How to show infoWindow for Circle on Google Maps in android

view story

http://stackoverflow.com – I want to display circles at specific locations on google maps whose radius will be defined at runtime depending on some value. I could add the circle on map using : Circle circle = map.addCircle(new CircleOptions() .center(result) .radius(Double.parseDouble(size)*100) .strokeColor(Color.RED) .fillColor(Color.BLUE) ); When i click on this circle, i need to display an infoWindow same as the one that appears in case of Markers (i.e setting titles and snippets for each one of them and displaying on clicking it). How to achieve this? (HowTos)
