title: Butter Knife - Inject on Android lib
body: <p>I work on Android Studio with Gradle.</p>
  
  <p>My issue is <a href="http://tools.android.com/tips/non-constant-fields" rel="noreferrer">Non-constant Fields in Case Labels</a>.</p>
  
  <p>When I use Butter Knife in Android lib, I get the following error:</p>
  
  <pre><code>tutuFragment.java:31: error: attribute value must be constant
      @InjectView(R.id.noContactTV)
  </code></pre>
  
  <p>Has anyone experienced the same issue, and if so, have a solution for it?</p>
