i have a base class "BaseActivity" and a class that dervies from
TabActivity.

I am doing a bunch of stuff in BaseActivity -- esp. in the overriden
methods so I can avoid having to do it in all my activities
("generalize and promote").

I am finding it a bit of a pain that I have to make all those same
changes/fixes/updates in my TabActivity class as well (since I can't
really change that TabActivity derives from Activity instead of
BaseActivity).

Any thoughts on how to do this better?

tia.
