Android Question TileOverlay Opeen Street Maps

[Zoran Vujacic]

Hi everyone!

I need advice.
I want to add Sea marks only, background transparent (http://tiles.openseamap.org/seamark/{z} /{x}/{y}.png)
in the main fcvMap (fcvMap.TileServer="https://a.tile.openstreetmap.fr/osmfr/")

How can I add marks (Overlay tiles) via the base maps?

Thanks!
