i'm trying to try out the drive area feature, and i am getting null features back. I'm using code from the sample on this: code snippet: // default value double breakValue1 = 2.0, breakValue2 = 5.0, breakValue3 = 10.0; ServiceAreaParameters sap = new ServiceAreaParameters(); NAFeaturesAsFeature nfaf = new NAFeaturesAsFeature(); // Convert point to EGS (decimal degrees) Point p = (Point) GeometryEngine .project(startLocation, wm, egs); nfaf.addFeature(new Graphic(p, null)); sap.setFacilities(nfaf); // Set the service area output SR to our map service's SR sap.setOutSpatialReference(wm); // Set the default break values with our entered values sap.setImpedanceAttributeName("TravelTime"); sap.setDefaultBreaks(new Double[]{breakValue1, breakValue2, breakValue3}); // Create a new service area task pointing to an NAService // (null credentials -> free service) ServiceAreaTask sat = new ServiceAreaTask(mDriveAreaServiceURL, mCredentials); // Solve the service area and retrieve the result. ServiceAreaResult saResult = sat.solve(sap); return saResult;
