How can I open an existing barcode scanner from my app and get the scanned value.
I'm guessing the is an OEM android hardware device that has an inbuilt scanner? we looked at this route a while back (briefly).
can you explain better your problem?
The scanner is integrated in the Device? Or is connected via bluetooth?
The scanner is integrated in the Device
which device? Usually there are specific SDK for this.
The scanner is an installed application in the device
You already asked about how to reach into another app and pull out the value. You don't.
You're going to have to write your app to talk to the scanner device, do the scan, and get the value. You can't just piggy back on someone else's app.
What device is it?
