Wane saniyoyi na gida da ake amfani da su a cikin Android (MVVM, MVI, Clean Architecture)?

Question

Accepted Answer

Aikace-aikacen Android suna amfani da **saniyoyi na gida** da ke raba abubuwa da kuma inganta jiyya da gwaji — musamman **MVVM** (Model-View-ViewModel, shawarwarin Google), **MVI** (Model-View-Intent), da **Clean Architecture**. Fahimta su ita ce mahimmi don gina aikace-aikace masu kyau.

## MVVM — Model-View-ViewModel (an ba da shawarwari)

```text
MVVM separates the UI from logic and data:
  VIEW (Activity/Fragment/Compose) → displays UI, observes the ViewModel, forwards events
  VIEWMODEL → holds UI state + logic; exposes observable state (LiveData/StateFlow);
    survives config changes; NO Android framework/UI dependencies (testable)
  MODEL → data (repositories, data sources)
→ The View observes the ViewModel's state and updates reactively. Google's recommended
  pattern (using Architecture Components).
```

## MVI — Model-View-Intent (takowa ta gida)

```text
MVI adds a strict UNIDIRECTIONAL data flow with a single immutable STATE:
  Intent (user action) → reducer → new immutable STATE → View renders the state
  → one source of truth (the state); predictable, easy to debug/test; popular with Compose
  → more structure/boilerplate; good for complex state
```

## Clean Architecture (yadudduka)

```text
Layered architecture with dependencies pointing INWARD:
  PRESENTATION (UI + ViewModels) → DOMAIN (use cases, business logic, entities — pure,
    framework-independent) → DATA (repositories, data sources)
  → business logic is independent of frameworks/UI/data details → highly testable,
    maintainable, scalable (more layers/boilerplate; for larger apps)
```
