Project properties are the same for my app and the appcompat v7 too. The target is set to 21 for both appcompat and my app . The error was at styles_base and later after following some answers it jumped to themes base. I had even reinstalled java and eclipse.

Please what should I do?

Build your project with the API 21 SDK to Let your project know about resource for API 21. Don't forget to clean and re-build.
