Cannot create route from one point to another ArcGIS Android

Question

i've been trying very hard to create a route between two points(startPoint, endPoint). But i am getting the following error:

Location "Location 1" in "Stops" is unlocated. Location "Location 2" in "Stops" is unlocated. Need at least 2 valid stops. "Stops" does not contain valid input for any route.

Here is my code:

private final String routeTaskURL = "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Route";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mMapView = (MapView) findViewById(R.id.map);
    mMapView.enableWrapAround(true);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                UserCredentials userCredentials = new UserCredentials();
                userCredentials.setUserToken(token, clientID);
                RouteTask routeTask = RouteTask.createOnlineRouteTask(routeTaskURL, userCredentials);
                RouteParameters routeParameters = routeTask.retrieveDefaultRouteTaskParameters();
                NAFeaturesAsFeature naFeatures = new NAFeaturesAsFeature();
                SimpleMarkerSymbol sms = new SimpleMarkerSymbol(
                        Color.RED, 5, SimpleMarkerSymbol.STYLE.CIRCLE);

                Point startPoint = new Point(36.793653, -119.866896);
                Point stopPoint = new Point(36.795488, -119.853345);

                Graphic graphic1 = new Graphic(startPoint, sms);
                Graphic graphic2 = new Graphic(stopPoint, sms);

                StopGraphic startPnt = new StopGraphic(graphic1);
                StopGraphic stopPnt = new StopGraphic(graphic2);

                naFeatures.setFeatures(new Graphic[] {startPnt, stopPnt});
                routeParameters.setStops(naFeatures);

                RouteResult mResults = routeTask.solve(routeParameters);
                System.out.println(mResults.getStops());
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }).start();
}

I've searched the internet. Many developers were/are facing this problem. I've tried all the solutions but none of them worked. I got routeTaskURL from the ArcGIS Routing Sample app. The link which is given in the documentation of ArcGIS maps gives me the 403 error if i open it in the browser.

Note: "token" and "clientID" is declared in the first step and they both are taken from the ArcGIS developers console where i registered my application.

Answer 1

It will work if you switch your X and Y values. See https://stackoverflow.com/a/35139941/720773 for a full description of what is happening.

Answer 2

I don't think you are allowed to use http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Route

In a production app.

Esri has paid options for directions services to use instead.
