title: gradle dependency error in android
body: <p>In the following build.gradle, I added the configuration section to avoid double inclusion of support libraries. Support libraries are used in the main project and in the dependent projects like facebook sdk. Without the configuration section, I get "UNEXPECTED TOP-LEVEL EXCEPTION". Adding that configuration makes the error go away and the app all works fine.</p>
  
  <p>Now, I'm trying to add RecyclerView to my app and I get RecyclerView class not found while inflating the recyclerview (although it builds ok). If I remove the facebook SDK and configuration section, the recyclerview works just fine.</p>
  
  <p>Question: What changes can I make to the build.gradle to make the facebook SDK work and RecyclerView work? In other words, why is the config section excluding v7 when it is only supposed to exclude v4?</p>
