4 years ago I tried this out, but it has some significant drawbacks:
- The URIs returned by the dialogs use the content scheme, which allows you to access the file content as a stream but doesn't allow you to get the filesystem path of the file. This is a pretty critical limitation, given that Metakit generally requires the path in order to open the file. This could be worked around by copying the file content to a known location before opening it, but this adds an assortment of synchronization problems (especially when reopening a file from the recent files list).
- While the file dialog is "native", it isn't one I've seen in any other apps and doesn't seem to respect the system theme. The default mode uses a lot of screen real estate per file, requiring a lot of scrolling (and it doesn't seem to remember changes to the view mode between launches). This seems likely to be even worse for usability than the hacked layout of QFileDialog that PortaBase currently uses on Android.
I could probably hack something together to make the native dialogs work, but it doesn't seem worth it right now. I'll check again if they make improvements to it in future Qt releases or the current filesystem access mechanism stops working in future Android releases.
Qt 5.15 is now out, supposedly with support for native file open and save dialogs on Android. Try this out and see if it's an improvement on the dialog used in the 2.2 release.
