AdMob ads are not showing in my Android game

Hello,

I am trying to integrate AdMob to my Android Game.

I am not getting any errors in the editor, but when I try to open the game in my phone, I am getting:

Unfortunately yourGame has stopped.

I am using Unity 5.3.4f1 Personal, and also updated my SDK.

This is the demo script that comes with the Google Mobile Ads Sample project found on GitHub.

I created an empty scene and attached this script to the Main camera and then build just this scene.

I am sorry if this is a very long script, but I thought it would be better if I add it here.

Code (CSharp):

1. using System;
2. using UnityEngine;
3. using GoogleMobileAds;
4. using GoogleMobileAds.Api;
5.  
6. public class GoogleMobileAdsDemoHandler : IDefaultInAppPurchaseProcessor

10.     //Will only be sent on a success.
11.     public void ProcessCompletedInAppPurchase(IInAppPurchaseResult result)
12.     {
13.         result.FinishPurchase();
14.         GoogleMobileAdsDemoScript.OutputMessage = "Purchase Succeeded! Credit user here.";
15.     }
16.  
17.     //Check SKU against valid SKUs.
18.     public bool IsValidPurchase(string sku)
19.     {
20.         foreach(string validSku in validSkus)
21.         {
22.             if (sku == validSku)
23.             {
24.                 return true;
25.             }
26.         }
27.         return false;

31.     public string AndroidPublicKey

Ok I fixed it by deleting the code inside Start(), and now my game opens without errors.

But when I try to show an Interstitial ad, it is not showing. The adUnit in my code is the same as the one in my AdMob account.

What could be the problem ?

 

Can anyone help me please ?

 

Have you ever got this working? It's amazing how this just doesn't work properly.

Sorry for the late reply, honestly I didn't find a solution, and I shifted to Unity Ads
