What methods can be used to structure an application by breaking it into separate components or modules?

To structure an Android application into separate components or modules, several approaches are used:

• Architectural patterns:

  • MVVM (Model-View-ViewModel) — separates UI (View), business logic (ViewModel), and data (Model).
  • MVP (Model-View-Presenter) — similar to MVVM but with a Presenter instead of ViewModel.
  • Clean Architecture — separation into layers: Presentation, Domain, Data.

• Gradle modules — dividing the project into independent modules (app, feature modules, core), which improves scalability and reusability.

• Using Android Jetpack Components — for example, Navigation Component for managing navigation between fragments.

• Dependency Injection (DI) — injecting dependencies via Dagger/Hilt for loose coupling of components.

• Fragments and Activities — dividing UI into independent parts.

Such structuring helps maintain code, facilitates testing, and supports app development.
