Migrate to ArcGIS location services

Follow these steps to migrate your existing ArcGIS Runtime app to use ArcGIS location services.

This information is intended for developers who have an existing app built with one of the ArcGIS Runtime APIs and would like to update it to use ArcGIS location services. To use the services, your app must use ArcGIS Runtime version 100.10 or later. Use the current version of ArcGIS Runtime to ensure that you have access to the latest capabilities.

If your app was built with ArcGIS Runtime version 10.x, refer to the Migrate to 100.x from 10.2.x topic for help migrating to 100.x.

Authentication

To use any of the ArcGIS location services, your app must provide authentication with an access token. Access tokens define the scope and permissions available to your application.

There are three kinds of access tokens:

  • API key: a permanent token that grants your application access to ready-to-use services.
  • ArcGIS identity: a temporary token generated with OAuth 2.0 that gives your application access to the private content and ready-to-use services available to an existing ArcGIS user's account.
  • Application credentials: a temporary token generated with OAuth 2.0 that authorizes access to ready-to-use services.

Learn more about getting and using an access token in Security and authentication and the Display a map tutorial.

Global API key

You can provide your API key to ArcGIS Runtime when your app starts by setting it on ArcGISRuntimeEnvironment.

    public partial class App : Application
    {

        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            // Note: it is not best practice to store API keys in source code.
            // The API key is referenced here for the convenience of this tutorial.
            Esri.ArcGISRuntime.ArcGISRuntimeEnvironment.ApiKey = "YOUR_API_KEY";
        }

    }
}

This sets a global API key that will be used to access all ArcGIS location services used by your app. If needed, you can override this key by explicitly setting a different key on layers, basemaps, or any other classes that use platform location services (those that implement the APIKeyResource interface).

Basemaps

Review the basemap layer service and the variety of basemaps available. Create a new basemap using one of the enumeration values from BasemapStyle and use it to create your Map.

You can set an API key directly on the basemap or default to a global API key if one is set for the app.

// Create a new 'topographic' basemap.
var basemap = new Basemap(BasemapStyle.ArcGISTopographic);

// Optionally, set a specific API key for the basemap.
// (Not required if a global API key is set)

basemap.ApiKey = "YOUR_API_KEY";

// Create a new map that uses the basemap.
var map = new Map(basemap);

Geocoding

Use the geocoding service and provide an API key, either globally for the app, or by setting it explicitly on your LocatorTask.

Routes and directions

Access to routing and directions APIs is unchanged with the new ArcGIS location services introduced with ArcGIS Platform. While authentication has always been required to access these services, you now have the ability to use these services with an API key in addition to ArcGIS identity.

See the Find routes and directions topic for more information.
