title: Filtering the camera preview
body: <p>I am trying to display a filtered version of the camera preview.
  The code runs without errors but the device is showing the preview instead of the generated bitmap.   </p>
  
  <p>This is the code for my (very small) Activity: <a href="http://code.google.com/p/ruellia/source/browse/ruellia/src/br/com/ximp/ruellia/RuelliaActivity.java" rel="nofollow noreferrer">http://code.google.com/p/ruellia/source/browse/ruellia/src/br/com/ximp/ruellia/RuelliaActivity.java</a></p>
  
  <p>I suspect the view layering and the surface holder type, but so far no luck... anyone?</p>
