Переместить файл из временной папки во внешний каталог, не работающий на устройстве Android 8 и выше

Question

Я использую плагин IonicMultiCamera, плагин CameraPreview и 'cordova-file-plugin' для захвата и перемещения изображений из кэша в указанную папку в externalRootDirectory.Этот процесс хорошо работает в Android версии 7 и ниже, но не работает в Android версии 8 и выше.

Для Android версии 8 и выше функция 'moveFile' 'cordova-file-plugin'выдает ошибку как: {code: 1, message: 'NOT_FOUND_ERR'}.

          this.storeimages.push(this.storedfilepathname);
          console.log('storeimages'+JSON.stringify(this.storeimages)+'uuuuuuu'+this.storedfilepathname);

          this.file.readAsDataURL(filepathnew, newFileName).then(dataurl => {
            this.lastImage = dataurl;
            this.finalimages.push({src:this.lastImage});
            console.log(" finalimages "+JSON.stringify(this.finalimages));

          console.log("copyFileToLocalDir"+newFileName);
        }, error => {
          console.log('storeerror='+JSON.stringify(error));
          this.presentToast('Error while storing file.');
        });
      }

Путь к каталогу, куда я хочу скопировать изображения, может быть "this.file.externalRootDirectory + 'Customervisitingcard / '";
