The RSS reader. UI is flawed and could use lots of work. Technical part seems to work fine.
Feeds can be added on main screen, deleted from feed screen. All article data is deleted with feed by using foreign key power. 
I have no idea why I needed ContentProvider. Probably I didn't, but the task said I did.
Additionally, I managed to pull off data refreshing in UI without use of broadcast. What an achievement.
Additionally, the app might misbehave if it gets non-rss URL. Don't feed it invalid URLs.
