Answer 1

Had the same problem, in my case I used ValueAnimator

    static public void rotateMarker(final Marker marker, final float toRotation) {

    ValueAnimator animator = ValueAnimator.ofFloat(marker.getRotation(), toRotation);
    animator.setDuration(duration);
    animator.setInterpolator(new AccelerateDecelerateInterpolator());
    animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            float rotate = Float.parseFloat(animation.getAnimatedValue().toString());
            marker.setRotation(rotate);
        }
    });
    animator.start();
}

You would want to use MarkerOption rotation method

 public MarkerOptions rotation (float rotation)

Sets the rotation of the marker in degrees clockwise about the marker's anchor point. The axis of rotation is perpendicular to the marker. A rotation of 0 corresponds to the default position of the marker. When the marker is flat on the map, the default position is North aligned and the rotation is such that the marker always remains flat on the map. When the marker is a billboard, the default position is pointing up and the rotation is such that the marker is always facing the camera. The default value is 0.

Returns the object for which the method was called, with the new rotation set.
