ArcGIS Runtime SDK for Java - WebMap display issue (spatial reference construction error)

Question

I'm trying to display a map which I created and uploaded on ArcGIS online as a map package:

map = new JMap();
Portal portal = new Portal("http://www.arcgis.com", null);
PortalItem item = null;
item = PortalItem.fetchItem(portal, "9464b884blahblahblah");
WebMap wm = WebMap.newInstance(item);
map.loadWebMap(wm);

I tried the code with a map ID from the samples provided in the docs and it works fine. With the ID of the map I uploaded, however, I get this error:

Java version : 1.8.0_20 (Oracle Corporation) amd64
Rendering engine : DirectX
Unable to construct spatial reference from GCS_WGS_1984

The "Unable to construct spatial reference ..." error message pops up after 1-2 seconds after starting the program, where as the JsonParseException takes about 10 seconds to appear and is triggered by the following line:

 WebMap wm = WebMap.newInstance(item);

I checked the layers I created (in properties, in the coordinate system tab) they do reside under a "GCS_WGS_1984" coordinate system.

Is the JsonParseException somehow linked to the Unable to construct... error message?

Can anybody tell me what am I doing wrong?

Answer 1

Turns out I wasn't exporting with support for ArcGIS Runtime.

I first had to enable this feature: Customize> Sharing> Under the Packaging fieldset> Check "Enable ArcGIS Runtime Tools".

Then I was able to File> Share As> Map Package and check "Support ArcGIS Runtime" and then it worked fine after sharing.
