In this series of articles, I’d like to introduce the most common design patterns with examples of Android implementations in practice.

Join Jon Bott for an in-depth discussion in this video, How to use the exercise files, part of Android App Development: Design Patterns for Mobile Architecture. It contains all kinds of resources about Android UI patterns, such as UI Pattern Evolution — FAB-in-Bottom-Nav, Toolbar Delight and the like. 2. Apple-style MVC motivates developers to put all logic into a UIViewController subclass. You can see that the modules are created and linked together on startup. The more famous being  Model-View-ViewModel (MVVM) and Model-View-Presenter (MVP). Having developed a project with MVP + Interactor and by helping a coworker to develop a full VIPER Android project, I can safely say that the architecture does work on Android and it’s worth it.
