Is it possible to start another scan session after a barcode has been scaned?

[roostaamir]

Hi and thank you for your great library I am using the BarcodeCaptureFragment to initiate a scan session. I want to initiate the scan session on activity create (therefore I am adding the fragment to the activity in the onCreate method), and then when a barcode has been scanned, show the user a dialog, and when the user clicks the button on the dialog (I set the setCancelable to false), the dialog should be dismissed and the barcode scanning process should begin again

What I have done so for is this:

barcodeCaptureFragment.setListener(new BarcodeCaptureFragment.BarcodeScanningListener() {
            @Override
            public void onBarcodeScanned(Barcode barcode) {
                new AlertDialog.Builder(MainActivity.this)
                    .setMessage(String.format("DisplayValue is : %s\nRaw value is : %s", barcode.displayValue, barcode.rawValue))
                    .setPositiveButton("close", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            dialogInterface.dismiss();
                        }
                    })
                    .show();

            }

            @Override
            public void onBarcodesScanned(List<Barcode> barcodes) {

            }

            @Override
            public void onBarcodeScanningFailed(String reason) {

            }
        });

The problem is that when a barcode is scanned, the dialog will be shown, and the camera will freeze and will not scan anything else unless I close the activity and open it again I could remove the fragment and add it again, but this does not seem to be a good approach Any suggestions on how I can do this?

This is not readily available. But should be possible. You can try overriding void onBarcodeDetected(final Barcode barcode) if you are using SINGLE_AUTO mode, and comment out the mCameraSource.stop() line. Or you can try calling void initiateCamera() after the dialog is closed.

instead of changing your code, I used reflection to call initiateCamera method and it worked for me. Thank you

exactly.I did the same. Method initiateCam = BarcodeCaptureFragment.class.getDeclaredMethod("initiateCamera"); initiateCam.setAccessible(true); initiateCam.invoke(fragment);
