Have been using the zxing barcode reader up until recently, but have had some issues making use of the front camera. Therefore, we decided to switch to using the Google Vision API.
It is working but the scanning is less than good. It is not able to find barcodes on all devices. In addition, the preview has some ratio issues and is seemingly unable to focus.
Also have not found a xamarin implementation of how-to make a boxes showing/tracking the located barcodes ( https://developers.google.com/vision/android/multi-tracker-tutorial ).
The code we use is equal to this code: https://github.com/eddydn/XamarinQrCodeCamera
Any suggestions for how-to enhance the reader and implement tracking of the barcodes?
