The first file is a Kaywa reader. It is a V3 version, but works fine in A1200. It is basically a QR Code Reader. After install change permissions of multimedia recording to "Ask once per application, or else you'll get a nagging permission screen everytime you click on capture. Better still, change the permission as given in the sticky.
The second file is a barcode reader, which i made compatible with JAM. For Keymapping see the post...
[APP]: Java-adapter JAM 2.2 - utility for adding TouchScreen support to java apps
* =>Volume Up key
# =>Volume Down key
Just enter the barcode number, & press # to see the information. You dont have to take a picture or anything. Entering the number will give you all the details about the products.
Any problem with any of the apps, & update me here. I'll try to adress those

The kaywa reader hangs the fonafter using it for more than 5 times. So be advised. I'm working on it. Use it for 4 times. Close it, & reopen. If fon hangs, wait for sometime. If it is still hung. Remove the battery. Wait 10 seconds, insert the battery, switch on the fon. Don't worry, it wont damage your fon.
