## What it is
A smooth version of Google's Support Design AppBarLayout for Android, fixing the fling/scroll stutter issue when used with RecyclerView. It is now deprecated since the fix was merged into support design 26.0.0+.

## Use cases
- fix appbarlayout fling stutter with recyclerview
- smooth scrolling toolbar collapse on android
- material design app bar with quick return behavior
- collapsing toolbar with enter-always scroll flags
- app bar that works with swiperefreshlayout
- viewpager with collapsing appbar layout

## When to choose
- maintaining a legacy Android app on support design libraries below 26.0.0
- you need smooth fling behavior with AppBarLayout on old support library versions

## When to avoid
- starting a new Android project - use the official support/AndroidX design library instead
- your support design library is version 26.0.0 or above, where the fling issue is fixed
- you need an actively maintained library

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, animation
- domain: android-tools, mobile-development, frontend
- platform: -
- tags: appbarlayout, material-design, android-support-library, deprecated, scrolling, java, android
