I have been trying to find a solution for this and its been a while now
this is the directory I am using
let options = {
fileCache: true,
addAndroidDownloads: {
useDownloadManager: true,
notification: true,
title: fileName,
path: fs.dirs.DownloadDir + `${name}`, // Android platform
description: 'Downloading the file',
},
};
for this path fs.dirs.DownloadDir , I am expecting that the file destination would be Downloads folder but instead it goes to Documents -> Download as shown below
