if the url is null, you should also probably finish.

Done.

ah with the activity style that I mentioned, I think you'd not get the buttons
that you want, so I don't think that recommendation was good.  This is probably
what you need to do.

You'll want to use a different activity theme though.  I think you want
@android:style/Theme.Translucent.NoTitleBar

Also, here is where you should use R.style.AlertDialogTheme, it should be the
second param to the builder constructor.

Done.
