Hoping that you are aware with android map's Geofencing feature where we can draw/highlight particular area (radius of circle in meter) on Google map as displayed below.
My requirement is that I need to change this area by dragging circle border. Please share your ideas to achieve this. Thanks in advance.
You can achieve this using google maps drawing tools api. Please refer link for the same: https://developers.google.com/maps/documentation/javascript/examples/drawing-tools
