Loading MapView from WebMap loaded by webmap.json

ValerioSavino — Fri, 27 Nov 2015 13:50:12 GMT

Hello,

I tried to load a MapView using a WebMap. The WebMap is loaded from a json downloaded by Collector. This is my code:

First, I load the JsonParser that load the webmap.json

JsonFactory factory = new JsonFactory();

JsonParser parser = factory.createJsonParser(new FileInputStream(Constants.JSON_WEBMAP_PATH));

then I get an Evelop (called "extent") and a SpatialReference (called "sp").

Whit this values, load the webmap

webMap = WebMap.newInstance(parser, extent, sp);

and then, load the map

map = new MapView(MyActivity.this, webMap, null, null);

After this, I got this two errors:

11-27 13:00:12.460 5388-5678/com.esri.android.test.esrimasktest E/ArcGIS: Failed to check the service owning system URL

Any ideas to resolve? Thanks to all!

To load a MapView from a webmap, use one of the constructors on MapView which takes a URL to the webmap:
