Any suggestions on how to test upgrade between versions? I need to be sure
my application can handle being upgraded from any version released on
market.

Currently I'm doing *adb shell pm uninstall -k* to remove the old program,
and run adb install with the new version. This method sucks because it's a
lot of manual work. On top of that I'm not even 100% certain this method
acts the same way market does upgrades.

I use Sqlite and have unit tests which covers upgrading from any database
versions, so I'm sure this is covered. But is there anything else I need to
worry about?

I experienced loss of shared preferences when doing an upgrade this way.
That is is very serious for my app as I keep a flag in shared preferences
for knowing if this is a clean installed phone or not. If it's clean it
starts loading default data into the app. This creates duplicates and a
mess.

All tips and suggestions will make me wanna marry you,
Finn
