Hybrid and SQLite files location on Android

In my Hybrid apps i can create without problem SQLite DB inside the private Application folders.
Now i need to position the files in public folders accessibile from file management apps (at the same level of DCIM folder)
With Android.OS.Environment.ExternalStorageDirectory i can get the path for External Storage
But when i try to open/create the SQLIte file i got an error that the file is not accessible.
