Can you name the main levels in the concept of clean architecture?

The main levels in the concept of Clean Architecture typically include:

1. Entities — business logic and rules, independent of external details.
2. Use Cases — applications implementing specific business processes using entities.
3. Interface Adapters — transform data between layers, such as presenters, controllers, repositories.
4. Frameworks and Drivers — external components like UI, databases, web frameworks.

In Android development, this is often implemented through layer separation: Domain (entities and business logic), Data (data handling), Presentation (UI and user interaction). This approach ensures the independence of business logic from implementation details and simplifies testing and maintenance of the code.
