If you do this steps in Kotlin you can Download files from any WebView

1- Add these to your Manifest

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

2- Add these settings to your webview

val webViewSettings = binding.your@id@webview(InsideXML).settings webViewSettings.javaScriptEnabled = true //Needed webViewSettings.domStorageEnabled = true //Needed webViewSettings.allowFileAccess = true //Needed webViewSettings.loadsImagesAutomatically = true //Needed ----Yo can have more here but this are needed -----

3-Handle the downloads

//handle downloading binding.wvBase.setDownloadListener { url, userAgent, contentDisposition, mimeType, _ -> val request = DownloadManager.Request( Uri.parse(url) ) request.setMimeType(mimeType) val cookies: String = CookieManager.getInstance().getCookie(url) request.addRequestHeader("cookie", cookies) request.addRequestHeader("User-Agent", userAgent) // request.setDescription("Downloading File...") request.setTitle(URLUtil.guessFileName(url, contentDisposition, mimeType)) // request.allowScanningByMediaScanner() request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED) request.setDestinationInExternalPublicDir( Environment.DIRECTORY_DOWNLOADS, URLUtil.guessFileName( url, contentDisposition, mimeType ) ) val dm = getSystemService(DOWNLOAD_SERVICE) as DownloadManager dm.enqueue(request) alertdialog() }

In my case I have a custom alert Dialog to control if user says no, yes.
