Cordova Can’t save files inside root folder

Question

I’m trying to save it in the briefcase Download in the root do dispositivo Android, but do not access it and the file is not created, not even if I create directory.

In the Cordova documentation you ask to use LocalFileSystem.PERSISTENT , but I still can’t access the system root.Even if I type manual the location :file:///storage/emulated/0/,still cannot access and generate any file.

Current code that saves in file:///storage/emulated/0/Android/data/io.ionic/files/

    window.resolveLocalFileSystemURL(cordova.file.externalDataDirectory , function (dir) {
    // dir.getDirectory('images', { create: true }, function (subDirEntry) {});
    dir.getFile(fileName, { create: true, exclusive: false }, function (fileEntry) {
        fileEntry.createWriter(function (writer) {
        writer.onwrite = function (evt) {
            Swal.fire({
            icon: 'success',
            text: `${fileName} foi salvo na pasta ${cordova.file.externalDataDirectory}`,
            showConfirmButton: true
            });
        };
        writer.write(fileData);
        })

    }, function () {
        Swal.fire({
        icon: 'error',
        text: `Houve algum erro ao gerar o pdf , tente novamente`,
        showConfirmButton: true
        });
        });
    });
}

And in itself config.xml preferences to access are set for various folders

<preference name="iosExtraFilesystems" value="library,library-nosync,documents,documents-nosync,cache,bundle,root" />

<preference name="AndroidExtraFilesystems" value="files,files-external,documents,sdcard,cache,cache-external,assets,root" />
