    how cold we scan barcode img that we already have in our device .
    is it posssible with app inventor 2

    • Edward M says:

      No, bar code scanning only works by viewing the bar code with the camera. It would be nice if we could re-scan a photo we’ve already taken but App Inventor’s bar code scanner feature does not support that.

    Says, “Two labels are used – one to display the text “Result:” and the other to display the returned code,” but only one label is shown.

  5. Steve says:

    Also, what’s needed to test via the emulator? I get “Error 1501: Your device does not have a scanning application installed.”

    • Edward M says:

      I would guess that the emulator does not simulate a camera or the scanner function for QR codes. Probably only works on an actual phone or tablet device.
