Xamarin.Forms add Google AdMob integration

Issue

I have in the past successfully implement the Google AdMob, but this time with a new project, it's impossible!

I have error with Google AdMob integration in a blank Xamarin.Forms project.

In the standard project :

Have theres Nuget packages already installed :

• NETStandard.Library 2.0.3
• Xamarin.Essentials 1.3.1
• Xamarin.Forms 4.4.0.991265

Create AdmobControl class In the MainPage.xaml.cs add the AdmobControl with the banner ad id for Android TEST : "ca-app-pub-3940256099942544/6300978111"

In the Android project :

Have theres Nuget packages already installed :

• Xamarin.Essentials 1.3.1
• Xamarin.Forms 4.4.0.991265

Then install the Nuget package Xamarin.Firebase.Ads 71.1601.0

In the MainActivity, inititialize Ads before Xamarin.Forms.Init, with App id for Android TEST : "" -> empty string

Add ACCESS_NETWORK_STATE permission

Add INTERNET permission

Add the line in the AndroidManifest.xml between the tag

Create AdMobRenderer class

The problem :

The compilation is ok BUT, when I deploy on app on my device, I have 2 errors : error: MediationRewardedVideoAdListenerImplementor is not abstract and does not override abstract method zzc(Bundle) in MediationRewardedVideoAdListener public class MediationRewardedVideoAdListenerImplementor TestAdMob.Android C:\Users\TheFloods\source\repos\TestAdMob\TestAdMob\TestAdMob.Android\obj\Debug\90\android\src\mono\com\google\android\gms\ads\reward\mediation\MediationRewardedVideoAdListenerImplementor.java 4

Solution

Thank you for your help you two. I have solved the problem like this :

1. Uninstall the Xamarin.Firebase.Ads
2. Install the Xamarin.Firebase.Ads.Lite
3. Add the app ip in the AndroidManifest.xml, after the activity tag
4. Install the Xamarin.GooglePlayServices.Ads.Lite, then it works!
