How to draw an overlay on a SurfaceView used by Camera on Android?

Solution 1: I have a simple program that draws the preview of the Camera into a SurfaceView . What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView , in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw). This is a simplify version of the SurfaceView subclass I have: public class Superficie extends SurfaceView implements SurfaceHolder . Callback { SurfaceHolder mHolder ; public Camera camera ; Superficie ( Context context ) { super ( context ); mHolder = getHolder (); mHolder . addCallback ( this ); mHolder . setType ( SurfaceHolder . SURFACE_TYPE_PUSH_BUFFERS ); } public void surfaceCreated ( final SurfaceHolder holder ) { camera = Camera . open (); try {
