I was using Theme.Holo as parent in my application before trying to target lower versions of Android OS. To adapt my application to older versions, I have to use ActionBarSherlock library. But it requires the theme of the application be one of ActionBarSherlock's own themes (Theme.Sherlock.Light.DarkActionBar instead of Theme.Holo).
I still need to use Theme.Holo. But it is not possible by default.
Are there any modifications done do make this happen?
