Routes won't render to the screen

Hello,

I built a React Native component in Kotlin. I used a SimpleViewManager type of class to expose this component to React Native and I use it to render an esri map. The problem is I cannot use RouteTask properly for creating a route between 2 points on the map and I do not know where the problem is.

This is the function that I use:

private fun findRoute() { val routeTask = RouteTask( context, "https://route-api.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World" ) val routeParametersFuture = routeTask.createDefaultParametersAsync() routeParametersFuture.addDoneListener { try { val routeParameters = routeParametersFuture.get().apply { isReturnDirections = true setStops(routeStops) } // get the route and display it val routeResultFuture = routeTask.solveRouteAsync(routeParameters) routeResultFuture.addDoneListener { val result = routeResultFuture.get() val routes = result.routes if (routes.isNotEmpty()) { val route = routes[0] val shape = route.routeGeometry val routeGraphic = Graphic( shape, SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, Color.BLUE, 2f) ) graphicsOverlay.graphics.add(routeGraphic) } } } catch (e: Exception) { val error = "Error creating default route parameters: " + e.message Toast.makeText(context, error, Toast.LENGTH_LONG).show() Log.e(ArcGISViewMaps::class.simpleName, error) } } }

and I use it in createViewInstance of the SimpleViewManager class that I mentioned before. See below:

override fun createViewInstance(reactContext: ThemedReactContext): MapView { val view = MapView(reactContext) ArcGISRuntimeEnvironment.setApiKey("myAPI") val map = ArcGISMap(BasemapStyle.ARCGIS_STREETS) view.map = map view.setViewpoint(Viewpoint(latitudeDefault, longitudeDefault, 72000.0)) view.graphicsOverlays.add(graphicsOverlay) val pointDisplay1 = Point(longitudeDefault, latitudeDefault, SpatialReferences.getWgs84()) addStop(Stop(pointDisplay1)) val pointDisplay2 = Point(-6.2603,53.37,SpatialReferences.getWgs84()) addStop(Stop(pointDisplay2)) findRoute() return view }

As a context for the RouteTask I use reactContext. I am passing that context from the package manager where I call this class to be exposed to React Native.

Finally, it shows an error that I catch and expose in React Native, the error says:

"Error creating default route parameters: com.esri.arcgisruntime.ArcGISRuntimeException: Invalid call.: Object failed to load, unable to execute task."

If you have any ideas regarding this issue, please do let me know as soon as possible.

Thank you!

Hi,

Does the `reactContext` provides the application or activity context?

Also were you able to perform route task operations outside of React Native setup, like running this tutorial.

Thanks

Not sure if you'll receive this as this is an old post, but I'm having the exact same issue rn. If you have found a solution to this can you please share with me, thanks!
