Google maps V2

// HUE is a float value ranged between 0 and 360
BitmapDescriptor defaultMarker = BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE);

// Alternatively you could create if with any bitmap desired
     
mMap.addMarker(
 new MarkerOptions()
  .position(data.getLatLong())
  .draggable(false)
  .visible(true)
  .icon(defaultMarker)
  .title("Some title"));

1) If you have a the map fragment inside an activity:
((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

2) If you have a map fragment inside a fragment:
((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMap();
