2. Why clean architecture? • All powerful Activities and Fragments • Separate business logic from Android framework • Improved testability
3. MVC Model View Controller
5. MVC Supervising Controller • The View relays user input to the Controller • The Controller processes input and updates the Model • Changes in Model state are used to update the View
6. MVP Model View Presenter
8. MVP Passive View • View forwards user inputs and lifecycle events to the Presenter • Presenter interacts with Model to format data for display
9. MVVM Model View ViewModel
11. MVVM Presentation Model • ViewModel contains data field for every component in the View • Data binding and synchronization
12. MVPC Model View Presenter Controller
14. MVPC WTF • Modified version of MVP to accommodate Android framework • Cleanly separates business logic from UI and Activity lifecycle • Enables unit testing of non-Android components ◦ Presenter ◦ Model
