I want to populate map from json data in Android, but can't find any relevant information/method to do so. Does anyone over there have any idea ?

shailendrarajawat — Fri, 06 Feb 2015 06:25:53 GMT

the format of json is

{

"currentVersion": 10.01,

"serviceDescription": "",

"mapName": "Layers",

"description": "",

"copyrightText": "",

"layers": [

{

"id": 0,

"name": "",

"parentLayerId": -1,

"defaultVisibility": true,

"subLayerIds": null,

"minScale": 0000,

"maxScale": 0

}

"tables": [],

"spatialReference": {},

"singleFusedMapCache": false,

"initialExtent": {

"xmin": ,

"ymin": ,

"xmax": ,

"ymax": ,

"spatialReference": {}

"fullExtent": {

"xmin": -1.0547305

}

I know we can create layer using ArcGISDynamicMapServiceLayer(url) constructor, but i have json instead of URL.

iOS sdk provides this facility

AGSDynamicMapServiceLayer *dynamicLayer = [[AGSDynamicMapServiceLayer alloc] initWithJSON:mapJson];

so i believe it should be possible for android as well. But have no idea.. how

Hi Shailendra,

I'm afraid right now we don't have a similar method in Android to do so. Initialization parses Json from REST end point.

We're showing data from a JSON web service on our map. We grab the json from our web service. Take that and reformat it into the json format used by arcgis server (documented here - ArcGIS Server REST API ). Take the resulting json, feed it into FeatureSet.fromJson(JsonParser) to get a featureset and add that to a graphicslayer.

It's not simple/pretty, but it does the job.
