On first use you can detect if a given package is installed, thereby
detecting your previous app. I don't know about uninstalling another
app, all I can think of is a hack. You could have have the new
version encourage the user to remove the old one, and provide a link
to a new version APK for the demo app that is a thin shell. It would
replace the previous demo with a near empty application that just
opens the full app.
