## What it is
CZXing is a C++ port of ZXing for Android that provides WeChat-level QR code and barcode scanning, including WeChat's detection and super-resolution decoding models. It ships a ready-made scan activity plus lower-level components (DecodeEngine, CameraView, ScanLayout) for customization.

## Use cases
- scan QR codes in an Android app like WeChat does
- generate QR codes on Android
- scan barcodes such as EAN-13
- decode small or blurry QR codes with super-resolution
- build a custom camera-based scanner UI
- continuously scan codes without closing the screen

## When to choose
- you need high-accuracy QR/barcode scanning on Android comparable to WeChat
- you want a prebuilt scanner activity with customizable UI
- you need low-level access to the decoding engine or camera view

## When to avoid
- you target platforms other than Android
- you need a maintained, permissively-licensed library (no license file is present)
- you want a pure-Java/Kotlin solution without native .so libraries
