moveTo

@NonNull
public static MapItemKeyFrameTrack moveTo(@NonNull
                                          java.util.List<GeoCoordinatesKeyframe> keyframes,
                                          @NonNull
                                          Easing easing,
                                          @NonNull
                                          KeyframeInterpolationMode interpolationMode)
                                   throws MapItemKeyFrameTrack.InstantiationException

Creates a map item position keyframe track. It enables animations over the geographical coordinates where the map item is positioned.

Parameters:: keyframes -
The list of keyframes that specify how the map item position changes over time.; easing -
The easing to apply during keyframe interpolation.; interpolationMode -
The type of interpolation done between keyframe values.
Returns:: MapItemKeyFrameTrack instance.
Throws:: MapItemKeyFrameTrack.InstantiationException -
If the supplied keyframe list is empty or first keyframe duration is not 0.

polylineProgress

@NonNull
public static MapItemKeyFrameTrack polylineProgress(@NonNull
                                                    java.util.List<ScalarKeyframe> keyframes,
                                                    @NonNull

                                                    KeyframeInterpolationMode interpolationMode)
                                             throws MapItemKeyFrameTrack.InstantiationException

Creates a keyframe track used to animate the progress of a polyline.

Each scalar keyframe specifies the progress property (as passed to MapPolyline.setProgress(double)) at key points of the animation.
