I think it is better to use AsyncTasks in this case:

/**
     * Async task to get the road in a separate thread. 
     */
    private class UpdateRoadTask extends AsyncTask {

        protected Road doInBackground(Object... params) {
            @SuppressWarnings("unchecked")
            ArrayList waypoints = (ArrayList)params[0];
            RoadManager roadManager = new OSRMRoadManager();


            return roadManager.getRoad(waypoints);
                                                        }
         @Override
        protected void onPostExecute(Road result) {
            road = result;
             // showing distance and duration of the road 
            Toast.makeText(getActivity(), "distance="+road.mLength, Toast.LENGTH_LONG).show();
            Toast.makeText(getActivity(), "durée="+road.mDuration, Toast.LENGTH_LONG).show(); 

            if(road.mStatus != Road.STATUS_OK)
            Toast.makeText(getActivity(), "Error when loading the road - status="+road.mStatus, Toast.LENGTH_SHORT).show();
            Polyline roadOverlay = RoadManager.buildRoadOverlay(road,getActivity());

            map.getOverlays().add(roadOverlay);
            map.invalidate();
            //updateUIWithRoad(result);
                                                    }
    }

then call it new UpdateRoadTask().execute(waypoints);
