## What it is
A deprecated Android library that implements an indexed contact list (with A-Z side index bar and sticky headers) using RecyclerView. It is distributed via JitPack and written in Java.

## Use cases
- build a contact list with an A-Z index bar in Android
- add sticky section headers to a RecyclerView
- implement a fast-scrolling indexed list like the phone contacts app
- create an alphabet side bar for list navigation in Android

## When to choose
- you need a quick indexed contact list in a legacy Android app using the support library
- you want a simple Java-based RecyclerView index bar example to learn from

## When to avoid
- you are starting a new project - the library is deprecated and unmaintained since 2017
- you use AndroidX instead of the old support library
- you need active support or bug fixes

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, developer-tools
- domain: mobile-development, android-tools
- platform: jvm
- tags: recyclerview, android-library, contact-list, index-bar, deprecated, jitpack, android, mobile
