## What it is
An Android library that wraps a modified ZXING Barcode Scanner to provide a drop-in camera view for QR code detection. It notifies listeners when a QR code is decoded and exposes control point coordinates, making it usable for augmented reality overlays.

## Use cases
- scan qr codes with the android camera in my app
- decode qr codes from a live camera preview on android
- get qr code corner point coordinates for augmented reality
- embed a qr code reader view in an android layout
- build a qr scanner activity with torch and autofocus control

## When to choose
- you need a simple embeddable Android QR scanning view with decoded point coordinates
- you want AR-style overlays anchored to QR code control points
- you prefer a lightweight view-based integration over a full scanner app

## When to avoid
- you need an actively maintained library with recent bug fixes and security updates
- you need to scan barcode formats beyond QR codes
- you target modern Android camera APIs like CameraX and want current best practices

## Facets
- artifact type: library
- maturity: abandoned
- function: computer-vision, image-processing, ui-components
- domain: mobile-development, computer-vision
- platform: -
- tags: qr-code, zxing, camera-preview, barcode-scanning, augmented-reality, android
