You can use an offline network to enable routing in disconnected scenarios. For example, you could provide offline location capabilities to field workers repairing critical infrastructure in a disaster when network availability is limited.
How to use the sample
Tap near a road to start adding a stop to the route, tap again to place it on the map. A number graphic will show its order in the route. After adding at least 2 stops, a route will display. Choose "Fastest" or "Shortest" to control how the route is optimized. The route will update on-the-fly while moving stops. The green box marks the boundary of the routable area provided by the offline data. This sample limits routes to 5 stops for performance reasons.
How it works
Create the map's Basemap from a local tile package using a TileCache and ArcGISTiledLayer
Create a RouteTask with an offline locator geodatabase.
Get the RouteParameters using routeTask.CreateDefaultParameters()
Create Stops and add them to the route task's parameters.
Solve the Route using routeTask.SolveRouteAsync(routeParameters)
Create a graphic with the route's geometry and a SimpleLineSymbol and display it on another GraphicsOverlay.
Offline data
The data used by this sample is available on ArcGIS Online.
About the data
This sample uses a pre-packaged sample dataset consisting of a geodatabase with a San Diego road network and a tile package with a streets basemap.
