Base Features

• App fetches news content from CBC Api and shows in the app with Android View.
• Filterers the news feed by the dynamic "type" field from the Api.
• When App loses network connection it notifies the UI.
• 2-3 Unit and/or UI Tests.
• A Readme file to onboard a developer.

Bonus Features

• Data persistence.
• Pagination.

TO-DO

• Fix the label bug when saving each News Item.
• Fix ui when we save each item (when saving data it goes straight to offline mode ~ This can be fixed by creating two fragments and observe each data source in each fragments).
• More Unit tests with Mockk or Mockito

Insights

• Based on the scope of project and requirement decided to go with Model- View - Model Architecture.
• Decided not implement dependency injection for the simplicity and maintainability and reduction of overhead in terms of setup and initialization
• Chose recycler view over list view based on it's performance, flexibility, Customizability, Separation of concerns and Integration with DiffUtil
• Used horizontal- recycler view for filtering because of the dynamic nature of "type" data coming from api
• Used Floating action button to load all news again after filtering.
