Access a web map that is secured with ArcGIS token-based authentication.
Use case
Allows you to access a secure service with the convenience and security of ArcGIS token-based authentication. For example, rather than providing a user name and password every time you want to access a secure service, you only provide those credentials initially to obtain a token which can then be used to access secured resources.
How to use the sample
Once you launch the app, you will be challenged for an ArcGIS Online login to view the protected map service. Enter a user name and password for an ArcGIS Online named user account (such as your ArcGIS for Developers account). If you authenticate successfully, the protected map service will display in the map.
How it works
Create an AuthenticationChallengeHandler using the DefaultAuthenticationChallengeHandler to handle the challenges sent by the protected map service.
Set the AuthenticationChallengeHandler used by the AuthenticationManager.
Create a Portal.
Create a PortalItem for the protected web map using the Portal and Item ID of the protected map service.
Create a map to display in the MapView using the PortalItem.
Set the map to display in the MapView.

About the data
The Traffic web map uses public layers as well as the world traffic (premium content) layer. The world traffic service presents historical and near real-time traffic information for different regions in the world. The data is updated every 5 minutes. This map service requires an ArcGIS Online organizational subscription.
