app crashed when setupMarkerCluster

[weijyewang]

I'm trying to enable clustered marker in android using angular 6.

My code was rather simple, and I had no idea when the app crashed (it exited to the emulator home screen automatically) when it ran this line of code GoogleMapsUtils.setupMarkerCluster(this.mapView, markerSet);

Here's the code snippet: import section:

import { MapView, Marker, Position } from 'nativescript-google-maps-sdk';
import * as GoogleMapsUtils from "nativescript-google-maps-utils"

inside the function

let markerSet = [];
this.journeys.forEach(journey => {
	let theMarker: Marker = new Marker();
	theMarker.position = Position.positionFromLatLng(journey.latitude, journey.longitude);
	theMarker.title = journey.vehicleRegistrationNumber;
        theMarker.snippet = journey.vehicleRegistrationNumber;
	markerSet.push(theMarker);
});

setTimeout(() => {
	GoogleMapsUtils.setupMarkerCluster(this.mapView, markerSet);
	this.zoomCenterOnMultipleMarkers();
}, 1000)

Does anyone get it to working on angular? Please help

remove this mapView._markers.push(marker); statement form this method setupMarkerCluster() in index.android.ts.

There is no _markers property in the MapView class

Secondly, There should be minimum 5 markers to showing cluster

[sedrak1987]

dear where is index.android.ts file?(maybe in node_modules, if yes, then why I must change core files)

[fawadmukhtar]

@sedrak1987 because the app is crashing at that point. you need to fork it and update that file to get a expected result

[sedrak1987]

yes, but after plugin update or node_modules remove in every time I need remove that line. Right?

[fawadmukhtar]

No, when you fork it and use your own. that's control from your package.json file

[sedrak1987]

can you give me instruction steps how do it, please?

@sedrak1987

1. Fork this project in Github
2. Do whatever changes neccessary like what @fawadmukhtar suggested in your forked new repo.
3. Publish to npm or Nativescript plugin market (https://docs.nativescript.org/plugins/building-plugins#step-4-publish-your-plugin)
4. Install back your published version.

[sedrak1987]

Thanks a lot. Will try later when will get free time

[weijyewang]

Remember to uninstall this original nativescript plugin before using your forked version. Else you will have namespace conflict
