This is a simple RSS feed reader app that currently reads my blog (Android Kotlin Weekly)'s feed - rss.xml. It is written in Kotlin and Jetpack Compose.
This app is work in progress and may be over-engineered to showcase the best practices (use cases for example) and diverse array of technologies.
- Fetch articles from RSS feed
- Bookmark articles
- Share articles
- Mark articles as read / unread
- Search articles
- New article arrived notification
- Deep link support for all article URLs
- Google Play in-app rating & review
- Add login authentication
- Android Studio Koala or later

| StateFlow | Expose StateFlow in ViewModel |
| Accompanist System UI Controller | Set system bars color |
| Accompanist Permissions | Request post notification runtime permission |
| PullRefresh | Show article referesh indicator (was migrated from Accompanist SwipeRefresh) |
