title: Rendering Problems: Class could not be instantiated: - android.support.v4.widget.DrawerLayout
body: <p>I am newbie and trying to develop android app.
  I used following tutorial and everything is good (i.e. no error/red icon).
  <a href="http://developer.android.com/training/implementing-navigation/nav-drawer.html" rel="nofollow">http://developer.android.com/training/implementing-navigation/nav-drawer.html</a></p>
  
  <p>However, on activity xml file I am getting following error:
  The following classes could not be instantiated:
  - android.support.v4.widget.DrawerLayout (Open Class, Show Exception)</p>
  
  <p>I have searched google and stack overflow. Found similar issue, However no one answered for those. Assuming if someone faced same problem and managed to resolve. </p>
  
  <p>Note: I am using Android-Studio.</p>
  
  <p>Activty.xml have following flow:</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/drawer_layout" ...........
  tools:context=".MyActivity"&gt;
  
      &lt;FrameLayout
          android:id="@+id/content_frame"........
          android:layout_alignParentEnd="true"&gt;
  
          &lt;EditText
              android:layout_width="match_parent"
              android:layout_height="match_parent"/&gt;
      &lt;/FrameLayout&gt;
  
      &lt;ListView android:id="@+id/left_drawer"
          android:layout_width="240dp"........
          android:background="#111"/&gt;
  
      &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
