The style generator creates a theme for ActionBar tabs. The ViewPager looks similar but requires a different set of defined styles. You can find examples for the ViewPagerIndicator styles here:

Alternatively, you can use the styles created from the style generator by using ActionBar tabs instead of the ViewPagerIndicator.
