Yes, and there are other methods for creating databases, getting paths, etc. > I have tried these methods.They create file under /data/data/<my > package>/files/ directory.

Otherwise its data is left laying around for the user to manage. Maybe in the future we will have a UI option to uninstall an app but keep its data (the package manager can already do this), but this leads to a much more complicated user experience so it is a low priority. > Is there a directory or method to keep the file even if the user > uninstall my app ,so that I can find previous infomation about my app > when user install my app again. No, sorry. Uninstalling is supposed to clean up everything of the app. -- Dianne Hackborn Android framework engineer [email protected] Note: please don't send private questions to me, as I don't have time to provide private support.
