My code

 startDownload(item) {
        var ext = this.getExtention(item.title);
        let nameId = item.name
        let urls = item.title
        ext = '.' + ext[0];
        let dirs = RNFetchBlob.fs.dirs.PictureDir
        let fileName = `GIFs__(( '${item.id}))__ ${new Date()} ${ext}`;
        console.log(urls.toString())
        let task = RNBackgroundDownloader.download({
            id: nameId.toString(),
            url: urls.toString(),
            destination: `${dirs}'/'${fileName}`
        }).begin((expectedBytes) => {

            console.log(dirs + fileName)

            let newResult = this.state.files

            newResult.filter((mainFile) => {
                if (mainFile == item) {
                    console.log(mainFile)
                    return mainFile
                }
            }).map((value) => value.is_downloading = true);

            this.setState({ files: newResult })

            console.log(`Going to download ${expectedBytes} bytes!` + item.id);

        }).progress((percent) => {

            console.log(`Downloaded: ${percent * 100}%`);

        }).done(() => {

            this.setState(prevState => ({
                files: prevState.files.filter(newitem => newitem.id !== item.id),
            }));

            console.log('Download is done!', item.id);

        }).error((error) => {
            console.log('Download canceled due to error: ', error);
        });
    }

Hey @kp72-dev, I've got this issue today. Was able to solve it by updating the AndroidManifest file to add this:

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:requestLegacyExternalStorage="true" //Add this Line
    android:label="@string/app_name"
>

    ---------<Activity, Sevices or Recivers>----------

</application>

Hi, I'm facing this issue too.
on android 7 nox emulator everythings works fine but on a real android 11 device it keeps throwing UNKNOWN_IO_ERROR
I set the android:requestLegacyExternalStorage="true" , checked my permissions and logged my url and destination path but its not working.
Any idea about this?

Im using react native 0.63.3 if you need more information please do inform me.

[armata99]

as they mentioned here the fetch library has to be updated to become compatible with android 11.
after that there might be some reviews needed for this library too.
