Redesign of the contact screen and contact detail screen for Smart Contact Reminder app inspired by design by Yaroslav Zubko.
The original app is available from Google Play and project website.
The network API is simulated by the FakeApi class with returns static data with a random delay.
The repositories (ContactCategoryRepository and ContactPersonRepository) communicate directly with the API, obtain the data requested as DTOs and map them to Entities used within the domain layer.
In our very simple sample app, there's almost no business logic. The mappers map DTOs to Entities 1:1. However, a more complex application would require more advanced mapping of DTOs. It would also use UseCases for encapsulating and reusing of business logic.
The sample app uses Activites and Fragments as basic UI screen elements. JetPack ViewModels are used for keeping state between configuration changes and directly communicate with Repositories. View state is represented by LiveData which is observed by the View component.
