Dragging markers in google map Android

I have a small problem in my application where I'm able to drag marker to any position on the visible map.I referred to this answer on stackoverflow where I can animate the map on marker drag.but even if I don't drop the marker on map it gets dropped by itself.

here's my code to make it more clear

    @Override
        public void onMarkerDrag(final Marker marker) 
        {
            final View view = getFragmentManager().findFragmentById(R.id.map).getView();
            if(view.getViewTreeObserver().isAlive())
            {
                view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener()
                {

                    @Override
                    public void onGlobalLayout() 
                    {
                        view.getViewTreeObserver().removeGlobalOnLayoutListener(this);

                        mGoogleMap.animateCamera(CameraUpdateFactory.newCameraPosition(new CameraPosition.Builder()
                        .target(marker.getPosition()).zoom(13).build()));

                    }
                });
            }


        }
    };

try below code for drag marker:-

    map. addMarker(new MarkerOptions().position(new LatLng(lat, lng)).draggable(true));

and below method for get lat nd lng :-

    map.setOnMarkerDragListener(new OnMarkerDragListener() 
    {
        @Override
        public void onMarkerDragStart(Marker marker) 
        {
            // TODO Auto-generated method stub
        }

        @Override
        public void onMarkerDragEnd(Marker marker) 
        {
            // TODO Auto-generated method stub
            lat     = marker.getPosition().latitude;
            lng     = marker.getPosition().longitude;
        }

        @Override
        public void onMarkerDrag(Marker marker)
        {
            // TODO Auto-generated method stub
        }
     });
