title: obj file in Rajawali library
body: <p>I had tried rajawalivuforia. I want to add an obj file to render on my marker.
  Here is my code:</p>
  
  <pre><code>LoaderOBJ objParser = new LoaderOBJ(mContext.getResources(), mTextureManager, R.raw.apple_obj);
          objParser.parse();
          mApple = objParser.getParsedObject();
          addChild(mApple);
  </code></pre>
  
  <p>The app crashed after I added in this code. Is there any wrong with this code?
  Please help!
  Thanks.</p>
