I need to add a list of geopoints as markers on top of my custom OSM map in my android device, the below code is a sample for showing up one marker.
GeoPoint startPoint = new GeoPoint(48.13, -1.63);
Marker startMarker = new Marker(map);
startMarker.setPosition(startPoint);
startMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
map.getOverlays().add(startMarker);
