Java Development

Hi all,

          I'm a new to blackberry development and I'm trying to scan a Bar Code. The

below code snippet works fine for QR Code format but what I wanted is to scan a 

EAN 13 Bar Code, I just changed one line in the below code i.e.,

formats.addElement(BarcodeFormat.EAN_13);

 where the original code for QR Code is as depicted below

formats.addElement(BarcodeFormat.QR_CODE);

private void scanBarcode() 
{
	// If we haven't scanned before, we will set up our barcode scanner
if (_barcodeScreen == null) {
	Hashtable hints = new Hashtable();
	Vector formats = new Vector();
	formats.addElement(BarcodeFormat.EAN_13);
	hints.put(DecodeHintType.POSSIBLE_FORMATS, formats);
	hints.put(DecodeHintType.TRY_HARDER, Boolean.TRUE);
	BarcodeDecoder decoder = new BarcodeDecoder(hints);
try {
	_scanner = new BarcodeScanner(decoder, new MyBarcodeDecoderListener());
	_barcodeScreen = new MyBarcodeScannerViewScreen(_scanner);
} catch (Exception e) {
	log("Could not initialize barcode scanner: " + e);
	return;
}
}
try {
_scanner.startScan();
_app.pushScreen(_barcodeScreen);
} catch (Exception e) {
log("Could not start scan: " + e);
}
}

any help in this regard would be highly appreciated........

regards,

$aran.......

Hello, I needed to decode QR code and that code example worked well for me. I guess you should play with com.google.zxing.oned.* instead of com.google.zxing.qrcode.*

Up for this very interesting post.

I was able to decode at the same time QR and EAN_13 with the following code :

Hashtable hints = new Hashtable(1);
Vector formats  = new Vector();
formats.addElement(BarcodeFormat.QR_CODE);
formats.addElement(BarcodeFormat.EAN_13);
hints.put(DecodeHintType.POSSIBLE_FORMATS, formats);
// Initialize the BarcodeDecoder
BarcodeDecoder decoder = new BarcodeDecoder(hints);

The tips was to present the EAN_13 on a vertical way, it is not found on an horizontal one.

I tried to scan the EAN-13 code with my device with all possible directions. But i was enable to decode that code.

Finally i able to decode the EAN-13 barcode. But now i want to decode that string to actual data i.e. to which product it refers.

Like i have 5901234123457(Wikipedia EAN-13 image's output) as the result after decoding that EAN-13 code. But now can i use this code much further(like to which country it belongs, product name and more info).

Is it possible in BB ?
If yes, then please share.
