LogoReact Native Google Mobile Ads

Getting Started

The AdMob module allows you to display adverts to your users. All adverts are served over the Google AdMob network, meaning a Google AdMob account is required.

The module supports four types of Ads:

  1. Full screen App Open Ads.
  2. Full screen Interstitial Ads.
  3. Full screen Rewarded Ads.
  4. Component based Banner Ads.

Installation#

On Android, before releasing your app, you must select "Yes, my app contains ads" in the Google Play Console under "Policy and programmes" > "App content" > "Manage".

Optionally configure iOS static frameworks#

Follow these steps on iOS if you need to use static frameworks (that is, use_frameworks! :linkage => :static in your Podfile). You may need this if you use this module in combination with react-native-firebase v15 and higher since it requires use_frameworks!.

Setting up Google AdMob#

Before you are able to display ads to your users, you must have a Google AdMob account. Under the "Apps" menu item, create or choose an existing Android/iOS app. Each app platform exposes a unique account ID which needs to be added to the project.

Attempting to build your app without a valid App ID in app.json will cause the app to crash on start or fail to build.

Under the "App settings" menu item, you can find the "App ID":

Google AdMob App ID

The app IDs for Android and iOS need to be inserted into your apps native code. For React Native projects without Expo, you can add the app IDs to the app.json file. For Expo projects, we provide an Expo config plugin.

Configure outbound requests#

If the default ad settings are not correct for your app, you can provide settings that will apply to all ad requests.

For example, if the application targets children then you must configure the outbound requests to only receive content suitable for children before loading any adverts.

If you need to set a custom request configuration, you must call the setRequestConfiguration method before initializing the Google Mobile Ads SDK:

import mobileAds, { MaxAdContentRating } from 'react-native-google-mobile-ads';

mobileAds()
  .setRequestConfiguration({
    // Update all future requests suitable for parental guidance
    maxAdContentRating: MaxAdContentRating.PG,

    // Indicates that you want your content treated as child-directed for purposes of COPPA.
    tagForChildDirectedTreatment: true,

    // Indicates that you want the ad request to be handled in a
    // manner suitable for users under the age of consent.
    tagForUnderAgeOfConsent: true,

    // An array of test device IDs to allow.
    testDeviceIdentifiers: ['EMULATOR'],
  })
  .then(() => {
    // Request config successfully set!
  });

To learn more about the request configuration settings, view the RequestConfiguration source code.

Initialize the Google Mobile Ads SDK#

Before loading ads, have your app initialize the Google Mobile Ads SDK by calling initialize which initializes the SDK and returns a promise once initialization is complete (or after a 30-second timeout). This needs to be done only once, ideally at app launch.

Ads may be preloaded by the Mobile Ads SDK or mediation partner SDKs upon calling initialize. If you need to obtain consent from users in the European Economic Area (EEA), set any request-specific flags (such as tagForChildDirectedTreatment), or otherwise take action before loading ads, ensure you do so before initializing the Mobile Ads SDK.

import mobileAds from 'react-native-google-mobile-ads';

mobileAds()
  .initialize()
  .then(adapterStatuses => {
    // Initialization complete!
  });

If you are using mediation, you may wish to wait until the promise is settled before loading ads, as this will ensure that all mediation adapters are initialized.

Enable SKAdNetwork to track conversions (iOS)#

The Google Mobile Ads SDK supports conversion tracking using Apple's SKAdNetwork, which lets Google and participating third-party buyers attribute an app install even when the IDFA is not available. Within your projects app.json file, add the advised SKAdNetwork identifiers. Note that these identifiers are subject to change and should be updated regularly.

App Tracking Transparency (iOS)#

Apple requires apps to display the App Tracking Transparency authorization request for accessing the IDFA (leaving the choice to the user, whether to use personalized or non-personalized ads). Within your projects app.json file, you have to provide a user tracking usage description:

Requesting App Tracking Transparency authorization#

To request the App Tracking Transparency authorization we recommend using the react-native-permissions library or making it part of the UMP consent flow European User Consent page.

import { check, request, PERMISSIONS, RESULTS } from 'react-native-permissions';

const result = await check(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY);
if (result === RESULTS.DENIED) {
  // The permission has not been requested, so request it.
  await request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY);
}

const adapterStatuses = await mobileAds().initialize();

// Now ads can be loaded.

European User Consent#

Out of the box, AdMob does not handle any related regulations which you may need to enforce on your application. It is up to the developer to implement and handle this on a user-by-user basis. You must consent to EEA users being served both personalized and non-personalized adverts before showing them. For more information, see Obtaining Consent with the User Messaging Platform.

The AdMob module provides a AdsConsent helper to help developers quickly implement consent flows within their application. See the European User Consent page for full examples of how to integrate the helper into your application.

Test ads#

Whilst developing your app with AdMob, you'll want to make sure you use test ads rather than production ads from your Google AdMob account - otherwise your account may be disabled!

Although usage of different advert types is explained later, when creating your adverts the "Ad Unit ID" being used whilst testing can be set to a testing ID. The code snippet below shows how to initialize each advert type with a test ID:

import { AppOpenAd, InterstitialAd, RewardedAd, BannerAd, TestIds } from 'react-native-google-mobile-ads';

# App Open
AppOpenAd.createForAdRequest(TestIds.APP_OPEN);

# Interstitial
InterstitialAd.createForAdRequest(TestIds.INTERSTITIAL);

# Rewarded
RewardedAd.createForAdRequest(TestIds.REWARDED);

# Banners
<BannerAd unitId={TestIds.BANNER} />

Next Steps#

Now the basics of setting up and configuring AdMob have been explained, we can go ahead and start to display different adverts to our users. The AdMob module provides integration with three different types:
