case MotionEvent.ACTION_HOVER_MOVE: {
            this.mTimerTaskHover = new TimerTask() {
                public void run() {
                    Runnable docScreenRunnable = new Runnable() {
                        public void run() {
                            playKeyTone();

                        }
                    };

            if (this.mTimerTaskHover != null) {
                this.mTimerTaskHover.cancel();
                this.mTimerTaskHover = null;
                this.mTimerHover.cancel();
                this.mTimerHover.purge();
                this.mTimerHover = null;
                this.mTimerHover = new Timer(); // if timer was cancelled
                                                // starts it again
            }
