I try to replace WebView with GeckoView for multiple reasons but also to mitigate the problem that Android 4.4 won't call openFileChooser anymore to handle file uploads.
Unfortunately, I couldn't find out how I can handle file uploads in GeckoView. When I tap on a button that would trigger it, nothing happens and none of the callbacks I tried implementing work.

Any suggestions?
