I am building an app using the ionic framework. The primary function of the app is based around google maps. I have used this tutorial which uses the java script google maps API. Everything works perfectly when I run ionic lab or ionic serve however when using an android emulator by running: ionic cordova run android the place where the google maps should be is totally blank. I do not get any error messages either. Additionally I am using cordova version 7.0.1 and ionic version 3.5.0. I have tried both the solutions listed in this question and the problem is still occurring.
Here is the hopefully relevant parts of config.xml as the other post suggested
<content src="index.html" />
<access origin="*" />
<access origin="http://maps.google.com" />
<access launch-external="yes" origin="geo:*" />
<allow-navigation href="http://ionic.local/*" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
<allow-intent href="tel:*" />
<allow-intent href="sms:*" />
<allow-intent href="mailto:*" />
<allow-intent href="geo:*" />
<access origin="*" />
<allow-navigation href="*" />
<allow-intent href="*" />
<allow-intent href="http://maps.google.com" />
<preference name="webviewbounce" value="false" />
<preference name="UIWebViewBounce" value="false" />
<preference name="DisallowOverscroll" value="true" />
<preference name="android-minSdkVersion" value="16" />
<preference name="BackupWebStorage" value="none" />
<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="3000" />
<platform name="android">
<allow-intent href="market:*" />
Additionally here is the index.html where I link to the api
<script src="https://maps.google.com/maps/api/js?key=
MY_ACTUAL_API_KEY" type="text/javascript"></script>
<script src="cordova.js"></script>
As requested here is the ts html and css for the home page which uses google maps html

ts hopefully just the relevant parts

}
ionViewDidLoad(){
console.log(this.mapInitDid)
this.mapInitDid=false;
this.initMap();
}
//initMap() is supposed to load the map and it doesnt on the android
//emulator
initMap(){
this.geolocation.getCurrentPosition().then((position) => {
let latLng = new google.maps.LatLng(38.2527, -85.7585)
pos=new google.maps.LatLng(38.2527, -85.7585);
console.log(this.havePerms);
console.log(latLng)
if(this.havePerms==1){
latLng = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
}
let mapOptions = {
center: latLng,
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
this.map = new google.maps.Map(this.mapElement.nativeElement, mapOptions);
}, (err) => {
console.log(err);
});
console.log("map is go");
this.mapInitDid=true;
// this.markerOnLocal();
}
}
Any help would be much appreciated

As it turns out I was in fact solving the wrong problem. The api was loading fine however the device was not running any of the code inside
this.geolocation.getCurrentPosition().then((position) => {
...
});
which contained all of my code for generating the map. To solve the problem I took everthing inside of this section not pertaining to the users location and put it inside initMap()
which is the method where this.geolocation.get...
was located
