Hello,

Welcome to our Microsoft Q&A platform!

To display the google Admob ads in Xamarin.Forms, we need to install the required packages for the native platform project: Xamarin.GooglePlayServices.Ads for Android and Xamarin.Firebase.iOS.AdMob for iOS. Then try creating a customView which display the ads and render the ads in native project using custom renderer.

   public class AdsView : View  
   {  
       //you could add some properies to define the ads view  
       public AdsView()  
       {  
           this.BackgroundColor = Color.Accent;  
       }  
   }

Custom renderer class

   [assembly: ExportRenderer(typeof(AdsView), typeof(AdsViewRenderer))]    
   namespace AdMobTestSample.Droid  
   {  
       public class AdsViewRenderer : ViewRenderer  
       {  
           Context context;  
           public AdsViewRenderer(Context _context) : base(_context)  
           {  
               context = _context;  
           }  
           protected override void OnElementChanged(ElementChangedEventArgs<View> e)  
           {  
               base.OnElementChanged(e);  
               ...  
               var adView = new AdView(Context);  
               adView.AdUnitId = "Your AdMob id";  
               var requestbuilder = new AdRequest.Builder();  
               adView.LoadAd(requestbuilder.Build());  
               SetNativeControl(adView);  
           }  
       }  
   }

dear zhang:
I use this thread to show interstitial ads.
(https://www.c-sharpcorner.com/article/google-admob-display-ads-in-xamarin-forms/)

   My code is below:  
using Android.App;  
using Android.Content;  
using Android.OS;  
using Android.Runtime;  
using Android.Views;  
using Android.Widget;  
using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using Android.Gms.Ads;  
using Android.Gms.Ads.Interstitial;  

 
    namespace quPlayer.Droid  
{  
  
    public class AdInterstitial_Droid : IAdInterstitial  
    {  
        InterstitialAd interstitialAd;  
  
        public AdInterstitial_Droid()  
        {  
            interstitialAd = new InterstitialAd(Android.App.Application.Context);  
  
            // TODO: change this id to your admob id    
            interstitialAd.AdUnitId = "Your AdMob id";  
            LoadAd();  
        }  
  
        void LoadAd()  
        {  
            var requestbuilder = new AdRequest.Builder();  
            interstitialAd.LoadAd(requestbuilder.Build());  
        }  
  
        public void ShowAd()  
        {  
            if (interstitialAd.IsLoaded)  
                interstitialAd.Show();  
  
            LoadAd();  
        }  
    }  
}  

   The error below:  
    ![148518-11.png][1]

JarvanZhang 23,971

This is because the 'InterstitialAd' class is an abstract class which can not be used directly. Try creating a custom class to extends the 'InterstitialAd' class and overide the related properties/methods.

public class MyInterstitialAd : InterstitialAd
{
    private Context context;
    public MyInterstitialAd(Context context)
    {
        this.context = context;
    }
    public override string AdUnitId => throw new System.NotImplementedException();
    public override FullScreenContentCallback FullScreenContentCallback { get => throw new System.NotImplementedException(); set => throw new System.NotImplementedException(); }
    public override IOnPaidEventListener OnPaidEventListener { get => throw new System.NotImplementedException(); set => throw new System.NotImplementedException(); }
    public override ResponseInfo ResponseInfo => throw new System.NotImplementedException();
    public override void SetImmersiveMode(bool p0)
    {
        throw new System.NotImplementedException();
    }
    public override void Show(Activity p0)
    {
        throw new System.NotImplementedException();
    }
}

There is something wrong with the this part in the doc. Sorry for that.

Dear Zhang:
Thank you very much.
I have used your code.
But some errors be in.
interstitialAd.AdUnitId = "Your AdMob id"; // the notify is AdUnitId is read only.
How should I do?

    using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Android.Gms.Ads;
using Android.Gms.Ads.Interstitial;

namespace quPlayer.Droid
{

    public class AdInterstitial_Droid : IAdInterstitial
    {
        MyInterstitialAd interstitialAd;

        public AdInterstitial_Droid()
        {
            interstitialAd = new MyInterstitialAd(Android.App.Application.Context);

            // TODO: change this id to your admob id  
            interstitialAd.AdUnitId = "Your AdMob id";            
            LoadAd();
        }

        void LoadAd()
        {
            var requestbuilder = new AdRequest.Builder();
            interstitialAd.LoadAd(requestbuilder.Build());
        }

        public void ShowAd()
        {
            if (interstitialAd.IsLoaded)
                interstitialAd.Show();

            LoadAd();
        }
    }
}

System prompt

Interstitialad.adunitid this property cannot be written

in the code line:
// TODO: change this id to your admob id
interstitialAd.AdUnitId = "Your AdMob id";

JarvanZhang 23,971

Try adding a string parameter to the custom InterstitialAd class. To set the adMob id when initializating the class.

public class MyInterstitialAd : InterstitialAd
{
    public string IdValue { get; set; }

    public MyInterstitialAd(string IdValue)
    {
        this.IdValue = IdValue;
    }

    public override string AdUnitId => IdValue;
    ...
}

Answer 2

For a Nov 2021 article, this is useless really.

The Xamarin.GooglePlayServices.Ads for Android has changed dramatically.

        MobileAds.Initialize(this); THIS does not properly load the application Id from the Manifest data AND an overload needs a listener
        MobileAds.Initialize(this, "ca-app-pub-MY APP ID"); THIS is no longer valid and is deprecated

The Manifest needs this:

<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="ca-app-pub-MY APP ID"/>

One needs to add this to the MAinActivity OR into the Renderer

        RequestConfiguration.Builder builder = new RequestConfiguration.Builder();
        builder = builder.SetTestDeviceIds(new string[] { "my device ID" });
        MobileAds.RequestConfiguration = builder.Build();

In a Xamarin.FORMS application, 5 pages, main and 4 child pages... Ads not showing but no errors thrown in code.

I get the following in output, if anyone can enlighten me on this...that would be most helpful!!

[Ads] This request is sent from a test device.
[DynamiteModule] Local module descriptor class for com.google.android.gms.ads.dynamite not found.
[DynamiteModule] Considering local module com.google.android.gms.ads.dynamite:0 and remote module com.google.android.gms.ads.dynamite:214106404
[DynamiteModule] Selected remote version of com.google.android.gms.ads.dynamite, version >= 214106404
[Ads] #4 The webview is destroyed. Ignoring action.

WHAT IS THIS: com.google.android.gms.ads.dynamite?
WHY is this breaking, not being found?

Thanks
