How to use MauiMTAdmob

You can find a tutorial on my blog: https://www.xamarinexpert.it/admob-made-easy/ (Version for Xamarin, I'll update it with the new version for MAUI)

To add a banner in your project

To add a Banner on a page you have two options:

1) XAML

<controls:MTAdView x:Name="myAds"/>

remember to add this line in your XAML:

xmlns:controls="clr-namespace:Plugin.MauiMTAdmob.Controls;assembly=Plugin.MauiMTAdmob"

As you can have different Banner Ids for iOS and for Android, you could use the OnPlatform-Property like this:

<controls:MTAdView x:Name="myAds" AdsId="{OnPlatform Android='ca-app-pub-3940256099942544/6300978111', 
                                   iOS='ca-app-pub-3940256099942544/2934735716'}"/>

Or set it in App.xaml (similar to HeightRequest as explained below) for all banners in your app.

2) Code

MTAdView ads = new MTAdView();

Important

To test the banner during the development google uses two Banner Id, one for Android and the other for iOS. Use them then remember to replace them with your own IDs:

Android: ca-app-pub-3940256099942544/6300978111
iOS: ca-app-pub-3940256099942544/2934735716

Properties

For each AdView if you want, you can set these properties:

AdsId: To add the id of your ads

PersonalizedAds: You can set it to False if you want to use generic ads (for GDPR...) (It works only for Android Banners, for the others, you must ask for consent)

For GDPR it's better to rely on a custom consent instead or using the non personalized ads as I cannot guarantee it works. So it's better if you create a custom consent

Global Properties

AdsId: To add the id of your ads

PersonalizedAds: You can set it to False if you want to use generic ads (for GDPR...) (It works only for Android Banners, for the others, you must ask for consent) For GDPR it's better to rely on a custom consent instead or using the non personalized ads as I cannot guarantee it works. So it's better if you create a custom consent

TestDevices: You can add here the ID of your test devices

You can use Global Properties in this way:

CrossMauiMTAdmob.Current.UserPersonalizedAds = true;

Interstitial

You can show an interstitial with a single line of code:

CrossMauiMTAdmob.Current.ShowInterstitial();

To Load an interstitial you can use this line:

CrossMauiMTAdmob.Current.LoadInterstitial("xx-xxx-xxx-xxxxxxxxxxxxxxxxx/xxxxxxxxxx");

To see if an interstitial is loaded:

CrossMauiMTAdmob.Current.IsInterstitialLoaded();

Rewarded

You can show a Rewarded video with a single line of code:

CrossMauiMTAdmob.Current.ShowRewarded();

To Load a Rewarded Video you can use this line:

CrossMauiMTAdmob.Current.LoadRewarded("xx-xxx-xxx-xxxxxxxxxxxxxxxxx/xxxxxxxxxx");

To see if a rewarded is loaded:

CrossMauiMTAdmob.Current.IsRewardedLoaded();

Rewarded Interstitial

You can show a Rewarded video with a single line of code:

CrossMauiMTAdmob.Current.ShowRewardInterstitial();

To Load a Rewarded Video you can use this line:

CrossMauiMTAdmob.Current.LoadRewardInterstitial("xx-xxx-xxx-xxxxxxxxxxxxxxxxx/xxxxxxxxxx");

To see if a rewarded interstitial is loaded:

CrossMauiMTAdmob.Current.IsRewardInterstitialLoaded();

Important

Remember to include the MTAdmob library with this code (usually it's added automatically):

using Plugin.MauiMTAdmob;

Important for Android

Before loading ads, have your app initialize the Mobile Ads SDK by calling MobileAds.initialize() with your AdMob App ID. This needs to be done only once, ideally at app launch. For example:

 protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
            MobileAds.Initialize(this);
        }

Remember to add this to your AppManifest:

<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID"
           android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>

If your Ads are not displayed on your Android Emulator, make sure your Emulator has Google Play Store API installed, otherwise you'll find this message in your Debugger Console:

[GooglePlayServicesUtil] Google Play Store is missing.

If it's still not showing ads after adding Play Store, open Google Play Store on your emulator. There might be some config work to be done by Play Store, e.g. login with your google account, so just start it and make sure it's working fine on your emulator.

IMPORTANT FOR IOS:

Before loading ads, have your app initialize the Mobile Ads SDK by calling MobileAds.SharedInstance.Start with your AdMob App ID. This needs to be done only once, ideally at app launch. For example:

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
        {
            MobileAds.SharedInstance.Start(CompletionHandler);   <--
            return base.FinishedLaunching(application, launchOptions);
        }

        private void CompletionHandler(InitializationStatus status) { }   <--

Edit your info.plist adding these Keys:

  <key>GADApplicationIdentifier</key>
  <string>ca-app-pub-3940256099942544~1458002511</string> <- This is a test key, replace it with your APPID
  <key>GADIsAdManagerApp</key>
  <true/>

If you are builing your app for iOS on Windows without using your Mac, then MobileAds.SharedInstance will be null and the ads will not work.

You have to build the app using your Mac to use Admob on iOS!

That's it. Cannot be easier than that 😃
