I had the same problem.
i solved it by changing the following:
in HelloGoogleMaps,java:
HelloItemizedOverlay itemizedoverlay = new
HelloItemizedOverlay(drawable);
replace by:
HelloItemizedOverlay itemizedoverlay = new
HelloItemizedOverlay(drawable, this);
and in HelloItemizedOverlay.java change the new constructor with the
boundCenterBottom method to see the marker:
public HelloItemizedOverlay(Drawable defaultMarker, Context
context)
{
super(boundCenterBottom(defaultMarker));
mContext = context;
}
