

• Entities — business logic and rules.
• Use Cases — specific usage scenarios implementing business logic.
• Interface Adapters — data transformation between layers, such as ViewModel, Presenter.
• Frameworks & Drivers — implementation details like database, UI, network.

In Android, this is usually implemented by dividing into modules or packages, where the UI layer (Activity, Fragment) interacts with ViewModel, which in turn interacts with Use Cases, and those with repositories and entities.

An example of a simplified structure:

- domain/
  - entities/
  - usecases/
- data/
  - repositories/
  - datasources/
- presentation/
  - viewmodels/
  - views/

This approach increases testability and reduces component coupling.
