  1. Why clean architecture? • All powerful Activities and Fragments •

    Separate business logic from Android framework • Improved testability
  2. 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
  3. MVP Passive View • View forwards user inputs and lifecycle

    events to the Presenter • Presenter interacts with Model to format data for display
  4. MVVM Presentation Model • ViewModel contains data field for every

    component in the View • Data binding and synchronization
  5. 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
  6. References Development of Further Patterns of Enterprise Application Architecture (DFPEAA)
