## What it is
An Android library providing widgets that implement paper-folding animations, such as unfoldable detail views and foldable lists. It is distributed via Maven Central and includes a sample app demonstrating usage.

## Use cases
- add paper fold animation to android views
- create unfoldable detail view from a list item
- build foldable list animations in android app
- implement flip/fold transition between layouts
- add 3d folding effect to android ui

## When to choose
- you need a ready-made folding animation widget on Android with min SDK 14+
- you want a small (~31KB) dependency for fold/unfold transitions

## When to avoid
- you need actively maintained or updated library (last release 2018)
- your project targets AndroidX/modern tooling without adaptation
- you need animations beyond folding effects

## Facets
- artifact type: library
- maturity: abandoned
- function: animation, ui-components
- domain: mobile-development, android-tools
- platform: jvm
- tags: foldable-layout, paper-fold-animation, android-widgets, ui-animation, android
