"@ionic-native/core": "^4.7.0", "cordova-plugin-googlemaps": "^2.4.6", "@ionic-native/google-maps": "^4.8.2", "@ionic-native/core": "^4.7.0", Current behavior:

When creating a marker cluster and set the url of a custom image, it does not load on IOS. The error I get in runtime with xcode is:

2018-12-09 17:15:04.883697+0000 Chalk[51721:3936880] [fail] url = http://localhost:8080//./assets/images/map-cluster.png 2018-12-09 17:15:04.888974+0000 Chalk[51721:3936880] *** Terminating app due to uncaught exception 'GMSThreadException', reason: 'The API method must be called from the main thread'

Note, I am also trying with /assets/... , 'assets/...' , ../assets/... in additon to ./assets

The behaviour on iOS simulator is that it crashes to the desktop.

The behaviour on a real iOS device causes the app to freeze

It works perfectly on android!

Expected behavior:

I expect the map marker to appear :)

Related code, data or error log (please format your code or data):

      this.map.addMarkerCluster({
        maxZoomLevel: 9,
        markers: [{
          map: this.map,
          position: {
            lat: marker.lat,
            lng: marker.lng
          },
          title: marker.name,
          data: marker
        }],

Please share your project files on GitHub repository

stevebrowndotco commented 5 years ago

I can't show you my project files for various reasons, so I will have to get a boilerplate repo and demonstrate by uploading that.

stevebrowndotco commented 5 years ago

Hi @wf9a5m75 the problem is further described here https://forum.ionicframework.com/t/ionic-native-google-maps-custom-icon/63660

wf9a5m75 commented 5 years ago

You just share the link. The comments on the forum were posted on various period. Code is always changing. So, it's not valuable information at all.

As I said, please share your project files on Github repository. You can create a demo project at least. If you decline any contribution, I can't help you at all.

stevebrowndotco commented 5 years ago

Hi @wf9a5m75 , I'm just sharing the link so you can see something in the meantime.

I can also confirm that the link provides a useful workaround for me (prefixing with /www), which means if it's a bug it is still apparent in version I posted above (because I need to only do this on IOS).

Hope this helps for now 👍

wf9a5m75 commented 5 years ago

Unfortunately there is no valuable information. If you can't create a demo, I will close this thread.

wf9a5m75 commented 5 years ago

Since there is no additional information, I close this thread.

I'm able to reproduce this issue using the https://github.com/mapsplugin/ionic-googlemaps-quickdemo-v4 repository:

Per stevebrowndotco's comment, changing the "./" to "www/" fixes the issue.
