title: Camera zoom not working
body: <p>I am using the API 2.1 and my debug shows a max zoom value of 15. The code here does not make the camera zoom. How do I get the camera to zoom?</p>
  
  <pre><code>camera = Camera.open();
  Camera.Parameters parameters = camera.getParameters();
  parameters.set("orientation", "portrait");
  parameters.setWhiteBalance(Camera.Parameters.WHITE_BALANCE_TWILIGHT);
  int zoom = parameters.getMaxZoom();
  Log.d(TAG, "Zoom " + zoom);
  parameters.setZoom(15);
  camera.setParameters(parameters);
  </code></pre>
