The following code sample demonstrates how to add a 3D polygon and position
it in 3D space by calling theaddPolygonmethod. To use this code sample, follow the instructions inSetupandAdd a 3D map to your appto set up your Android Studio project with a basic 3D map. Then, add the following code to theMainActivity.ktfile:
