## What it is
ActionBarSherlock is a deprecated Android library that provides a unified action bar API across Android versions, using the native action bar on 4.0+ and a custom backport implementation on older versions. It lets developers style and interact with the action bar through a single API and theme.

## Use cases
- add an action bar to Android apps supporting 2.x devices
- use one action bar API across all Android versions
- style the action bar to match app theme on old Android versions
- backport Ice Cream Sandwich action bar to pre-4.0 devices

## When to choose
- maintaining a legacy Android app already built on ActionBarSherlock
- targeting Android 2.x-3.x devices with a consistent action bar

## When to avoid
- starting any new Android project (use AppCompat instead)
- targeting only Android 4.0+ where the native action bar exists
- needing ongoing support or new features

## Facets
- artifact type: library

- function: ui-components, mobile-framework
- domain: mobile-development, android-tools, cross-platform
