This may not be a direct answer but in my case this is how I would do it

First keep track of polyline.

Map<String , Polyline> mHashMap = new HashMap<String , Polyline>();
...
Polyline polyline = this.mMap.addPolyline(new PolylineOptions().....);

mHashMap.put(polyline.getId() , polyline);

Now to remove it

//probably this would happen on `OnActivityResult` of first_activity

Polyline pl = mHashMap.get("polyline_id_from_first_activity_rerouted_from_second_activity");
pl.remove();

Hope it helps :)
