## What it is
AndroidTreeView is an Android library for rendering N-level expandable and collapsible tree views with customizable node views and styles. It supports node selection, dynamic add/remove of nodes, and saving tree state across configuration changes.

## Use cases
- display a file system hierarchy in an Android app
- build an expandable category tree with custom node layouts
- show a collapsible comment or outline tree
- implement multi-level selectable list navigation
- dynamically add and remove nodes in a tree UI
- persist tree expansion state across screen rotation

## When to avoid
- you are starting a new project - the library is deprecated and unmaintained
- you need Jetpack Compose or Kotlin-first solutions
- your tree is extremely deep on old Android versions, where view hierarchy crashes are a known limitation

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, state-management
- domain: mobile-development, android-tools, frontend
- platform: jvm
