An uninstall/install cycle will wipe the SQLite db and the
preferences. The only (reasonable) way to keep user data is through an
upgrade. You can test an upgrade by posting the new version (new apk
file) on a web site of yours and install it as a non-market app
through Android's browser. Once the download begins, the process of
installing the app converges.
Posting on a web site needs the following MIME setting there:
application/vnd.android.package-archive
