Is it possible to receive file-operations events happening inside a folder under Storage Access Framework into an Android app?
I mean, a folder that was selected by the user, and thus authorized.
The app has the corresponding uri in a suitable form.
When a file is modified, created or removed inside that folder an event should reach the Android app back, even if this time no operations were performed by the app itself or from the device in use.
Is this possible?
