title: camera parameters can not be set
body: <p>I do not know why logact generates error when i set the camera parameters regarding <code>setSceneMode</code> and <code>setColorEffect</code> as show below, and says <code>set parameters failed</code>
  but when I set the aforementioned methods to <code>SCENE_MODE_CANDLELIGHT</code>and <code>EFFECT_SOLARIZE</code> respectively it works</p>
  
  <p>JavaCode:</p>
  
  <pre><code>@Override
  public void surfaceChanged(SurfaceHolder holder, int format, int width,int height) {
      // TODO Auto-generated method stub
      android.hardware.Camera.Parameters camParameter = this.myCamera.getParameters();
      camParameter.setSceneMode(Parameters.SCENE_MODE_BEACH);
      camParameter.setColorEffect(Parameters.EFFECT_WHITEBOARD);
      camParameter.setFlashMode(Parameters.FLASH_MODE_AUTO);
      camParameter.setPreviewSize(width/2, height/2);
      camParameter.setPictureSize(width/2, height/2);
      myCamera.setParameters(camParameter);
      myCamera.startPreview();
  }
  </code></pre>
