Camera crashes in Android 2.2

Question

I have tested my application on the Android SDK on everything from 1.5 to 2.2 and the camera code in my activity works fine. Running it on a device with 2.1 is also working. But the same app does not work with 2.2 on HTC Desire and Nexus One and the app crashes. Any ideas why they might be happening?

Am using import android.hardware.Camera;.

Inside onCreate I have this:

preview = (SurfaceView) findViewById(R.id.preview);
        previewHolder = preview.getHolder();
        previewHolder.addCallback(surfaceCallback);
        previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

And the callback is

SurfaceHolder.Callback surfaceCallback = new SurfaceHolder.Callback() {

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        camera.stopPreview();
        camera.release();
        camera = null;
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        camera = Camera.open();
        try {
            camera.setPreviewDisplay(previewHolder);
        } catch (Throwable t) {
            Log.e(TAG, "Exception in setPreviewDisplay", t);
            Toast.makeText(CameraActivity.this, t.getMessage(),
                    Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width,
            int height) {
        Camera.Parameters parameters = camera.getParameters();
        parameters.setPreviewSize(width, height);
        camera.setParameters(parameters);
        camera.startPreview();
    }
};

Need to set the preview size of the camera after getting the optimal camera sizes. Here are the details and the code for the fix-
