NoClassDefFoundError when using Parse.com to login to Facebook

Question

I am currently using parse.com as a backend solution for my Android app. I am trying to use Facebook to authenticate users and I'm currently experiencing the errors below. I have tried to add both JARS (Parse and Facebook) to my project. I have also cleaned my project several times but I still get the errors below :
