How to supply account info when building offline map

EricDUCOS1

Hi,

This part of code is what I have written based on the "Create an offline map" Guide:

            Map theMap = new Map(new Uri(_configService.ServerConfiguration.SigMapUrl));
            OfflineMapTask task = await OfflineMapTask.CreateAsync(theMap);
           
            Envelope areaOfInterest = theMap.Item.Extent;
            GenerateOfflineMapParameters parameters = await task.CreateDefaultGenerateOfflineMapParametersAsync(areaOfInterest);
            parameters.MaxScale = 3000;

            OfflineMapCapabilities results1 = await task.GetOfflineMapCapabilitiesAsync(parameters);

            DependencyService.Get<IFileService>().CreateLocalDBFolder(App.CurrentConfigName);
            string pathToOutputPackage = DependencyService.Get<IFileService>().CreateLocalDBFolder(App.CurrentConfigName+"/Sig");
            DependencyService.Get<IFileService>().EmptyFolder(pathToOutputPackage);

            GenerateOfflineMapJob job = task.GenerateOfflineMap(parameters, pathToOutputPackage);
            GenerateOfflineMapResult results2 = await job.GetResultAsync();

When I run this part of code, a dialog opens in middle of the process that asks to me to give login and password to get acces to tiled basemap.

What sort of code should I add to avoid this dialog opening and to give these information (login and password)  hard-coded in code ?

And I have a second question, concerning this part of code. Downloading the tiles from the server can be a long operation. Is there some ways to have a sort of progress event to give some UI progress on interface (% of downloading for exemple) ?

Regards.

Hi Eric,

Suppose, you are trying to access the tile layer, "https://tiledbasemaps.arcgis.com/arcgis/rest/services/World_Street_Map/MapServer"
and it will  ask the AGOL credential to access. You could access the layer using AuthenticationManager and hardcode the credentials as below:

using Esri.ArcGISRuntime.Security;

string ONLINE_BASEMAP_URL = "https://tiledbasemaps.arcgis.com/arcgis/rest/services/World_Street_Map/MapServer";
string ONLINE_BASEMAP_TOKEN_URL = "https://www.arcgis.com/sharing/rest/generatetoken";

ArcGISTiledLayer tiledLayer = new ArcGISTiledLayer(new Uri(ONLINE_BASEMAP_URL));
AuthenticationManager auth = AuthenticationManager.Current;
var cred = await auth.GenerateCredentialAsync(new Uri(ONLINE_BASEMAP_TOKEN_URL), <AGOL_USERNAME>, <AGOL_PASSWORD>);

tiledLayer.Credential = cred;

Hope that helps.
