title: How to trigger Bulk scan mode using Zxing library in my app to scan multiple barcodes and qrcodes without showing a preview screen
body: <p>Can anyone help me to achieve Bulk Scan Mode using Zxing library inside my app. What it does now is that after scanning a barcode the camera screen disappears and the scan result is populated on my Activity. But I need to do is scan multiple barcodes one after the other and then return back to my activity on back button press.</p>
