title: Gradle error: package com.facebook does not exists for android studio
body: <p>I'm again lost in this facebook login part for my app. Well what happen is that I downloaded the facebook SDK from the facebook site itself then used eclipse to export the project with gradle to be used for android studio. Now in the project stucture of my main app in android I imported the Module of the facebook that I converted then on dependencies I add the module dependency of facebook in my main app. Now I tried to import the facebook package and it just works fine in my MainActivity. Now after I tried to run it errors appears see screenshot:</p>

  <p>I tried using the ./gradle clean for both projects and it cleans just fine but I get an error for the build part. I think something went really wrong after I exported the facebook project in gradle structure. How can I solve this error? Anyone encountered this?</p>
