// Ensure that the camera resolution is a multiple of 8, as the screen may not be.
// TODO: A better solution would be to request the supported preview resolutions
// and pick the best match, but this parameter is not standardized in Cupcake.
Point cameraResolution = new Point();
cameraResolution.x = ( screenResolution.x >> 3 ) << 3;
cameraResolution.y = ( screenResolution.y >> 3 ) << 3;
parameters.setPreviewSize( cameraResolution.x, cameraResolution.y );
