title: Android Camera continuous focus
body: <p>I need to implement an app on android which uses the camera and it needs to keep the focus continuously on objects. Whenever user changes the camera position, it should autofocus itself for that position (very much like <em>Google Goggles</em>).</p>
  
  <p>Right now I am using the following code:</p>
  
  <pre><code>    camera.requestautofocus(autofocuscallbak);
  </code></pre>
  
  <p>This works well but it's not continuous...</p>
