Hi,
I have implemented a FileProvider in my Android app to edit PDF/DOCX files and call it from my Xamarin.Forms app via the dependency service.
The files I want to open reside in the private storage of my app.
Certain apps (like Google Docs) open the files in "write-mode", so that changes get saved in my private storage.
Other apps (like Microsoft Word and Adobe Reader) open the files read-only, although I am granting them full write access.
More details about my implementation can be found in this StackOverflow post:

Has anybody experienced similar issues?
