I'm doing a startActivityForResult() to launch a barcode scanner.
The problem is that if the user presses home from the scanner, then goes back to
my app and launches the scanner again, it appears to be launching a new
instance, and the camera is already busy, so it fails.
Is there a way to launch another app in this way, while insuring
that I will only launch one instance of the other app?
Thanks,
Tobiah
