Qr scanner android github
quickie is a Quick Response (QR) Code scanning library for Android that is based on CameraX and ML Kit on-device barcode detection. It’s an alternative to ZXing based libraries and written in Kotlin. quickie features:
- Easy API for launching the QR scanner and receiving results by using the new Activity Result API
- Modern design, edge-to-edge scanning view with multilingual user hint
- Android Jetpack CameraX for communicating with the camera and showing the preview
- ML Kit Vision API for best, fully on-device barcode recognition and decoding
There are two different flavors available on mavenCentral() :
| Bundled | Unbundled |
|---|---|
| ML Kit model is bundled inside app (independent of Google Services) | ML Kit model will be automatically downloaded via Play Services (once after app install) |
| 2.2 MB app size increase per ABI (you should use App Bundle or ABI splitting) | 550 KB app size increase |
| V3 model is used (faster, more accurate) | currently V1 model will be downloaded |
To use the QR scanner simply register the ScanQRCode() ActivityResultContract together with a callback during init or onCreate() lifecycle of your Activity/Fragment and use the returned ActivityResultLauncher to launch the QR scanner Activity.
⚠️ You can’t register the ActivityResultContract inside the OnClickListener lambda. This will fail since the code gets executed after the onCreate lifecycle!
Check out the sample inside this repo or visit the official Activity Result API documentation for more information.
The callback you add to the registerForActivityResult will receive a subclass of the sealed QRResult class:
- QRSuccess when ML Kit successfully detected a QR code
- wraps a QRContent object
- QRUserCanceled when the Activity got canceled by the user
- QRMissingPermission when the user didn’t accept the camera permission
- QRError when CameraX or ML Kit threw an exception
- wraps the exception
The content type of the QR code detected by ML Kit is wrapped inside a subclass of the sealed QRContent class which always provides a rawValue .
Currently, supported subtypes are: Plain , Wifi , Url , Sms , GeoPoint , Email , Phone , ContactInfo , CalendarEvent
See the ML Kit Barcode documentation for further details.
Use the ScanCustomCode() ActivityResultContract to create a configurable barcode scan. When launching the ActivityResultLauncher pass in a ScannerConfig object:
💡 You can optionally pass in an ActivityOptionsCompat object when launching the ActivityResultLauncher to control the scanner launch animation.

Project in Maintenance Mode Only
The project is in maintenance mode, meaning, changes are driven by contributed patches. Only bug fixes and minor enhancements will be considered. The Barcode Scanner app can no longer be published, so it’s unlikely any changes will be accepted for it. There is otherwise no active development or roadmap for this project. It is «DIY».

Privacy Friendly QR Scanner
The Privacy Friendly QR Scanner belongs to the group of Privacy Friendly Apps. The app supports its users in detecting malicious links: QR Codes provide new possibilities for an attacker, as QR Codes can contain malicious links, i.e. links to phishing webpages or webpages from which malware would automatically be downloaded. Therefore it is important to carefully check the link before accessing the corresponding webpage.
This app is optimized regarding the user’s privacy. It only uses the device’s camera in order to decode QR codes and barcodes.
Privacy Friendly QR Scanner belongs to the group of Privacy Friendly Apps and has been developed to provide a privacy friendly QR-Code/Barcode decoding application. More information can be found on https://secuso.org/pfa
Further development requires Android Studio, we recommend to use the latest version.
Mininum SDK: 17 Target SDK: 28
This app uses the help of the ZXing Projekt.
