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
import QtQuick 2.7
import QtQuick.Controls 2.1
import QtQuick.Controls.Material 2.1
import QtQuick.XmlListModel 2.0
import ArcGIS.AppFramework 1.0
import Esri.ArcGISRuntime 100.2

//! [GOSymbols MapView]

// the center of the mapview

}
//! [GOSymbol line symbol]
// add all the graphics to the graphics overlay
Component.onCompleted: {
// add boat route
graphicsOverlay.graphics.append(createGraphic(createBoundaryRoute(), fillSymbol));
// add the nesting ground

// create and return a graphic
function createGraphic(geometry, symbol) {
var graphic = ArcGISRuntimeEnvironment.createObject("Graphic");
graphic.geometry = geometry;
graphic.symbol = symbol;
return graphic;
}
//! [GOSymbol createGraphic]
//! [GOSymbol createBoatRoute]
// create the boat route
function createBoundaryRoute() {
// create polygine using json
return ArcGISRuntimeEnvironment.createObject("Polygon", {"json": boundaryJson});
}

property var boundaryJson : {"paths":[[[172.49307355493, -43.4810759934974],

}
Solved! Go to Solution.
Everything in ArcGIS Runtime that can go to/from JSON is based on the ArcGIS REST spec.
So for geometries, you can reference this doc - Geometry objects—Common Data Types | ArcGIS for Developers
For symbols, Symbol Objects—Common Data Types | ArcGIS for Developers
I am going to tag ArcGIS Runtime SDK for Qt to see if anyone in that group knows the json format to create Polygon.
I think this must be related to how the json is supposed to be formatted.

Thanks i was using paths in attributes instead of rings
