Mobile devices and barcodes

I was intrigued by this topic, so did a little research myself. First of
all, I'm not particularly inclined to jump through Apple's hoops when it
comes to installing applications on a phone I own. So, I only looked into
doing this for Android.
I came across this 6 line piece of code for reading barcodes on Android:
This requires that the Android device has the Android Scripting Environment
Here's information on installing the ASE within the Android emulator:
It's even possible to run scripts within ASE by snapshotting them as QR
barcodes (the script is encoded in the QR barcode):
How to access this from within Livecode (given that shell() is inoperable
on Android/iPhone)? It _might_ work by using the "launch URL" command,
giving a shell script that is recognised by ASE.
Of course, this solution is not going to be of use to those wanting to
distribute a barcode scanner Livecode app to the general public. However,
in a specific client environment it may be possible to concoct a solution.
Concocting this solution (indeed, investigating that it is possible) is
probably less complicated than writing an image-processor/barcode reader
oneself. Furthermore, if it is possible, it would open up a world of
possibilities on Android.
Here's a list of tutorials on other things that can be done within the ASE
(It's pretty impressive):
Hope that is of some use/interest to someone.
