## What it is
An Android library that lets developers describe view animations declaratively using expectations (position, size, color, visibility) and run them as animations. It provides a fluent Java DSL for animating Android views toward a described end state.

## Use cases
- animate android views to a described layout state
- declarative ui animations on android
- animate views on scroll in android
- create material design transition animations
- describe expected view positions and animate to them

## When to choose
- building Android UIs in Java with complex view animations
- you want a readable declarative DSL instead of manual property animators
- animating multiple views together toward a target layout

## When to avoid
- developing in Kotlin with modern animation APIs like MotionLayout or Compose animations
- the project needs active maintenance - last release was 2020
- non-Android projects

## Facets
- artifact type: library
- maturity: maintenance
- function: animation
- domain: mobile-development, android-tools
- platform: -
- tags: android-ui, declarative-animations, java, material-design, android
