This is a sample of Room.

The project has 5 modules.

• MainActivity
  • CheeseListFragment: shows the list of cheeses
    • CheeseListViewModel
  • CheeseDetailFragment: shows the detail of a selected cheese. User can mark it favorite.
    • CheeseDetailViewModel

See Guide to App Architecture for the overall design of this layer.
