Clustering

[Nbzh]

Hello,

I'm trying to implement a map with markers and clusters. I 'm using a Protomaps style.

I'm following this example : https://github.com/maplibre/maplibre-plugins-android/blob/main/app/src/main/java/org/maplibre/android/plugins/testapp/activity/annotation/ClusterSymbolActivity.java

but I can't make it work. I can display my 157 markers but if I add the ClusterOptions there is nothing anymore displayed on the map

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        MapLibre.getInstance(this)
        binding = ActivityTestMaplibBinding.inflate(layoutInflater)
        setContentView(binding.root)
        binding.mapView.onCreate(savedInstanceState)
        val clusterOptions = ClusterOptions()
            .withColorLevels(
                arrayOf(
                    Pair(100, Color.RED),
                    Pair(50, Color.BLUE),
                    Pair(0, Color.GREEN)
                )
            )
        binding.mapView.getMapAsync { map ->
            map.setStyle(
                Style.Builder()
                    .fromJson(getJsonStringFromAssets(this, "map/styles.json"))
            ) { style ->
                style.addImages(
                    hashMapOf(
                        "ic_associated" to BitmapFactory.decodeResource(
                            getResources(),
                            R.drawable.ic_marker_lumio
                        ),
                        "ic_not_associated" to BitmapFactory.decodeResource(
                            getResources(),
                            R.drawable.ic_marker_no_lumio
                        ),
                        "ic_malfunction_new" to BitmapFactory.decodeResource(
                            getResources(),
                            R.drawable.ic_marker_malfunction_new
                        ),
                        "ic_malfunction_qualified" to BitmapFactory.decodeResource(
                            getResources(),
                            R.drawable.ic_marker_malfunction_qualified
                        ),
                        "ic_malfunction_solved" to BitmapFactory.decodeResource(
                            getResources(),
                            R.drawable.ic_marker_malfunction_resolved
                        )
                    )
                )
                symbolManager =
                    SymbolManager(binding.mapView, map, style, null, null, clusterOptions)
                symbolManager.setIconAllowOverlap(true)
                symbolManager.iconIgnorePlacement = true
            }
            map.cameraPosition = CameraPosition.Builder().target(LatLng(0.0, 0.0)).zoom(1.0).build()
            viewModel.fullParksWithStreetlamps.observe(this) { parks ->
                lifecycleScope.launch(Dispatchers.IO) {
                    val symbolOptions = mutableListOf<SymbolOptions>()
                    parks.mapNotNull { p -> if (p.park.isBusiness) p.park.id else null }.let {
                        viewModel.selectParkStreetlamps(it).let { mapStreetlamps ->
                            mapStreetlamps.map { s ->
                                symbolOptions.add(
                                    SymbolOptions()
                                        .withGeometry(Point.fromLngLat(s.longitude, s.latitude))
                                        .withIconImage(s.getMarkerIconName())
                                )
                            }
                        }
                    }
                    symbolManager.create(symbolOptions).also {
                        Timber.tag("MapLibTest").d("symbols: ${it.count()}") //157
                    }
                }
            }
        }
    }

Second question : is it possible to create groups of cluster ? Having some markers in the blue clusters and others in green clusters

Thank you for your help.
