Do you have an understanding of fundamental architectural approaches?

Fundamental architectural approaches in Android application development include:

• MVC (Model-View-Controller) — dividing the application into data model, view, and controller that manages the interaction between them.
• MVP (Model-View-Presenter) — similar to MVC, but the Presenter takes on the interaction logic, making testing easier.
• MVVM (Model-View-ViewModel) — the ViewModel connects the model and the view, often used with Data Binding for automatic UI updates.

For example, MVVM allows separating UI logic from business logic, which simplifies maintenance and testing of the application.
