Add a Geometry to the GeojsonSource. Data will be parsed from collection to String in a worker thread and use main thread to pass this data to gl-native.
In order to capture events when actual data is drawn on the map please refer to Observer API and listen to MapEvents.STYLE_DATA_LOADED or MapEvents.MAP_LOADING_ERROR with type = source if data parsing error has occurred.
type = source
Note: This method is not thread-safe. The Geometry is parsed on a worker thread, please make sure the Geometry is immutable.
