Kuidas saab organiseerida Android rakenduse arhitektuuri, et tagada selle tõhusus ja skaleeritavus?

To ensure the efficiency and scalability of an Android application, architectural patterns that divide responsibilities and facilitate code maintenance are commonly used. Main approaches:

• MVVM (Model-View-ViewModel) — separates UI (View), business logic (ViewModel), and data (Model). The ViewModel is independent of the View, making testing and scaling easier.
• MVP (Model-View-Presenter) — the Presenter manages logic and interacts with the View and Model.
• Clean Architecture — layered separation (Presentation, Domain, Data) with clear dependencies, increasing modularity and testability.

It is also important to use:

• Jetpack components (LiveData, ViewModel, Room) to simplify state and data management.
• Dependency Injection (e.g., Dagger or Hilt) to manage dependencies and facilitate testing.

Example of a simple ViewModel with LiveData:

class UserViewModel : ViewModel() {
    private val userRepository = UserRepository()
    val userData: LiveData<User> = userRepository.getUserData()
}

This approach allows separating UI from business logic and data, improving the application's scalability and maintainability.
