QR-код сканер не запускает камеру в PhoneGap-приложении из на Adnroid'е?

Имеется PhoneGap-приложение.
Adnroid версия перестала открывать камеру для использования QR-код сканера, при этом на iOS всё прекрасно работает. Куда смотреть?

JS-код QR-код сканера:

function ticketScan() {
    cordova.plugins.barcodeScanner.scan(
      function (result) {
          if (result.format=='QR_CODE') {
              if (result.text) {
                  $$.get(getTokenUrl(result.text), function (data, status, xhr) {
                        data = JSON.parse(data);
                        if (data.mess) myApp.alert(data.mess);
                        if (data.notice) setNotice(data.notice);
                        if (data.html) {
                            $$('#scanner-result').html(data.html + '<br /><p><a href="#" onclick="$$(' + "'#scanner-result').html('')" + '" class="button">Очистить</a></p>');                            
                        }
                  });
              } else {
                  myApp.alert('Нет результата сканирования!');
              }
          } else {
              myApp.alert('QR-код не найден!');
          }
      }, 
      function (error) {
          myApp.alert("Ошибка сканирования: " + error);
      }
   );
}
