In example of using yandexmapkit library called "yandexmapkit-sample" which I get from https://github.com/yandexmobile/yandexmapkit-android, when I started any example that have Balloon in it's code, text color and background color of Balloon are the same.
Can I change these colors somehow?
Overlay overlay = new Overlay(mMapController);
OverlayItem kremlin = new OverlayItem(new GeoPoint(55.752004 , 37.617017), res.getDrawable(R.drawable.kreml));
BalloonItem balloonKremlin = new BalloonItem(this,kremlin.getGeoPoint());
balloonKremlin.setText("Московский Кремль. Здесь можно ещё много о чём написать.");
balloonKremlin.setOnBalloonListener(this);
kremlin.setBalloonItem(balloonKremlin);
overlay.addOverlayItem(kremlin);
