L-applikazzjonijiet ta' Android jibbenfitaw minn patterns ta' arkitettura li jisseparaw il-concerns u jtejbu l-maintainability u t-testability — b'mod notevoli MVVM (Model-View-ViewModel, ir-rakkomandazzjoni ta' Google), MVI (Model-View-Intent), u Clean Architecture. Huwa importanti nfehmu dawn biex nibnu applikazzjonijiet strutturati tajjeb.
MVVM — Model-View-ViewModel (rakkomandatè)
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).
