## What it is
An Android layout container library that animates the expansion and collapse of child views. It delegates sizing work to the parent layout so standard features like LinearLayout weights work correctly.

## Use cases
- animate expanding and collapsing views in an Android app
- build accordion-style UI sections
- make RecyclerView items expandable
- add horizontal expansion animations to layouts

## When to choose
- you need reliable expand/collapse animations with proper rotation handling
- you want LinearLayout weight and other parent layout features to work inside an expandable container

## When to avoid
- you need Jetpack Compose animations instead of XML layouts
- you need a heavily maintained library with frequent updates

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