Unfortunately the Native SDK (and the Unity Plugin) do not support geobased AR at the moment. Only the JS API, Cordova and Xamarin Extension. As for the change of the layout, yes this is done via JS.
Thx and greetings
Okay, Thank you Nikola.
Is Wikitude SDK provide any location geo based AR functionality for native android?
I want to customize marker design and put multiple markers at diff-diff latitude and longitude.
Please let us know your feedback.
