    • GLMapMarkerLayer

      public GLMapMarkerLayer​(@Nullable java.lang.Object[] markers, GLMapMarkerStyleCollection styleCollection, double clusteringRadius, int drawOrder)
      Initializes GLMapMarkerLayer with given markers and `styleCollection`
      Parameters:
      markers - Array of marker objects. Usually you set objects with data, that you need to display on map.
      styleCollection - A style collection object used to display markers.
      drawOrder - Draw order used to sort objects on map
      clusteringRadius - Radius of clustering in points. If 0 marker clustering will be disabled
