I'm not sure how to word it better. It's quite simple though.
 
I have an EditText field in my Xamarin (C#) Android app. I need to scan a barcode (a QR code actually) and have the app know when the TC70 is finished scanning so it can parse the data from the scan.
 
If I were using a simple handheld scanner like an LS2208, that indicator would be the fact that it 'presses' the Enter button at the end of the scan. I just need some kind of event that I can use to tell when the scan is complete so I can take that text without the user having to make an additional action.
 
It's probably something simple, but my inability to explain it simply hampers my google-fu in this case. I apologize if it's answered somewhere easy to find.
