There a known limitation in that the ViewshedFunction only works with projected coordinate systems.  Passing in a WGS84 based ContinuousField will not work and this will be reported in the AnalysisViewState.  There is however a workaround where you can project your WGS84 data into the coordinate system of your MapView.  Take a look at the ContinuousField.CreateAsync method. When you display the viewshed results in a FieldAnalysis, you need to have created the results in the same spatial reference as your MapView. We are working on functionality for projecting field data on the GPU for a future release. Let me know if that helps.   ... View more

@NancySuez  Assuming you are writing a desktop JavaFX application (not a JavaScript web app), take a look at this sample application which listens to a setOnMouseClicked event and converts the screen coordinates to a WGS84 (lat / long) point.   Key steps are: // click event to display the callout mapView.setOnMouseClicked(e -> { // check that the primary mouse button was clicked and user is not panning if (e.getButton() == MouseButton.PRIMARY && e.isStillSincePress()) { // create a point from where the user clicked Point2D point = new Point2D(e.getX(), e.getY()); // create a map point from a point Point mapPoint = mapView.screenToLocation(point); // project user-tapped map point location Point projectedPoint = (Point)GeometryEngine.project(mapPoint, SpatialReferences.getWgs84());    Does this help? ...

@padmalcom  What you are trying to do here isn't possible I'm afraid; not in the Maps SDK alone. The offline map tasks which generates a mobile map package is for use with a web map which is published in ArcGIS Online or your own Enterprise environment.  The creation of the mobile map package is a server side operation and there is no logic in the Maps SDK to perform this operation. The solution here might be to publish your vector tile data into a webmap and you can use that to request a smaller area using the offline workflows.   I should also make you aware that the Maps SDK for Java is being deprecated this year so you may want to consider using one of the other Native Maps SDKs for a new project.

I've added some code below which shows you how to check the cause of an error when loading a Portal or a PortalItem Portal portal = new Portal("https://www.arcgis.com/"); System.out.println("loading portal"); portal.loadAsync(); portal.addDoneLoadingListener(()-> { //check status of portal loading System.out.println("Portal load status " + portal.getLoadStatus()); if (portal.getLoadStatus() == LoadStatus.LOADED) { // portal loaded okay so let's try the portal item PortalItem portalItem = new PortalItem(portal, "92ad152b9da94dee89b9e387dfe21acd"); portalItem.loadAsync(); portalItem.addDoneLoadingListener(()-> { // check portal item load status System.out.println("portal item load status " + portalItem.getLoadStatus()); if (portalItem.getLoadStatus() == LoadStatus.LOADED) { // make map from portal item and add to mapview it displays ArcGISMap map = new ArcGISMap(portalItem); mapView = new MapView(); mapView.setMap(map); // add the map view to the stack pane stackPane.getChildren().addAll(mapView); } else { System.out.println("portal item failed to load"); System.out.println(portalItem.getLoadError().getCause()); } }); } else { System.out.println("portal failed to load"); System.out.println(portal.getLoadError().getCause()); } });   I'm not sure why you are specifically getting the error above, but you might get some clues from the code above. I would also not use Java 19, this isn't an LTS release and isn't supported.  Ideally you should be using Java 21. You should also read this blog post which says that we are about to deprecate the Java SDK, so you should consider an alternative technology for new projects. Does this help? ... View more
