Is it possible to draw H3 (https://www.gislounge.com/h3-open-source-geospatial-indexing-system/) geo overlay for android? Maybe some maps API supporting this layer? I know that for example you can draw any polygon for map - but if there will be a lot of polygons, it will be too slow to draw. GeoJSON doesn't support transparency for color filling. If we will use tile overlay - there is rectancle pictures - how to decode H3 hexagons to show it in rectangle pictures?
