title: Android DataBinding Custom Binding Adapter Warning
body: <p>I followed the data binding documentation for <strong>Custom Binding Adapter</strong> for <strong>image loading</strong> from official Android Developers site:
  <a href="http://developer.android.com/tools/data-binding/guide.html">http://developer.android.com/tools/data-binding/guide.html</a></p>
  
  <p>After successfully compiling the code I get a warning which is:</p>
  
  <pre><code>Warning:Application namespace for attribute bind:imageUrl will be ignored.
  </code></pre>
  
  <p>My Code is as follow:</p>
  
  <pre><code>@BindingAdapter({"bind:imageUrl"})
      public static void loadImage(final ImageView imageView, String url) {
          imageView.setImageResource(R.drawable.ic_launcher);
          AppController.getUniversalImageLoaderInstance().displayImage(url, imageView);
      }
  </code></pre>
  
  <p><strong>Why this warning is generated?</strong></p>
