The following code sample demonstrates how to add a 3D polygon and position
it in 3D space by calling the
addPolygon
method. To use this code sample, follow the instructions in
Setup and
Add a 3D map to your app
to set up your Android Studio project with a basic 3D map. Then, add the following code to the
MainActivity.kt file:
