title: Android HelloGoogleMaps to OSMdroid (Open Street Maps)
body: <p>I am trying to reproduce a working HelloGoogleMaps app in Open Street Maps - but I have trouble including the itemized overlay in OSMdroid. </p>
  
  <p>I have looked at several resources but I cannot figure out how to fix the error on OsmItemizedOverlay - I guess I am constructing OsmItemizedOverlay wrongly or have a mixup with OsmItemizedOverlay and ItemizedOverlay? But everything I tried to change just raised more errors...
  "Implicit super constructor ItemizedOverlay() is undefined. Must explicitly invoke another constructor"
  "Cannot make a static reference to the non-static method setMarker(Drawable) from the type OverlayItem" - I hope someone can help me getting the class definition straight?</p>
  
  <p>Thanks so much!</p>
