Google AdMob plugin for .NET MAUI

Monetize your .NET MAUI app with Google AdMob ads on Android and iOS — banner, interstitial, rewarded, rewarded interstitial, app open, and native ads (including native video) — with GDPR consent handled for you via Google's User Messaging Platform (UMP). Free and open source, with every feature included.

dotnet add package Plugin.AdMob

Why Plugin.AdMob?

• Every AdMob ad format — banners in all sizes (including custom), full-screen interstitial, rewarded, and rewarded interstitial ads, app open ads, and fully customizable native ads with video playback.
• Free and open source — MIT-licensed, no paid tiers, no locked features.
• Consent built in — the Google UMP consent form (GDPR) is shown automatically on startup when required, or take full control yourself via IAdConsentService.
• MAUI-first API — drop a BannerAd or NativeAdView into your XAML, and use dependency-injected services (IInterstitialAdService, IRewardedAdService, IAppOpenAdService, ...) for full-screen ads.
• Test ads out of the box — set AdConfig.UseTestAdUnitIds = true and develop safely against Google's test ad units.
• Cross-platform friendly — your app still compiles and runs on Windows and Mac Catalyst; ads are simply not shown there.
• Actively maintained — built for .NET 10 and the latest .NET MAUI, on top of up-to-date Google Mobile Ads SDK bindings.

Quick start

1. Install the package:

dotnet add package Plugin.AdMob

2. Initialize the plugin in your MauiProgram.cs:

builder
    .UseMauiApp<App>()
    .UseAdMob();

Then complete the one-time platform configuration (Android manifest, iOS Info.plist) described in the Setup guide.

3. Show a banner ad by dropping the control into any page:

<ContentPage xmlns:admob="clr-namespace:Plugin.AdMob;assembly=Plugin.AdMob"
             ...>

    <admob:BannerAd AdUnitId="ca-app-pub-xxxxxxxxxxxxxxxx/xxxxxxxxxx" />

</ContentPage>

4. Show an interstitial ad:

var interstitialAdService = IPlatformApplication.Current.Services.GetRequiredService<IInterstitialAdService>();
interstitialAdService.PrepareAd();
// Once loaded (OnAdLoaded), e.g. between levels:
interstitialAdService.ShowAd();

Tip: no ad unit IDs yet? Set AdConfig.UseTestAdUnitIds = true to use Google's test ads while developing.
