        class VideoEngine extends Engine

                        mediaPlayer.setSurface(holder.getSurface());
                        mediaPlayer.start();
                    }

                @Override

                    {
                        Log.i( TAG, \"( INativeWallpaperEngine ): onSurfaceDestroyed\" );
                        playheadTime = mediaPlayer.getCurrentPosition();
                        mediaPlayer.reset();
                        mediaPlayer.release();
                    }
        }
