Hello,  We are downloading offline feature layers for use in our application.  Following the "best practices" in the example here: https://developers.arcgis.com/net/android/api-reference/html/T_Esri_ArcGISRuntime_Tasks_Offline_GeodatabaseSyncTask.htm I am calling UnregisterGeodatabaseAsync following successful creation of the offline download.  However, this call throws an error "Unable to complete operation."  The details in the exception are "Cannot access the replica". Why would the server not be able to access the replica?  Did it create one? How can I find out what is going on?   GenerateGeodatabaseJob job = gdbSyncTask.GenerateGeodatabase(generateGdbParams, nativeOfflinePath); Geodatabase geodatabase = null; try { await job.GetResultAsync(); geodatabase = job.GetResultAsync().Result; } finally { if (job.Status == JobStatus.Succeeded && geodatabase != null) { try { await gdbSyncTask.UnregisterGeodatabaseAsync(geodatabase); } catch (Exception ex) {   // WHAT? } } }   ...

https://developers.arcgis.com/documentation/security-and-authentication/api-keys/ We are interested in using API Keys as one mode of security authentication for our application, when users do not require user-specific access.  At the site above, it says "Only ArcGIS Developer accounts can use API keys to read private content. ArcGIS Organization users should use OAuth 2.0 to obtain ArcGIS identity credentials to read private user content and access services on a user's behalf." Does this mean that this functionality is not recommended for our users?   Also: "During the beta period, accessing private content with an API key is free. A pricing model will be announced in Q2 of 2020." Was there a pricing model announced for use of API keys?     ... View more

I'm trying to learn how to consume an "Annotation Layer" from the UWP Runtime.  My first thought was to use the AnnotationLayer object in the same way that I had used "FeatureLayer" before.   Uri uri = new Uri(_AnnotationUri.ToString() + "/" + _AnnotationLayerId.ToString()); _AnnotationLayer = new AnnotationLayer(uri); _AnnotationLayer.IsVisible = true; _MapView.Map.OperationalLayers.Add(_AnnotationLayer); await _AnnotationLayer.LoadAsync(); However, this gives an error "invalid response" on the last line, with no further information.  Am I doing this correctly? I watched the traffic in Fiddler, and it seems that it is dropping off the layer id in the request uri.  The response looks like a description of all the layers on the service, not just the one I was after.  This would account for the "invalid response".  But what is the correct way to load and display an Annotation Layer then?   Thanks for any help. ...

I've found some old discussions saying that annotation layers are not supported by Runtime 10.2, but that there were plans to support it in future releases.  However, I cannot find any information about support in 100.2.   As an example, the following layer does not appear for us in the Runtime control: Layer: Addresses (ID: 1)  If annotation layers are not supported, is there a workaround, either in the app or on the server?  I am able to create a renderer in the app, and see the features; I just don't have the correct text.   ...

I am trying to consume WMTS content using ArcGIS Runtime 100.1, and can't get it to work when the server only supports KVP service mode.  There was a way in 10.2 to set the service mode on the layer object, but I don't see it in the 100.1 API.   For example, a public service with this problem is: http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts?Version=1.0.0&service=wmts&request=getcapabilities My code is something like this:    WmtsService service = new WmtsService(_TiledUri);    await service.LoadAsync();    WmtsServiceInfo info = service.ServiceInfo;    _TiledLayer = new WmtsLayer(info.LayerInfos.ToArray()[0]);    _MapView.Map.Basemap.BaseLayers.Add(_TiledLayer);    _TiledLayer.IsVisible = true;    await _TiledLayer.LoadAsync();   The service metadata loads just fine.  However the layer itself does not display.  In fact, there is no further web traffic to fetch the tiles at all. The GetCapabilities call on the above uri contains: <ows:Operation name="GetTile"> <ows:DCP>     <ows:HTTP>        <ows:Get xlink:href="http://opencache.statkart.no/gatekeeper/gk/gk.open_wmts?">           <ows:Constraint name="GetEncoding">              <ows:AllowedValues>                 <ows:Value>KVP</ows:Value>              </ows:AllowedValues>           </ows:Constraint>        </ows:Get>     </ows:HTTP> </ows:DCP> </ows:Operation> I suspect that since RESTful is not supported, this is the problem.  10.2 would allow you to set the service mode on the layer, and would also automatically try KVP if RESTful failed.  How can a similar thing be done in 100.1? ...

I see that WMTS layers are already supported in ArcGIS Runtime 100.1.  I came across some API documentation showing a WMSLayer class, which is from version 100.2.  Am I correct that 100.2 has not been released yet? Are there any plans, hopes, dreams, or wishes to support WFS in future releases? ... View more
