I agree with what @codercat has advised you to do, but this error also comes when you are using v7 and also v13 in the same project structure for different functionalities. Therefore, i advice you to copy the v13 jar file into the libs folder (DO NOT import it as an external jar) and then check the android libraries and android dependencies. Refresh you project and then clean your project. I am sure the error you are facing will go away.
