/mnt/sdcard empty folder in this location
/sdcard empty folder in this location
storage/sdcard no such location
data/media/0/Pictures files added, but can’t access from galley
devtools -> media scanner/media provider also I don’t have this options inside my emulator.
You can send any file into android emulator via drag-n-drop action.
And then go to Settings – Storage and re-mount your sdcard.
