Removing directory on uninstall

Hi,

I created a Flex mobile app. When a user installs the app, the data which
is stored as an xml file in Google drive downloads to the sdCard in mobile.
Then the xml file is read and the data is stored in sqlite dataBase. After
database creation, the xml file is deleted.

So the folder now contain only a db file.

If a user uninstalls the application, Is it possible to delete the folder
which contains the db file?
