Description

Dear Developer:
I am try to use Mapbox to repace Baidu in abroad. and there are many points need to be draw in the same time ,I search the document of Mapbox, and use CircleManager create function .and
put many points to the optionlist .the code like this:
CircleOptions options = new CircleOptions();

            options.withLatLng(latLng)
                    .withCircleColor(PropertyFactory.circleColor(trackControlView.getColor(cell)).getValue())
                    .withData(null)
                    .withCircleRadius(6.0f);
             optionsList.add(options);

circleManager.create(optionsList);

When points are more and more, the interface is stuck。
