loadMap(){
// create a new map by passing HTMLElement
let element: HTMLElement = document.getElementById(‘map’);
let map = new GoogleMap(element);
// create LatLng object
let ionic: GoogleMapsLatLng = new GoogleMapsLatLng(43.0741904,-89.3809802);

// create CameraPosition
let position: CameraPosition = {
target: ionic,
zoom: 18,

};

// listen to MAP_READY event
map.one(GoogleMapsEvent.MAP_READY).then(() => {
// move the map’s camera to position
map.moveCamera(position); // works on iOS and Android
});

// create new marker
let markerOptions: GoogleMapsMarkerOptions = {
position: ionic,
title: ‘Ionic’
};

map.addMarker(markerOptions)
.then((marker: GoogleMapsMarker) => {

Your are using Native Maps, unless you update your project to Ionic V3 you won’t be able to test native map in your computer, yes in your phone after generate the apk.
