Use the Android default DownloadManager to download files in the background. It will open the system download list when you click on the notification.
const dmg = require("com.miga.downloadmanager");
let url = "https://....file.zip";
let filename = url.substring(url.lastIndexOf('/') + 1);
dmg.startDownload({
url: url,
filename: filename,
success: onDone,
title: "Download",
description: "Download " + filename,
target: "downloads" // podcasts, documents, downloads (default)
});
function onDone(){
alert("done");
}
