title: fresco can't be built by Gradle after imported into Android Studio
body: <p>We know the Facebook Technology Team open-sourced <code>fresco</code> about 5 days ago. And I git it from Github. And then I imported the whole project, afterwards I tried to build the <code>sample</code>, but AS can't make it. Errors are here:

  And:

  <p>And I have changed <code>gradle.properties</code> into this:</p>
  
  <pre><code>target=22

  </code></pre>
  
  <p>What's more, My Android Studio is 1.1.0, Gradle 2.2.1, ADT 22.
  I felt it's the matter of plugins with different versions. But I don't have a solution. So, could anybody help me or have any idea?</p>
