I used ActionBar Style Generator, and now trying to use into my app, but getting :
error: Error retrieving parent for item: No resource found that matches the given name '@style/ Theme.AppCompat.Light.DarkActionBar'.
i am using android-support-v7-appcompat.jar lib inside libs folder
my target is to make my app compatible 2.3 or above
AppCompat
is a library project. You need to reference the library project in your android project.
Check the topic Adding libraries with resources.
Update
Adding material theme should be the way. Check https://material.io/develop/android/docs/getting-started for more details.
