## What it is
An Android support library providing backwards-compatible implementations of VectorDrawable and AnimatedVectorDrawable for API 14+ devices. It enables XML-defined icon morph animations (like hamburger-to-arrow) with transparent fallback to native Lollipop implementations on API 21+.

## Use cases
- use vector drawables on pre-lollipop android devices
- animate hamburger menu icon morphing to back arrow
- create play-pause button morph animations in xml
- render scalable icons without pixelation on older android versions
- add animated vector icons to an android app without writing java code

## When to choose
- you need VectorDrawable or AnimatedVectorDrawable support on Android API 14-20
- you want xml-only icon morph animations like play-pause or hamburger-arrow
- you maintain a legacy Android app with a low minSdkVersion

## When to avoid
- your minSdkVersion is 21 or higher since the platform provides these classes natively
- you use AndroidX, which includes built-in vector drawable support
- you need an actively maintained library, as the last release was in 2016

## Facets
