title: InstaBug, cannot resolve 'Builder'
body: <p>Trying to implement InstaBug first time, however, when I initialize it,</p>
  
  <pre><code> new Instabug.Builder(this, "XXXXXXXXXXXXXXXXXXXX")
              .setInvocationEvent(Instabug.IBGInvocationEvent.IBGInvocationEventShake)
              .build();
  </code></pre>
  
  <p>Android Studio says cannot resolve symbol <code>Builder</code> 
  Though Builder extends from <em>java.lang.Object</em> , helpless to figure why this happens. Any fix?</p>
  
  <p>EDIT:</p>
  
  <pre><code>dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
