XKCD Comic Reader (unofficial)

Fan made XKCD comic reader using the official JSON interface.

Architecture

• The app is entirely written in Kotlin.
• Dagger 2 Android is utilised for Dependency Injection.
• There is a single Activity which swaps Fragments inside a Non-Swipeable ViewPager (custom view) using a Bottom Navigation View.
• Remote Data: Network calls are handled by Retrofit 2.
• Local Data: There is a local Room Database for persisting fetched comics and recording user favourites. There is also an extra table created for handling Paging.
• Data loading and writing is abstracted behind a ComicsRepo.
• Business logic is handled by reusable Interactors who also handle threading via injected schedulers.
• Each Fragment has its own Android ViewModel that emits actions via LiveData.
• View Binding is in turn handled by each Fragment's dedicated View Binder.
• Swiping cards is handled by the latest version of Card Stack View which uses a recycler adapter.
• Favourites are toggled using a custom FavouriteImageView.
