Random OnDetected invoked when not actively scanning QR codes

[LeoJHarris]

Hi there! Thanks for what appears to be a great QR code scanner 👍 one issue I noticed however is I have a tabbed page with 2 child pages, one happens to be a page with a QR code scanner view in it to scan items and another page has scanned barcodes. I noticed randomly that on the scanned barcodes page the app/device randomly vibrated and scanned as though it was scanning a barcode but I didn't even have a barcode being scanned in front of the device. I put break point in on the OnDetected event method to see the result and looks like following:

It seems rather odd it would randomly trigger the QR code OnDetected event. Would there be a reason for this since I don't even have a QR code in front of the camera?

Hi @LeoJHarris

Thank you.
After investigation on the provided screenshot, the barcode scanner may detect a barcode you do not expect as the sensor is quite sensitive and it serves many kinds of barcodes, so I suggest you try to narrow down the supporting barcode types.
If your application is designed only for a certain barcode format such as QRCode you should call GoogleVisionBarCodeScanner.Methods.SetSupportBarcodeFormat.

//Default All
//Set detect QRCode only
GoogleVisionBarCodeScanner.Methods.SetSupportBarcodeFormat(BarcodeFormats.QRCode);
//Set detect QRCode + Code39
GoogleVisionBarCodeScanner.Methods.SetSupportBarcodeFormat(BarcodeFormats.QRCode | BarcodeFormats.Code39);
