## What it is
An Android library that implements the Material Design ripple touch effect for views, compatible with Android API 9+. It provides a customizable RippleView wrapper with configurable color, duration, alpha, zoom, and completion listeners.

## Use cases
- add material design ripple effect to buttons on older Android versions
- customize ripple animation color and duration in Android layouts
- wrap any view with a touch ripple animation
- detect when ripple animation completes in Android app
- add zoom animation to clickable views

## When to choose
- supporting Android API 9+ where native ripple is unavailable
- needing fine-grained XML customization of ripple appearance
- wanting a lightweight drop-in view wrapper

## When to avoid
- targeting only Android Lollipop 5.0+ where native ripple exists
- starting a new project given the library is no longer actively developed
- needing Kotlin-first or Jetpack Compose solutions

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: mobile-development, android-tools
- platform: jvm
