Implementing Admob

Hello, I'm fairly new to Unity, but I made my own app and I'm just trying to implement ads from admob. The guide on admob is a little difficult to follow, I tried it but couldn't get it working, so I followed tutorials online, to no avail.
This is my code, with appID removed to protect privacy

Code (CSharp):

1. using System;
2. using System.Collections;
3. using UnityEngine;
4. using GoogleMobileAds.Api;
5.  
6. public class Ads : MonoBehaviour
7. {
8.     private BannerView bannerView;
9.  
10.  
11.     [SerializeField] private string appID = "";
12.  
13.     [SerializeField] private string bannerID = "ca-app-pub-3940256099942544/6300978111";
14.  
15.     public void start()
16.     {
17.         MobileAds.Initialize(appID);
18.     }
19.  
20.  
21.        public void ClickAd()
22.     {
23.         this.RequestBanner();
24.     }
25.  
26.         private void RequestBanner()
27.     {
28.         bannerView = new BannerView(bannerID, AdSize.Banner, AdPosition.Top);
29.         AdRequest adRequest = new AdRequest.Builder().Build();
30.         bannerView.LoadAd(adRequest);
31.     }
32.  
33. }

I have it linked to a button with the function set as ClickAd() but nothing happens. The Console says, "Dummy ctor", "Dummy CreateBannerView", "Dummy LoadAd". What am I doing wrong?

Edit: Also, just to be sure, I have downloaded the plugin, and have followed everything from https://developers.google.com/admob/unity/start

 

Have you tested it on your Android device? Ads are not shown in the editor if you are expecting that to happen.

 

I thought that might be the case, so I exported it and tested it on my android, they still don't display

 

Bump

 

Easier to debug when you use the android logger with the device plugged into your computer.
Otherwise hard to tell what the issue is.

 

Sorry, I'm quite new to developing apps, how would I got about this? I did some research and I guess it's done in Android Studio, right? Do I need to import my apk to Android Studio?

Edit: I have logcat and everything brought up, it just says no debuggable processes

 

Nevermind, I think I got the error. Can't determine the cause of it though.

If that's related to ads it might be unable to fetch any ads to display.

Are you using the test/developer ad id to test? Sometimes it takes a few days before the real ad id will start to display ads.
