Info Window not opened

[ostermannBernd]

Calling showInfoWindow() of class DelegatingMarker
sometimes the InfoWindow was not opened, but clicking the marker opens the Info Window.
The error was caused by the lines:
In onShowInfoWindow of class GridClusteringStrategy:
if (cluster.getMarkersInternal().size()< mMinMarkersCount){
or in older version:
if (cluster.getMarkersInternal().size() ==1){

and in refresh() of class ClusterMarker:
else if (count <mStrategy.getMinMarkersCount())

In my implementation mMinMarkersCount was set to 5 and mStrategy.getMinMarkersCount() results to 5.
cluster.getMarkersInternal().size() sometimes was 5 and count too.
Replacing the affected lines by:
if (cluster.getMarkersInternal().size()<= mMinMarkersCount){ else if (count <=mStrategy.getMinMarkersCount())

resolves this issue.
