title: Android setImageUri not working with asset Uri
body: <p>I am using the following code to set an image from the assets folder.</p>
  
  <pre><code>Uri numBgUri = Uri.parse("file:///android_asset/background_numbers.png");
  numBgImage.setImageURI(numBgUri);
  </code></pre>
  
  <p>The background_numbers.png file definitely exists in the assets root directory.  I am getting a FileNotFoundException in the log: -</p>
  
  <pre><code>09-23 17:05:23.803: WARN/ImageView(23713): Unable to open content: file:///android_asset/background_numbers.png
  </code></pre>
  
  <p>Any ideas what I could be doing wrong?</p>
  
  <p>Thanks!</p>
