Creating animation of changing radius.

[alexd555]

Hi,

I want to change radius online and then I use with setHoles.
But signature of this function is List<? extends List>

I tried it:
private static List<? extends List> createHole2(LatLng center, float radius) {
int points = 50; // number of corners of inscribed polygon

    double radiusLatitude = Math.toDegrees(radius / (float) EARTH_RADIUS);
    double radiusLongitude = radiusLatitude / Math.cos(Math.toRadians(center.latitude));

    List<? extends List<LatLng>> result = new ArrayList<>(points);

    double anglePerCircleRegion = 2 * Math.PI / points;

    for (int i = 0; i < points; i++) {
        double theta = i * anglePerCircleRegion;
        double latitude = center.latitude + (radiusLatitude * Math.sin(theta));
        double longitude = center.longitude + (radiusLongitude * Math.cos(theta));
        List <LatLng> l = new ArrayList<>();

        l.add(new LatLng(latitude, longitude));
        result.add(l);
    }

    return result;
}

But I got error
