My app is actually opening the Google Goggle app rather than the Barcode Scanner app from zxing! I have now installed the correct Barcode Scanner app, and it works. Many thanks all!
Reading 3 of 9 extended bar codes using zxing - in Android

Frage
I am working on replacing an expensive set of bespoke bar code readers with a nice and simple android app.
I am calling the zxing package, and am able to read most bar codes, apart from Code 3 of 9 extended, which is the current standard barcode in our business (with over 2000 barcodes already in circulation).
Is there a way of extending the zxing package to include Code 3 of 9 Extended bar codes??
My current code, which opens the google goggles app and successfully displays QR code and most 1D barcodes information via a Toast call, and I have tried explicitly defining which codes to read but have commented that line out as without it, the scanner should read all possible codes (just for testing):
mGetScanButton = (Button) findViewById(R.id.buttonScan);
mGetScanButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
//intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR,EAN_13,EAN_8,UPC_A,QR_CODE" );
startActivityForResult(intent, 0);
}
});
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
// The Intents Fairy has delivered us some data!
String contents = intent.getStringExtra("SCAN_RESULT");
//code below will be deleted after testing
//String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Toast call to display code when read
Toast.makeText(this, contents, Toast.LENGTH_LONG).show();
// Handle successful scan
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel
}
}
}
Your assistance is much appreciated, I would prefer not to ask the staff to replace all the bar codes... although this may be required!
Example of Code 39 extended - encoded number = 25
