        this.marker.on(GoogleMapsEvent.MARKER_CLICK)
      }
      );

    });

  }

Any Errors in the Console? Do you have set the GOOGLE_MAPS_ANDROID_API_KEY correctly?

yes , when i edite code it’s worked
my edite code

let options: GoogleMapOptions = {
camera: {
target: {
lat: 24.711512, // Default position
lng: 46.669891 // Default position
},
zoom: 17,
}
};
this.map = GoogleMaps.create(‘map_canvas’, options);

but when i put full code not worked

So you have any Errors in Console?

no error and div map is empty

So the only thing you change is

target: myLocation.latLng,

to

target: {
  lat: 24.711512, // Default position
  lng: 46.669891 // Default position
}

and then it works?

if i need get current location not Default location

i don’t understand. Is what i mention the Change that works for you?

not worked alos i need open map in current location

Can you try to just run this:

LocationService.getMyLocation().then((myLocation: MyLocation) => {
  console.log(myLocation);
}

and check what is logged out?
