Class Gestures

Gestures (API Reference)

- - com.here.sdk.gestures.Gestures

```
public final class Gestures
extends NativeBase
```
Use this class to process touch events from the platform and detect gesture induced actions on the map view. Please note that this class holds strong references to the gesture listeners. On Android Auto, processing touch events is not needed. Instead, gestures get detected by android auto platform and provided via callbacks. For more information see onClick, onFling and onScale methods in https://developer.android.com/reference/androidx/car/app/SurfaceCallback.
