An app currently saves files to "mydir" on the internal memory:
Instead, I want the files saved onto external memory card, but I am unable to figure out what is the right path. The attempts below do not work:
/SanDisk SD card/mydir
/storage/SanDisk SD card/mydir
/storage/emulated/SanDisk SD card/mydir
Android 9 , Redmi 8
"SanDisk SD card" comes from a file manager app, not sure if the card is to be specified by this or something else.
