Download option with WebView

Unfortunately, I have lost my old access data and cannot continue.

I would like to have a download option with WebView.
Since I do not know the files (zip. Pdf, apk) etc. I can not make a default.
With the old account I had saved a working example but unfortunately not on the PC.
I need a block view once so that the app can also start downloading all files from the Internet.
The example of “Omkaraffiliates” does not seem to work anymore because I cannot select “global SplitdownloadURL”.
