According to all the docs I have, such as... this link
"rotation" is a valid marker option. But it's not there!
For instance if you put this code cited in the docs into your program ...
static final LatLng PERTH = new LatLng(-31.90, 115.86);
Marker perth = mMap.addMarker(new MarkerOptions()
.position(PERTH)
.anchor(0.5,0.5)
.rotation(90.0));
the rotation is flagged as not being a valid MarkerOption.
I also tried doing setRotation(float) on a returned Marker object to that got flagged as invalid too.
So, are the docs bad? Am I doing something wrong? How can I rotate the Marker?? Thanks, Gary
