I doubt this will be resolved anytime soon. It's a big change.
This breaks several modules across the python android development chain as they need to be updated to use FileProvider

Accessing the URI path (storagepath.get_downloads_dir() etc...) throws this exception.
Have this issue on Android version 9
Yeah sucks that Google is making it so difficult for developers...
There are workarounds though, but they're far from ideal.

Technically it is possible to add file provider to p4a, I have made a pr some time ago: kivy/python-for-android#1922 it would help to progress it if you could test it for your app

What is the hold up with kivy/python-for-android#1922 (17 months since created) or kivy/python-for-android#2200 (7 months since created) ?

p4a is 3 years behind Google in supporting Android features that depend on FileProvider.

What is the hold up with kivy/python-for-android#1922 (17 months since created) or kivy/python-for-android#2200 (7 months since created) ?

those are waiting on kivy/python-for-android#2020
