How to make PorterDuffXfermode on camera image in SurfaceView?

Question

Android

I want to do like this:

Canvas canvas = new Canvas(drawingBitmap);
Paint paint = new Paint();
canvas.drawBitmap(sourceBitmap, 0, 0, paint);
paint.setXfermode(new PorterDuffXfermode (android.graphics.PorterDuff.Mode.SCREEN)); // способ смешивания
canvas.drawBitmap(destinationBitmap, 0, 0, paint);

The effect is the same as in the Retrika application, applying the effect to the camera.
