Re: barcode example not working

I am able using Torch simulator to test barcode examples. I am able to scan QR-codes, but unable to scan EAN-13 barcode. The lines are visible clearly. And I used the example EAN-13 barcode image of Wikipedia for testing. What may be the problem? Please help me to find the problem.

 

 

Thanks,

Re: barcode example not working

Good morning,

I found the reason for my problem. The barcode api example app is working for EAN-13 when ever I tested the application in the device. So try to check the app in the device if you are unable to get the correct result in the simulator.

 

 

Thanks,

Re: barcode example not working

Late post but hopefully it helps future developers:

 

You will need to modify the code because the "display" and "scan" buttons for the Torch are "touch screen" buttons.

Since the Bold's screen is just a screen, the display and scan buttons need to be converted into buttonfields, here's an example:

 

_mainScreen.setTitle("Barcode Scanner");

ButtonField scanButton = new ButtonField("Scan Barcode", ButtonField.CONSUME_CLICK | ButtonField.NEVER_DIRTY |

Field.FIELD_HCENTER | Field.FIELD_VCENTER);

scanButton.setCommand(new Command(new CommandHandler() {

public void execute(ReadOnlyCommandMetadata arg0, Object arg1) {

scanBarcode();

}

}));

_mainScreen.add(scanButton);

 

Hope that helps,

 

James

Re: barcode example not working

I had problems too with the BarcodeScanDemo in the JDK 6.0... it worked fine in the simulator, but didn't work on a real Torch device.

 

But when I tried BarcodeAPISample in http://supportforums.blackberry.com/t5/Java-Development/How-to-use-the-Barcode-API/ta-p/574569  it worked fine in a Torch device and in the simulator.

 

(I only tested QR code scanning)
