Webview not recognizing the location permission of phone
I have a secure website that uses the watchPosition call to show my location. It works fine if I go to it in a browser. I used an online service to create an apk file ( i think it was appgeyser), and it works fine with that apk. I then installed the Android Studio so that I could make my own apk so that I could keep my privacy and have more control. The problem is that everything works just fine EXCEPT it will not recognize the location permission that the phone gives. Everything looks normal, the user is asked to accept the location permission, the location permission is set on the phone, but I still get the 'user denied geolocation' message. I made the code as simple as I know how, and have looked muchly on the internet for solution and have tried many things, but to no avail. Please help so that I can resolve this so that I can continue developing my application. Thanks.

Verizon Samsung Galaxy S9
Android 8.0.0 Oreo

Keep Mobile Data turned on
+ various others
Development
Secure website: https://www.crudepinpoints.com
Android Development Studio 3.2.1
I run the above from Android Studio using my phone plugged into a usb port. The following happens when the program loads on the phone:
Phone asks: "Allow 'CrudePinpoints' to access this device's location. Deny Allow"
I choose Allow.
Phone responds via a toast: "Permission Granted"
My program responds when watchPosition is invoked : "Error: User denied Geolocation"
I go to the settings and location is enabled: Settings -> Apps -> CrudePinpoints = Permissions = Location
All of the code is below, both for the javascript and the java in the android app.
