title: Caused by: java.lang.ClassNotFoundException with MaterialList
body: <p>I am getting a <code>Caused by: java.lang.ClassNotFoundException: Didn't find class "com.dexafree.materiallistviewexample.view.MaterialListView"</code>error when running my app.  I am using this library <a href="https://github.com/dexafree/MaterialList" rel="nofollow">https://github.com/dexafree/MaterialList</a>.  Here is my code.  I want to be sure I am not doing something wrong before I post an issue on Github.  Thanks!</p>
  
  <p>Fragment1.java:</p>
  
  <pre><code>public class  FragmentTab1 extends ListFragment {
  
  private Context mContext;
  
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) {
  
      View view = inflater.inflate(R.layout.fragmenttab1, null);
  
      mContext = getActivity();
      MaterialListView mListView = (MaterialListView) view.findViewById(R.id.material_listview);
  
      SimpleCard card = new SmallImageCard(mContext);
      card.setDescription("Description");
      card.setTitle("Title");
      card.setDrawable(R.drawable.ic_launcher);
  
      mListView.add(card);
  
      return view;
  
  }
