I'm in the process of building a mobile app and within it I have a map plugin that is utilizing Esri.ArcGISRuntime.Xamarin.Android nuget package (version 100). I have created a C# class which implements a LinearLayout and on Initialize, I construct my Esri.ArcGISRuntime.UI.Controls.MapView and call AddView(_myMapView) followed up with a load layer method that constructs a map consuming a Streets basemap.
Everything compiles and the layout appears in my app and I see the Powered by ESRI logo; however, nothing displays. The map appears black and no other code fires if I drag or pinch my finger over the control. I did wire up the LoadStatusChanged event for my map and I do achieve a loaded status, again nothing is visible.
