## What it is
An Android sample application in Java demonstrating how to use CoordinatorLayout.Behavior to replicate the Hangouts 4.0 profile animation. It serves as an educational example of custom CoordinatorLayout behaviors.

## Use cases
- learn how to write a custom CoordinatorLayout.Behavior in Android
- replicate the Hangouts profile header animation
- understand scroll-dependent animations in Android layouts
- find example code for collapsing toolbar effects
- study material design motion patterns on Android

## When to choose
- you are learning Android UI development and want a concrete CoordinatorLayout.Behavior example
- you need a reference implementation of a profile-style collapsing animation

## When to avoid
- you need a maintained production library - this is an old demo with no license and no recent activity
- your project uses Kotlin or Jetpack Compose rather than Java views
- you need comprehensive documentation or support

## Facets
- artifact type: application
- maturity: abandoned
- function: animation, ui-components
- domain: mobile-development, android-tools, tutorials
- platform: -
- tags: android, sample-app, coordinatorlayout, material-design, java, demo, mobile
