BGAQRCode-Android is a QR code and barcode scanning and generation library for Android that provides both ZXing and ZBar implementations.
The library addresses the need for flexible QR code and barcode functionality in Android applications. It offers scanning capabilities through camera preview with customizable scan frames, support for full-screen or frame-region-only scanning, and the ability to recognize codes from gallery images. For generation, it wraps ZXing to create QR codes with custom colors and embedded logos, as well as one-dimensional barcodes. The tool includes features like flashlight control, front-facing camera support, pinch-to-zoom preview, ambient light monitoring to suggest flash usage, and automatic magnification for small codes. It provides both ZXing and ZBar backends, with ZBar including a fix for Chinese character encoding issues.
Developers should choose this library if they need a comprehensive barcode solution with UI customization options. The project suits applications requiring camera-based scanning with visual feedback and the ability to process images from the device gallery. The library was created by adapting an existing barcode scanner project to meet specific product requirements and offers more extensive customization than its source material.
The project maintains two separate demo applications showcasing ZXing and ZBar implementations respectively. Documentation includes layout file references and guidance on common integration issues such as proper lifecycle management to avoid black screen problems and correct view hierarchy setup to prevent preview compression on certain devices.
