Both iOS and Android allow apps interacting with each other. iOS has URL schemes, Android has Intents which are obviously far more elegant. There are tricks you can play to have apps intercept web page visits on Android [1], but other than that, web apps are disconnected from native apps.
That's ... one way to characterize Intent Filters. They enable, more or less, exactly what you talk about in the article, as I mentioned in my other comment.
