Cluster / Marker showing inconsitent behaviour about android-maps-utils

[broady]

Are you calling clusterManager.cluster() after you call addItems?

[broady]

Thanks for the report - do you have a minimal test case I can debug against?

Thanks for the quick response :)
so the case is.
I initialize map and add clusterMangaer and hook listners and then call addItems function in which i'm starting AsyncTask passsing clustermanger object to it and there i'm getting coordinates data via http request and on success of request m adding coordinates in clustermanger .. It works fine some of time but sometimes markers don't appear untill i zoom in or zoom out the map .. i've debugged i'm getting no error in data and even markers are there but they only show up on zoom in or zoom out .

I have a method that setMarkersOnMap(){...}
1.At first I clear items mClusterManager?.clearItems()
2.I add items to cluster manager by mClusterManager?.addItem(poi)
3.Simultanieously i the same loop I take only first 6 items in order to count LatLngBounds boundBuilder.include(poi.latLng)
4. When I leave loop I animateCamer according to the LatLngBounds
5. I call mClusterManager?.cluster()

When I call the function first time it works fine, after I call it again markers are not present unless I zoom out - what force IdleListener to make clustering. My Code is

protected fun setMarkersOnMap(poiList : List<POI>){
        clearMap()
        if(poiList.isEmpty()){
            return
        }

        val boundBuilder  : LatLngBounds.Builder = LatLngBounds.builder()

        poiList.forEachIndexed { index, poi -> run{
            poi.icon = getIconForType(poi.typeName)
            poi.setAnchor(0.5f, 0.6f)

             mClusterManager?.addItem(poi)

            // Add new coordinates in order to establish map zoom
            if (index < 6)
                boundBuilder.include(poi.latLng)
        }}

       mClusterManager?.cluster()
        // Adjust Map zoom to Marker position
        val mapPadding = Tools.dpToPx(12) // offset from edges of the map in pixels
        val mCurrentLatLng : LatLng  = LatLng(mLocation.latitude, mLocation.longitude)
        boundBuilder.include(mCurrentLatLng)
        val latLngBounds = boundBuilder.build()


        mGoogleMap?.animateCamera(CameraUpdateFactory.newLatLngBounds(latLngBounds, mapPadding), cameraUpdateListener)

            if(!isClusterManagerListenToMap){
                handler.postDelayed({
                    // listen for changes. After Zoom will be updated we set ClusterManager listener
                    isClusterManagerListenToMap = true
                    mGoogleMap?.setOnCameraIdleListener(mClusterManager)
                    mClusterManager?.cluster()
                }, 500)
            }else{
                handler.postDelayed({
                    mClusterManager?.cluster()
                }, 500)
            }
    }
