WebView wont allow fileupload

The current webview implementation does not allow  file upload via
HTML <input type="file"> tags.

I have created a patch that overrides onShowFileChooser  of WebChromeClient

used in WebView.

 
 
https://developer.android.com/reference/android/webkit/WebChromeClient#onShowFileChooser(android.webkit.WebView,%20android.webkit.ValueCallback%3Candroid.net.Uri[]%3E,%20android.webkit.WebChromeClient.FileChooserParams)
 
And it seems to work.
But this implementation requires startActivityForResult  with intent Intent.ACTION_CHOOSE
and a matching onActivityResult implementation. As a result it requires more work on
part of developer to  use a custom class in place of QtActivity for the main activity
of app. The custom class is required so that onActivityResult can be overridden.
 
Are there better ideas to implement it?
 
I explored Fragments inside QtAndroidWebViewController.java but it seems to
require android support package or androidx.
