android - How to add support libraries?

Question

I added android-support-v7-appcompat. Next I clicked on each file in directory libs. Then I clicked android-support-v7-appcompat and opened properties. Next checked files from directory libs and unchecked Android Dependencies. Next opened properties of myproject. Went to the projects and by Add button added android-support-v7-appcompat.

But nothing is working. How can I make ActionBarActivity(there is no new variants) and how can I add a theme. I used to add in manifest to activity, tried to add it to the style.xml

I acted in wrong way. It is below.
