Marker features does not work under Android

[YordanYanakiev]

Just compiled the android sample and tried just to add this row to the original code

mapControl.Map.Layers.Add( PointLayerSample.CreateRandomPointLayerWithLabel( new MemoryProvider( new Point( 10, 10 ) ) ) );

it result immediately on the run an "System.NotImplementedException: The method or operation is not implemented." in Mapsui.Rendering.OpenTK in PlatformLabelBitmap.cs

Probably it is an issue related to the libraries, please - note which libraries You are using into the samples for android. ( currently I am using the nuget version of MapsUI )

is there some specific source for OpenTK which i shall use for Android ?.

Sorry, I did not have this clear. Android really does not have an implementation for OpenTK labels. This is a part that needs to be implemented per platform.

While iOS and desktop have:

Android labels is one of my priorities for the coming weeks.

Unfortunately no marker is shown with or without label feature. It is always turn white square.
If it is possible for a working sample at least for a simple marker without any label - it will clarify a lot.

If you download the code and open the solution there is a Android sample with bitmap symbols under de Samples folder called Mapsui.Samples.Android.
