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!
