Add north to the map view

[LionelGOUBET]

Hi,

I developp with ArcGIS Runtime SDK for Android 100.1.0 and I would like add a north information in the map with the north image or others (vector, etc?)
What the best way to build this ?
What are the events to observe ?

Do you a sample ?

Thanks for your help
