## What it is
A small Android library by Square that detects device shake gestures using the accelerometer sensor. It is a single-file library distributed via Maven/Gradle, now officially deprecated.

## Use cases
- detect when user shakes their android phone
- trigger an action on device shake gesture
- undo or reset feature activated by shaking
- shake-to-refresh in an android app
- listen to accelerometer shake events

## When to choose
- you need a tiny, dependency-free shake detection implementation for Android
- you are fine copying a single source file into your codebase
- you want a simple, proven accelerometer-based gesture listener

## When to avoid
- you need actively maintained or updated libraries
- you require gesture detection beyond shake (the project is deprecated)
- you are starting a new project and prefer supported alternatives

## Facets
- artifact type: library
- maturity: abandoned
- function: mobile-framework
- domain: mobile-development, android-tools
- platform: jvm
- tags: shake-detection, accelerometer, sensors, android-library, deprecated, android
