## What it is
A small Android Java library that simplifies creating Activity transition animations, including shared-element style reveals between views. It is API compatible with Android 2.2+ and offers customizable expose and show methods.

## Use cases
- animate transitions between android activities
- create shared element transition from a view to a detail activity
- add circular reveal animation when opening an activity
- transition an image from a list item to a fullscreen detail screen
- customize activity open animations with color or inflate effects

## When to choose
- you need Activity transition animations on old Android versions below the native transition API
- you want a simple, lightweight helper with customizable reveal effects

## When to avoid
- you target only modern Android and can use the built-in Activity transition APIs
- you need Kotlin-first or actively maintained libraries with recent releases
