I am using the Download Manager and when I use 

 setDestinationInExternalFilesDir(this, Environment.DIRECTORY_DOWNLOADS, "example.ext");

the files are downloaded to Android/data/com.example.app/files/Download folder.

When I try 

setDestinationInExternalPublicDir("/folder", "example.ext");

I get: IllegalStateException: Cannot create directory mnt/sdcard/folder. I've set the WRITE_EXTERNAL_STORAGE permission too.

What am I doing wrong?
