GemGlSurfaceAdapter

class GemGlSurfaceAdapter(val context: Context)

GemGlSurfaceAdapter will create a MapView using a GemSurfaceContainerAdapter.

If GemSdk wasn't initialized yet then this surface will call GemSdk.initSdkWithDefaults inside of init block.

A MapView is created by default. To disable this please use doCreateDefaultMapView = false
