We are not sure. Is it because the Barcode Reader uses a mobile phone's Camera to take picture of the barcode and then read the barcode from the picture, rather than a more rare use case of using an actual hardware Barcode Scanner attached to the device?

 

Other than maybe the above, we're not sure of an answer on this one.

So you have a barcode integrated device such as a Zebra Android device and you want to use it with PowerApps?

Yes, and it is not able to read in PowerApps because the barcode reader uses the camera of a mobile phone to take a picture of the barcode and then read the barcode of the image, do you know if there is any solution?

Try this:

Add a text input control with the DelayOutput property set to true

In its OnChange property, add this:

Set(ScanValue,TextInput1.Text);
Notify("You scanned an item. Barcode Value: " & ScanValue);
Reset(TextInput1);
SetFocus(TextInput1);
//Add the rest of your code here..

Save and publish the app, try scanning something. It should pop up a notification with the barcode's value.

If that works, remove the Notify() function and add in the rest of your code after the SetFocus() function.

If this doesn't work, make sure that when you scan something, the scanner is sending an ENTER command after each scan. You can test this by opening a Notes app on your android device and scan something. It should enter the barcode value and then go to a new line.

This is something we're planning on doing at work, so keep me posted if it works! We've got a Zebra ordered and this is what I was going to try.

The problem is that it does not write what it scans in the text control, but if you do it outside of PowerApps, the reader works perfectly. That's why I explained before, it doesn't emulate keyboard.

I see. So even in a Notes app, it doesn't emulate a keyboard? Or is it specific to PowerApps?

Is it specific to PowerApps

I have a Zebra TC20 arriving today. I am going to experiment with it. I'll let you know what I find out.
