Your SQL open helper probably has something like:
private static final int DATABASE_VERSION = 1;
used like this (funky emphasis mine):
public YourDbOpenHelper(Context context) {
super(context, DATABASE_NAME, null, [[[--->>> DATABASE_VERSION
<<<---]]]);
}
The database version value is stored inside the SQLite database, and is
compared to the value in your code. If the value in the code is greater,
your onUpgrade is called. This logic is contained in the
SQLiteOpenHelper constructror (the call to "super" above).
So, to test your onUpgrade, first run your application and make sure
that database is opened. This will store "1" (or whatever current value
of the constant is) as the database version.
Now increment the version number to a greater value than used before.
Then run your application, and make sure you work with the database.
It's not necessary to use "adb install", just running from Eclipse for
debugging, as usual, will work fine.

I haven't tried to debug this. Most of the DB upgrades will simple
enough, which didn't need explicit debugging. But, it works. I am sure
it works on the emulator, and it should work on the device as well.

Thanks anyway.
If I use the mobile device I can't use adb install because it says its
installed. If I use the -r parameter with adb install it make a new
installation from scratch so no upgrade event is fired.
Have you ever tried to do with the device not with the emulator?
