  你查看Sample中的MediaFileDetailsFragment.kt文件中有关于下载的完整方法，你需要手动打开文件，写入，关闭文件。

  fun downloadFile(){
      val dirs: File = File(DiskUtil.getExternalCacheDirPath(ContextUtil.getContext(), mediaFileDir))
      if (!dirs.exists()) {
          dirs.mkdirs()
      }
  
      val filepath = DiskUtil.getExternalCacheDirPath(ContextUtil.getContext(), mediaFileDir + "/" + mediaFile?.fileName)
      val file: File = File(filepath)
      if (file.exists()) {
          file.delete()
      }
      val outputStream = FileOutputStream(file)
      val bos = BufferedOutputStream(outputStream)
      var beginTime = System.currentTimeMillis()
      mediaFile?.pullOriginalMediaFileFromCamera(0 , object :MediaFileDownloadListener {
          override fun onStart() {
              showProgress()
          }
  
          override fun onProgress(total: Long, current: Long) {
              updateProgress(current , total)
          }
  
          override fun onRealtimeDataUpdate(data: ByteArray, position: Long) {
              try {
                  bos.write(data, 0, data.size)
                  bos.flush()
              } catch (e: IOException) {
                  LogUtils.e("MediaFile" , "write error" + e.message)
              }
          }
  
          override fun onFinish() {
              var spendTime = (System.currentTimeMillis() - beginTime)
              var speedBytePerMill : Float? = mediaFile?.fileSize?.div(spendTime.toFloat())
              var divs = 1000.div(1024 * 1024.toFloat());
              var speedKbPerSecond : Float?= speedBytePerMill?.times(divs)
  
              ToastUtils.showToast(getString(R.string.msg_download_compelete_tips) + "${speedKbPerSecond }Mbps"
                      + getString(R.string.msg_download_save_tips) + "${filepath}"  )
              hideProgress()
              try {
                  outputStream.close()
                  bos.close()
              } catch (error: IOException) {
                  LogUtils.e("MediaFile" , "close error$error" )
              }
          }
  
          override fun onFailure(error: IDJIError?) {
              LogUtils.e("MediaFile" , "download error$error" )
          }
  
      })
  }
