Jetpack Compose UI - proof of concept

1. Jetpack Compose UI
”a modern declarative UI Tookit to simplfy and
accelerate native Android Ui development with less
code, powerfull tools and intuitive Kotlin APIs”

3. Key points
• Built entirely with Kotlin (Compose Compiler – Kotlin Compiler plugin)
• Not views – Modules to create UI
• Unbundled from OS – same code for Mobile and Desktop apps
• It’s easy to create custom views – uses Canvas under the hood.
• Compatible with existing Android apps, so you can adopt it
progressively
• Open source – can see progress and contribute
• Currently in Alpha stage. Don’t use in production!!!

4. Ui as a function

6. State
Internal State As a paramter

7. Not more reference to views

8. Not more reference to views

9. Not more reference to views
