Hi, Use File.separator instead of /.
This might be obvious but make sure SD card is not mounted on PC when running your code & debugging. Yes Context Provider is 'best' particularly for sharing with other apps, but involves a lot more work. Also I would not bother to check if file exits & create it I would just write to it regardless unless you don't want to overwrite it.
