如何使用react native下载android中datadata[应用程序包名称文件夹]files中的文件

当我试图下载文件时.它不是存储在路径/data/data/[Application Package name folder]/files中，而是在/storage/emulated/0/Android/data/[Application Package name folder]/files中下载.

我试过使用rn-fetch-blob套餐和react-native-blob-util套餐.我收到的错误是不受支持的路径.作为参考，我附上了错误屏幕截图

Below is the code I have written for download个

const downloadRecord = async () => {
  let FILE_URL = `https://www.africau.edu/images/default/sample.pdf`;

  let file_ext = getFileExtention(FILE_URL);
  file_ext = "." + file_ext[0];
  let extension = file_ext;
  let date = new Date();
  let Name = bookID; // + Math.floor(date.getTime() + date.getSeconds() / 2);

  try {
    const { config, fs } = ReactNativeBlobUtil;
    const DownloadDir =
      Platform.OS == "ios"
        ? `${fs.dirs.LibraryDir}/name/`
        : `${fs.dirs.DownloadDir}/name/`;
    let fileName = Name + extension;
    let pdfPath = DownloadDir + fileName;
    console.log("Path", pdfPath);
    let options = {
      fileCache: true,
      addAndroidDownloads: {
        //Related to the Android only
        useDownloadManager: true,
        notification: true,
        path: pdfPath,
        description: "downloading...",
      },
      path: pdfPath,
    };

    //console.log(FILE_URL)
    config(options)
      .fetch("GET", FILE_URL)
      .progress((received, total) => {
        console.log("progress method", (received / total) * 100);
      })
      .then((res) => {
        //console.log('res -> ', JSON.stringify(res));
      })
      .catch((error) => {
        Toast.show("Error downloading Training Record.");
      });
  } catch (error) {}
};
