Android after i use map.clear cant add markers

Question

I have a method to a add markers to google map v2 and i wish to clear the markers and then add more markers all while in the map. This is how i add the markers which works fine mapLoc being the map itself. Further down the line i then call mapLoc.clear which gets rid of the markers.

I then wish to add more markers to the map but the markers dont appear when i call this method any help?

        for(int i=0;i<list.size();i++){

           LatLng lg=new LatLng(Float.parseFloat(list.get(i).get(5)), Float.parseFloat(list.get(i).get(6)));

           Marker mark= mapLoc.addMarker(new MarkerOptions().position(lg)
                .title(list.get(i).get(0)).snippet(list.get(i).get(1)).icon(BitmapDescriptorFactory
                          .fromResource(R.drawable.mark2)));
        counter++;
        }

Try to save your `Marker` object in the `HashMap`, and then calling `markers.remove()` instead of `map.clear`, finally use your code above to add `additional markers`.

As we discuss above:
