Backboard is a motion-driven animation framework for Android built on top of Facebook's Rebound spring physics library. It simplifies coupling springs to views and touch events via Performers, Imitators, and Actors.

Use cases

  • animate android views with spring physics
  • make views follow touch drags smoothly
  • create bounce and bloom UI animations
  • map motion events to view properties
  • build interactive gesture-driven interfaces on android

When to choose

  • building Android UIs with natural spring-based motion
  • you want a simpler API over Facebook Rebound
  • animating views in response to touch gestures

When to avoid

  • targeting non-Android platforms
  • you prefer Jetpack Compose animation APIs
  • the project needs actively maintained dependencies
