Mark & Dianne,
Thanks for the replies. I was hoping there might some equivalent
of "adb install -r" that would allow my app to be re-installed without
losing its data (is it possible?). Unfortunately, the backup/restore
to SD card won't work for this app because the SharedPreferences
contains some sensitive data. It looks like I will have to go with
the plug-in approach.
Cheers,
Steve
