World route service for Android not returning results

Hi,
Iam using the arcGIS Android SDK v10.1.1. I want to plot the route between 2 points in the European region. Iam using the World Route service (as per http://blogs.esri.com/esri/arcgis/2013/04/08/legacy-geocoding-and-routing-services-at-httptasks-arcgisonline-com-will-be-retired-on-december-31-2013/) to get route info. But the server does not respond (nor times out) when solve is called.
Following is a snippet:

RoutingParameters routeParams = new RoutingParameters();
routeParams.setImpedanceAttributeName("Length");
String routeTaskURL = "https://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World";

//Prepare user credentials
UserCredentials userCredentials = new UserCredentials();
userCredentials.setAuthenticationType(AuthenticationType.TOKEN);
userCredentials.setSSLRequired(false);
userCredentials.setUserAccount(<userName>, <psswd>);
userCredentials.setUserToken(<user_token>, <referer>);

RoutingTask routeTask = new RoutingTask(routeTaskURL, userCredentials);

Point point1 = (Point) GeometryEngine.project(p1, mOutSpacialRef, mMap.getSpatialReference());//Spatial reference 4326
StopGraphic startPnt = new StopGraphic(point1);

Point point2 = (Point) GeometryEngine.project(p2, mOutSpacialRef, mMap.getSpatialReference());
StopGraphic endPnt = new StopGraphic(point2);

naFeatures.setFeatures(new Graphic[] { startPnt, endPnt });

NAFeaturesAsFeature naFeatures = new NAFeaturesAsFeature();
naFeatures.setSpatialReference(mMap.getSpatialReference());
naFeatures.setCompressedRequest(true);
routeParams.setStops(naFeatures);
routeParams.setOutSpatialReference(mOutSpacialRef);
try
{
mResults = routeTask.solve(routeParams);//hangs here. no response and no timeout
} catch (Exception e)
{
e.printStackTrace();
return null;
}

The app hangs after calling solve, meaning there's no response from the server and hence waits forever. Can anyone please point out the mistake?

Thanks,

Found the issue.
1. The account to be used to create application and generare token must be created from http://www.esri.com/software/arcgis/arcgisonline/evaluate. Click on "Create a NEW Esri Account" button.
2. The outspatialreference to be set to 102100 everywhere. Following is the modification required.
   // Create the stop points from point geometry
   StopGraphic startPnt = new StopGraphic(GeometryEngine.project(startPoint, SpatialReference.create(4326), SpatialReference.create(102100)));
   StopGraphic endPnt = new StopGraphic(GeometryEngine.project(endPoint, SpatialReference.create(4326), SpatialReference.create(102100)));

   // set features on routing feature class
   naFeatures.setFeatures(new Graphic[] { startPnt, endPnt });
   naFeatures.setSpatialReference(SpatialReference.create(102100));
                        routeParams.setOutSpatialReference(SpatialReference.create(102100));

Thanks,
