Absolutely. It's part of the bedrock of Android itself -- the ability
to code to higher API levels yet run them on older devices, so long as
you don't try *executing* anything that is too new (though the story
gets a bit more complicated for Android 1.x). I do it every damn day
and twice on Sundays. :-)

There are certainly places where just handling the runtime exception
is OK (e.g., ActivityNotFoundException), but I wouldn't do that here.
