title: Cluster markers are not clearing in Android
body: <p>I have used cluster concept in my application, i can successfully get the cluster but the problem is not getting updated when the array of markers getting refreshed, right now based on the miles i am refreshing my map </p>
  
  <p>Check it out my below code :</p>
  
  <pre><code>if (map != null) {
  
              map.moveCamera(CameraUpdateFactory.newLatLngZoom(
                      new LatLng(Double.parseDouble(list.get(0).getLatitude()),
                              Double.parseDouble(list.get(0).getLangtitude())),
                      map.getCameraPosition().zoom));
  
              mClusterManager = new ClusterManager&lt;MyItem&gt;(getActivity(), map);
  
              map.setOnCameraChangeListener(mClusterManager);
              map.setOnMarkerClickListener(mClusterManager);
  
          }
          mClusterManager.clearItems();
          for (int i = 0; i &lt; list.size(); i++) {
  
              String title = list.get(i).getName() + "~" + list.get(i).getCity()
                      + "~" + list.get(i).getSector();
  
              MyItem offsetItem = new MyItem(Double.parseDouble(list.get(i)
                      .getLatitude()), Double.parseDouble(list.get(i)
                      .getLangtitude()), title, list.get(i).getSector(),
                      String.valueOf(i));
  
              mClusterManager.addItem(offsetItem);
          }
          mClusterManager.cluster();
  </code></pre>
  
  <p>Instead of updating markers are added for each refreshment, <code>mClusterManager.clearItems();</code> its not working, dont know what mistake i have done, please figure out
  Thanks in Advance</p>
