This seems is a mismatch on the Google Android Support libraries , you need to make sure that you have installed the correct version of the support libraries, the ones that Forms uses. You could have other library that request a different version and it can also cause this issues.

Make sure you remove all packages and add the latest stable version of forms. Clean, and rebuild.
