TO DO

• Unify styles
• Implement pagination with Paging
• Implement custom base adapter to avoid boilerplate code (similar to Epoxy or PlaceHolderView)
• Implement data biding in RecyclerViews and ViewHolders
• Nested recyclerviews: Save and restore horizontal scroll position
• Clean up "Loading view" with Shimmer effect implementation
• Support Dark theme
• Localization
• Implement a cache invalidation policy
• Analyze a better data update policy:
  • Add a work to update local data periodically in background
  • Update data from remote if it was not updated in a certain time. In other case get data from local storage.
• Add Github Actions:
  • Check PRs (Danger validation + run tests)
  • Build APK and publish on Firebase based on branching process to be defined.
• Add more unit tests (code coverage > 90%)
• Integration tests (with OkReplay)
• UI tests
• End to end tests

Future improvements

• Migrate XML layouts to Jetpack Compose
• Analyze separate code: one module by feature
