hello ,when i use this lib chose a folder and react-native-fs to downloadFile, i get this error:

err Error: ENOENT: no such file or directory, open 'content://com.android.externalstorage.documents/tree/15F4-2D1A%3ADownload/document/15F4-2D1A%3ADownload/'

there is my code:

selectDirectory().then((path) => {
                console.log(path);
                //
                const downloadDest = `${path}/`;
                //
                const options = {
                    fromUrl: url,
                    toFile: downloadDest,
                    background: true,
                    begin: (res) => {
                        console.log('begin', res);
                        console.log('contentLength:', res.contentLength / 1024 / 1024, 'M');
                    },
                    progress: (res) => {
      
                        let pro = res.bytesWritten / res.contentLength;
                        console.log('pro==', pro);
                    },
                };
                try {
                    const ret = RNFS.downloadFile(options);
                    ret.promise
                        .then((res) => {
                            console.log('success', res);
                            console.log('file://' + downloadDest);
                        })
                        .catch((err) => {
                            console.log('err', err);
                        });
                } catch (e) {
                    console.log(e);
                }
            });

can i get any help?

My environment is Android, simulator

Unfortunately, the method we're using for directory picking is based off of SAF. While this works for some instances, RNFS does not support SAF at the moment (to the best of our knowledge).

This library is in severe need of documentation - it's something on our todo list that explains the limitations, real-world usages, and future roadmap

In the meantime, however, I would suggest against using this library. Maybe I can point you towards how we're using a non-SAF directory picker in our app, GitShark?

Android

For Android:

• We're using a forked version of the MaterialFilePicker library that supports non-SAF directory picking (which does work with react-native-fs). To set this up, you need to add:
  • The JitPack repository in your build.gradle
  • The dependency in your app/build.gradle
• Then, we create a Java file that contains the relevant code to call that library in a way you might expect
• Finally, we call that Java file from within React

iOS

However, for iOS, we found that it was not advantageous from a UX perspective to implement a directory picker (again, for a myriad of reasons that will be in the future blog post). Instead, for our usage we simply drop files into our app's directory and disallow users to select folders. This requires two changes:

1. An Info.plist change
2. Use DocumentDirectoryPath as the base path for any iOS files:

import {DocumentDirectoryPath} from 'react-native-fs';

const filePath = `${DocumentDirectoryPath}/folder/file.ts`;

Full example

This way, they're accessible from the Files app easily without too much development hastle

will ~ thx .
Actually I don’t have any native development experience.
Maybe i will find other lib. ahahahah
Finally, thank you again.
