## What it is
A deprecated Android custom view library that implements the Material Design bottom navigation pattern as a customizable component. It allows defining tabs via XML resources with shifting and fixed styles, but the author recommends using Google's official BottomNavigationView instead.

## Use cases
- add a material design bottom navigation bar to an android app
- create a tabbed bottom bar with icons and labels in android
- implement shifting bottom navigation for tablets
- customize bottom navigation behavior in xml
- build an android app with bottom tab navigation

## When to choose
- maintaining a legacy Android project that already depends on it
- needing bottom navigation features missing from the official BottomNavigationView on very old Android support libraries

## When to avoid
- starting a new Android project - use the official BottomNavigationView
- needing a maintained library with active support and bug fixes
- targeting modern Android versions with Jetpack libraries
