How do i set the download destination of my WebView to the Downloads folder without knowing the name of the file?

I have the following problem:

I have a WebView. This WebView has a download listener that acts when the user is trying to download a file.

I want the file to be downloaded to the regular "Downloads" folder. I can do this by using

request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, title);

But how do I save the file under its original name?

I can't use

String name = URLUtil.guessFileName(url, null, mimetype);

Since the url that is being called does not contain the filename.

My download manager currently looks like this:

mainWebView.setDownloadListener(new DownloadListener() {
        public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
            DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
            // Show a download notification
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
            DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
            String title = URLUtil.guessFileName(url, null, mimetype);

            // Set directory of where the file should be saved to
            request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, title);
            // Start the download
            dm.enqueue(request);
        }
}

Note: I am currently using the URLUtil.guessFilename() Method because that will allow me to save my file, event if it's under the wrong name.

SOLUTION

The solution was passing the proper contentDisposition to the URLUtil.guessFileName() Function.

Getting the title works like this:

String title = URLUtil.guessFileName(url, contentDisposition, mimetype);

(All parameters are passed into the public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength))
