标题: 文件下载失败

设备: Phantom 4 RTK.操作:下载图片.
说明: 拍照时我把文件信息存了起来,包括fileName,size,index,fileType,然后自己构造成mediaFile,camera设置成了download模式,然后调用mediaFile.fetchFileData()方法. 难道是设备不支持下载文件吗?
执行结果:"=======>onFailure"Not Support"

具体代码:

/**
* 下载文件帮助类

public class DJIDownloadMediaFileUtil {
String TAG = this.getClass().getSimpleName();

public void downloadMediaFile(EntityWaypoint entityWaypoint) {
      MediaFile mediaFile = new MediaFile.Builder().fileName(entityWaypoint.getFileName()).fileSize(entityWaypoint.getFileSize()).index(entityWaypoint.getFileIndex()).downloadedSize(entityWaypoint.getFileDownloadSize()).mediaType(MediaFile.MediaType.find(entityWaypoint.getFileType())).build();
      if (mediaFile == null) {
         LogUtil.logInfo(TAG, "=======>mediaFile == null");
         return;
      }

      LogUtil.logInfo(TAG, "=======>fileName:"+entityWaypoint.getFileName()+"fileSize:"+entityWaypoint.getFileSize()+",fileIndex:"+entityWaypoint.getFileIndex()+",downloadedSize:"+entityWaypoint.getFileDownloadSize()+",mediaType:"+entityWaypoint.getFileType());
      Camera camera = DJIProductUtils.getCameraInstance();
      if (camera == null) {
         LogUtil.logInfo(TAG, "=======>camera == null");
         return;
      }
      MediaManager mediaManager = camera.getMediaManager();
      if (mediaManager == null) {
         LogUtil.logInfo(TAG, "=======>mediaManager == null");
         return;
      }
      String rootPath = Environment.getExternalStorageDirectory().getPath();
      String dataTimeStr = entityWaypoint.getDataTime();
      dataTimeStr = dataTimeStr.replaceAll("-", "");
      dataTimeStr = dataTimeStr.substring(0, 8);
      String filePath = entityWaypoint.getLineName() + File.separator + entityWaypoint.getTowerName() + File.separator + dataTimeStr;
      filePath = filePath.replaceAll("#", "");
      File destDir = new File(Environment.getExternalStorageDirectory().
            getPath() + "/IntelligentPatrol/" + filePath);
      LogUtil.logInfo(TAG, "=======> fileName:" + entityWaypoint.getFileName());
      if (!destDir.exists()) {
         destDir.mkdirs();
      }
      LogUtil.logInfo(TAG, "=======>" + destDir.getAbsolutePath());
      camera.setMode(SettingsDefinitions.CameraMode.MEDIA_DOWNLOAD,
            new CommonCallbacks.CompletionCallback() {

                     } else {
                        LogUtil.logInfo(TAG, "=======>camera.setMode MEDIA_DOWNLOAD fail " + djiError.getDescription());
                     }
                  }
            });
      mediaFile.fetchFileData(destDir, entityWaypoint.getFileName(), new DownloadListener<String>() {

         @Override
         public void onStart() {
            LogUtil.logInfo(TAG, "=======>onStart");
         }

         @Override

P4R不支持获取原图片fetchFileData，仅支持获取高清预览图。
