News

In this project, I built an android app to discover popular and recent News Headlines. I built clean UI, sync to a server, and present detailed information of each News Headline, allowing users to 'favorite' News Article.

NOTE:

To run this app, you must also have an API Key defined as a variable named API_KEY in the file ArticleMediator.kt located at com.mayank_amr.news.data.repository.paging package.

Specifications:

• List of Top Headlines Country: India Default Tag: Technology, where 'Tags' represent 'Category' in the API. All categories in API docs are present in horizontally scroll.
• Sorted news by latest on top.
• Clicking on different tags should result in headlines from appropriate categories.
• Clicking Card Opens Detail Screen.

Used:

• Used Pagination - lazy load at the end of every 10 cards.
• Used Room DB for saving favourites => Favourites should also be categorized by tags.
• Used Room DB for caching logic - Once cached, should work offline without network.
• Cached workflow works as same as online workflow .i.e., tag categorization with the cached data.
• Used Retrofit and Kotlin Flow for networking [and] to observe changes in Room and update the UI.

Edge workflow:

• Open app when offline => load cached data => scroll to bottom => turn on network => auto paginates.
• Maintained proper scroll position when Room data is updated with new data from API.
• Creative recycler view interactions / animations and pull-to-refresh.
