...Its structure separates responsibilities into UI, ViewModel, repository, local data, and network data layers. Activities and fragments form the UI layer while ViewModels retain interface-related data and communicate with repositories. The repository determines whether requested information should come from local storage or a remote service. Local persistence is implemented with LitePal, while Retrofit retrieves information from web services. Dependencies flow in one direction between adjacent layers, making the project a practical example for learning structured Jetpack and MVVM development.
