ANDROID Large GeoJSON File Loading on a Map

[MAXBAF1]

I have a GeoJSON file of approximately 100 MB containing 260,000 polygons. When I load this file as a data source and add its layer to the map, the application experiences significant lag, and rendering takes a long time. Sometimes, it even crashes with an OutOfMemory error. Is there a way to speed up the layer addition process and prevent this error?

style.addSource(GeoJsonSource(MapConstant.ID_GEOJSON_SOURCE, geojson))
val layer = LineLayer(MapConstant.ID_GEOJSON_LAYER, MapConstant.ID_GEOJSON_SOURCE)
style.addLayer(layer)

I would consider serving the data tiled instead of all at once.

Yep GeoJSON is not really intended to be used for this much data.

Take a look at Tippecanoe: https://github.com/felt/tippecanoe

Both MBTiles and PMTiles can be used without a tile server with MapLibre Native.
