Jetpack Compose is changing how UI is being built on Android. This new toolkit is replacing the now 10-year-old, somewhat tedious View system with a declarative, functional approach, and promises to simplify and speed up UI development.

This is happening at the same time as Flutter continuously gaining popularity, and iOS getting its own declarative UI APIs with SwiftUI.

This session explains what Jetpack Compose is, and then shows a quick example of interesting UI with it, based on this blog post https://medium.com/google-developer-experts/compose-oclock-50c778a6360
