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

fun onScale(focusX: Float, focusY: Float, scaleFactor: Float)

Must be called when androidx.car.app.SurfaceCallback.onScale is triggered.

onScroll

fun onScroll(distanceX: Float, distanceY: Float)

Must be called when androidx.car.app.SurfaceCallback.onScroll is triggered.

onStableAreaChanged

fun onStableAreaChanged(stableArea: Rect)

Must be called when androidx.car.app.SurfaceCallback.onStableAreaChanged is triggered.

onSurfaceAvailable

fun onSurfaceAvailable(surfaceContainer: GemSurfaceContainerAdapter)

Must be called when androidx.car.app.SurfaceCallback.onSurfaceAvailable is triggered.

onSurfaceDestroyed

fun onSurfaceDestroyed()

Must be called when androidx.car.app.SurfaceCallback.onSurfaceDestroyed is triggered.
