Hi i m naive to arcgis appstudio and trying to create multiple polygons through JSON set of vertices, i have my vetices in json format in db like below, but my geometry symbol do not support it.
Kindly guide in right direction.
Or my question could be like.. how to create a polygon through JSON data
