I have an application writen in Xamarin Forms targeting primarily Android, with ArcGISRuntime 100.5. Everything works like a charm. After updating to version 100.6 I am getting a exception: "Default constructor not found for type Esri.ArcGISRuntime.Xamarin.Forms.Platform.Android.MapViewRenderer" when open the Page with MapView control. Anyone experienced something like that? at System.RuntimeType.CreateInstanceMono (System.Boolean nonPublic, System.Boolean wrapExceptions) [0x0007b] in <d4a23bbd2f544c30a48c44dd622ce09f>:0 at

I’m looking for something like Map.FlashGeometry from WPF SDK but in Xamarin Forms.  Should I use Xamarin’s Animation methods instead? Any examples? ... View more

Hello, I have been struggling with a weird exception lately. My context: - Xamarin Forms (testing on a Android device) - Basemap/BaseLayers loaded successfully - While loading some feature tables from a SQLite geodatabase (multiple tables are loaded properly except by two similar ones) Relevant parts: try {     var geodatabase = await Geodatabase.OpenAsync(<path>);     var featureTables = geodatabase.GeodatabaseFeatureTables;     foreach (var featureTable in featureTables)     {         var featureLayer = new FeatureLayer(featureTable);         featureLayer.Name = featureTable.TableName;         _mapView.Map.OperationalLayers.Add(featureLayer);  //Exception thrown on the ase_ctaponto and ase_cteponto     } } catch (Exception ex) {     throw ex; //Breakpoint here } The exception: Type: ArcGISException Message: "Not found: Field does not exist."
