Tutorial Expo React Native Google AdMob

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.

First steps

Installation

# Install the admob module and config plugin

npx expo install react-native-google-mobile-ads

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!.

Expo users may enable static frameworks by using the expo-build-properties plugin. To do so follow the official expo-build-properties installation instructions and merge the following code into your app.json, app.config.js, or app.config.ts file:

// <project-root>/app.json

{

"expo": {

"plugins": [

[

"expo-build-properties",

{

"ios": {

"useFrameworks": "static"

}

]

}

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 configuring a valid App ID for this package will cause the app to crash on start or fail to build.

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

The app IDs for Android and iOS need to be inserted into your app's native code. For bare React Native projects, you can add the app IDs to the app.json file. For Expo projects, we provide an Expo config plugin.

This library contains an Expo config plugin which you must add to your app.json, app.config.js, or app.config.ts file. For these changes to take effect, you must rebuild your project's native code and install the new build on your device.

// <project-root>/app.json
{
"expo": {
"plugins": [
[
"react-native-google-mobile-ads",
{
"androidAppId": "ca-app-pub-xxxxxxxx~xxxxxxxx",
"iosAppId": "ca-app-pub-xxxxxxxx~xxxxxxxx"
}
]
]
}
}

This module contains custom native code which is NOT supported by Expo Go

If you're using Expo without EAS, run the following commands:

# For iOS

npx expo prebuild

npx expo run:ios

# For Android

npx expo prebuild

npx expo run:android

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!

});

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. Add the advised SKAdNetwork identifiers to your project as described below. Note that these identifiers are subject to change and should be updated regularly.

// <project-root>/app.json

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 configuration file, you have to provide a user tracking usage description:

// <project-root>/app.json

{

"expo": {

"plugins": [

[

"react-native-google-mobile-ads",

{

"androidAppId": "ca-app-pub-xxxxxxxx~xxxxxxxx",

"iosAppId": "ca-app-pub-xxxxxxxx~xxxxxxxx",

"userTrackingUsageDescription": "This identifier will be used to deliver personalized ads to you."

}

]

}

Requesting App Tracking Transparency authorization

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

import {

getTrackingPermissionsAsync,

PermissionStatus,

requestTrackingPermissionsAsync,

} from 'expo-tracking-transparency';

const { status } = await getTrackingPermissionsAsync();

if (status === PermissionStatus.UNDETERMINED) {

await requestTrackingPermissionsAsync();

}

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.
