title: Cluster Marker OpenStreetMap java
body: <p>Currently in one project I use  GoogleMaps with ClusterMarker based on PhotSpot  <a href="http://code.google.com/p/android-playground-erdao/wiki/PhotSpot" rel="nofollow">http://code.google.com/p/android-playground-erdao/wiki/PhotSpot</a>.<br>
  I tried to convert it to use OpenStreetMap with mapsforge library( <a href="http://code.google.com/p/mapsforge/" rel="nofollow">http://code.google.com/p/mapsforge/</a>) replacing referenced libraries from googlemaps to mapsforge.<br></p>
  
  <p>I need to override and implement method from mapsforge library in my custom class based on ClusterMarker ( <a href="http://code.google.com/p/android-playground-erdao/source/browse/trunk/SampleClusterMap/src/com/erdao/android/mapviewutil/markerclusterer/ClusterMarker.java" rel="nofollow">http://code.google.com/p/android-playground-erdao/source/browse/trunk/SampleClusterMap/src/com/erdao/android/mapviewutil/markerclusterer/ClusterMarker.java</a> ) from photspot and here I have hit the wall.</p>
  
  <pre><code>@Override
      protected void drawOverlayBitmap(Canvas canvas, Point drawPosition, Projection projection,
              byte drawZoomLevel) {
      }
  </code></pre>
  
  <p>Did any of you tried to create clustermarker overlays on openstreetmap in java or maybe know any open source library that could help?</p>
