Loading MapView from WebMap loaded by webmap.json

ValerioSavino · ‎11-27-2015

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:
