Qrcode is not valid

[MakeMeCookie]

I git clone the https://github.com/espressif/esp-idf-provisioning-android.git' site and succeeded in building Android. When you click Provision New Device and scan for QRCODE, the phrase "QRCODE is not valid" appears and does not go any further.

I checked the code and it looks like this part. I'd like to connect the qrcode to the ble, but how can I correct it?

/esp-idf-provisioning-android/provisioning/src/main/java/com/espressif/provisioning/ESPProvisionManager.java `@RequiresPermission(allOf = {Manifest.permission.CAMERA, Manifest.permission.BLUETOOTH_ADMIN, Manifest.permission.BLUETOOTH, Manifest.permission.ACCESS_FINE_LOCATION}) public void scanQRCode(final CodeScanner codeScanner, final QRCodeScanListener qrCodeScanListener) {

    formats.add(BarcodeFormat.QR_CODE);

    codeScanner.setDecodeCallback(new DecodeCallback() {
        @Override

            String scannedData = result.getText();
