QR Code扫描不适用于Barcode Scanner

Question

I'm developing an android application for a tablet (model SynchroDigital INOSOP10-4.0 RES) and I'd like to use the ZXing library to scan a QRcode containing a string. It does launch the scanner when I need it but I can't scan anything.

Actually it doesn't even work if I use directly the Barcode Scanner application, the yellow dots appear but nothing happens, no matter the luminosity, the distance or the complexity of the QR Code (tried with a huge QR Code just containing the letter "A"), it just won't work.

Yet it works perfectly with another code scanner, the one from the pic2shop app !

The tablet's webcam is 1,3MP and doesn't have autofocus.

Does the issue come from the webcam ? Are there any others libraries I can easily implement instead of the ZXing one ?

Thanks in advance.

Answer 1

use below code, it will work for QR scanning, but it wouldn't work for barcode scan -

Intent objIntent = new Intent("com.google.zxing.client.android.SCAN"); 
objIntent.putExtra("SCAN_MODE", "QR_CODE_MODE"); 
startActivityForResult(objIntent, 0);

or use

Intent intent = new Intent(shopping.this, CaptureActivity.class);
startActivityForResult(intent, 0);
