Follow the steps outlined in the Android Developer reference pages. There's no requirement to have a 'shutter button'. You can create a dummy SurfaceHolder if you don't want to show the image on the screen, e.g.

SurfaceView surface = new SurfaceView(context);
cam.setPreviewDisplay(surface.getHolder());
