Regression 5.15: Sharing Files w FileProvider fails

With Qt 6.6 QDesktopServices is supported using qtprovider (FileProvider).

This works great !

In some Apps I'm already using a custom FileProvider to share Files with other Apps. This worked well in 5.15.

Now in 6.6 I have both FileProviders in Android Manifest:

• android:authorities="${applicationId}.qtprovider"
• android:authorities="org.ekkescorner.examples.sharex.fileprovider"

and also metadata in XML Resource with different FilePaths:

• for qtprovider I changed file path from "/" to: "my_special_files/" to avoid any overlapping pathes
• my custom FileProvider uses file path "share_example_x_files/".

QDesktopServices works well for files inside "my_special_files/".

Trying to share Files lists Android Chooser with valid target Apps for VIEW, EDIT or SEND. But when I'm selecting an App - per ex. Google Files, my provided File cannot be displayed, because of an error:

The authority org.ekkescorner.examples.sharex.fileprovider does not match the one of the contentProvider: org.ekkescorner.examples.sharex.qtprovider
at android.content.ContentProvider.validateIncomingAuthority(ContentProvider.java:2568)

at android.os.Binder.execTransactInternal(Binder.java:1280)
at android.os.Binder.execTransact(Binder.java:1244)

I disabled the qtprovider in Manifest - then sharing works as before, but then of course QDesktopServices isn't working. I would prefer to be able to use both: File Sharing and QDesktopServices
