Camera zoom not working

Question

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?

camera = Came

if you want to used seekbar to change camera preview zoom in-out used following code its perfectly running :

    seekbarZoom = (SeekBar) findViewById(R.id.seekBarZoom);
    seekbarZoom.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
            // TODO Auto-generated method stub
            Log.d(TAG, "progress:"+progress);

            if(mCamera.getParameters().isZoomSupported()){

                Parameters params = mCamera.getParameters();
                params.setZoom(progress);
                mCamera.setParameters(params);
            }
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub
            Log.d(TAG, "onStartTrackingTouch");
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub
            Log.d(TAG, "onStartTrackingTouch");
        }

    });
