How about adding support for SAF (Storage Access Framework)?

[Typhonling]

With SAF you can view non-local files.
Also with SAF you can add non-local folders, e.g. with CIFS .

Adding network protocols may be complex and bloat the application, SAF is the system framework and only needs to be called locally, which may make things easier. This way we can get rid of BubbleUPnP even more. Kodi is too bloated and difficult to use on a touch screen.

Possibly related to #124

Do you mean select a local file using SAF and stream it to the current receivers? That might be possible, I have to take a deeper look how it could work

Simply put, I hope I can manually add the folders from SAF that need to be scanned.

Currently the app only fetches what is in the android media store. The android system is responsible for the content in there. Therefore either the media store is able to scan network shares or yaacc itself needs to set up a data store for that information. I need to take a look, what might be possible
