Is there a way to find out the path of files from a microSD card that is inserted into any Android phone?
From here, How to specify the directory path on external memory card? , it seems like the problem was solved, using an unspecified app that pointed to the right direction. (implying a tool can exist for that purpose)
From here, How to save files to external SD card on a non-rooted Android? , it implies
/storage/[UUID]/, but it wasn't clear how exactly to figure out that UUID.
