Hello,
As I said in the subject I am trying to select an element of a gallery with the value of barcodescanner.
I wanted it to work like this:
1. The barcode reader is scanning something.
2. If a barcode is scanned with a useable value, it is selecting an element of a gallery (compares the value of the barcode scanner with a value of the element )
3. Navigating to the DetailScreen
This is what I put in the OnScan of the barcode reader (which does not work):
