title: Here SDK Android Zoom to several markers
body: <p>Im currently testing out Here Maps SDK for Android. I have a set of markers and i need to be able to zoom in so they all fit the screen. I currently tried using GeoBoundingBox but you have to insert 2 places at once (the corners). Searched the documentation but didnt find any relevant information. <strong>Is it possible and how can I do it?</strong></p>
  
  <p><strong>How I tried to do it</strong></p>
  
  <pre><code> GeoBoundingBox geoBoundingBox = hereMap.getBoundingBox();
      if (data != null &amp;&amp; data.getItemGroups() != null) {
          for (ItemGroup itemGroup: data.getItemsGroups()) {
              ClusterLayer clusterLayer = new ClusterLayer();
              for (Item item : itemGroup.getItems()) {
                  if (item != null &amp;&amp; item.isLatLngOk()) {
                      GeoCoordinate coordinate = new GeoCoordinate(item .getLat(), item .getLng());
                      clusterLayer.addMarker(new MapMarker(coordinate, image));
                      geoBoundingBox.merge(new GeoBoundingBox(coordinate, coordinate));
                  }
              }
              hereMap.addClusterLayer(clusterLayer);
              hereMap.zoomTo(geoBoundingBox, Map.Animation.LINEAR, 0); // This does not work
          }
      }
