You can find the Google Ads Mobile integration at /utility/GoogleAds and it is initialized at /app/_layout.js like this:

/app/_layout.js
useEffect(() => {
	mobileAds().initialize()
}, [])

​
Ad Types

ExpoShip Google Ads Mobile integration comes with 4 different ad components.

  • Banner ad
  • Collapsible banner ad
  • Interstitial ad
  • Rewarded interstitial ad

You can implement each of the component by importing it and calling it like this:

example.js
import { View, Text, SafeAreaView, ScrollView, TouchableOpacity } from 'react-native'
import { React, useContext } from 'react'
import { ThemeContext } from '../../utility/ThemeContext'
import AdMobBanner from '../../utility/GoogleAds/AdMobBanner'
import AdMobInterstitial from '../../utility/GoogleAds/AdMobInterstitial'
import AdMobCollapsibleBanner from '../../utility/GoogleAds/AdMobCollapsibleBanner'
import AdMobRewardedInterstitial from '../../utility/GoogleAds/AdMobRewardedInterstitial'
 
export default function Home() {
 
	const { theme } = useContext(ThemeContext)
	const backgroundColor = theme === 'dark' ? 'bg-[--color-primary-default]' : 'bg-[--color-primary-light]';
	const textColor = theme === 'dark' ? 'text-[--color-primary-light]' : 'text-[--color-primary-default]';
 
	return  (
		<SafeAreaView className={`flex-1 ${backgroundColor}`}>
			<Text className={`font-bold text-2xl p-4 text-center mt-6 ${textColor}`}>Google Ads</Text>
 
			<ScrollView className='m-4'>
 
				<View className='mt-8'>
					<AdMobBanner  />
				</View>
 
				<View className='mt-8'>
					<AdMobInterstitial  />
				</View>
 
				<View className='mt-8'>
					<AdMobCollapsibleBanner  />
				</View>
				
				<View className='mt-8'>
					<AdMobRewardedInterstitial  />
				</View>
				
			</ScrollView>
		</SafeAreaView>
	)
}

Configuring Google Ads

You can follow this guide to setup Google Ads in your app - https://docs.page/invertase/react-native-google-mobile-ads.

There are two configuration files /app.json and /.env.local. In /app.json you need to add your ios_app_id and android_app_id like this:

app.json
"react-native-google-mobile-ads": {
	"ios_app_id": "ca-app-pub-3940256099942544~1458002511",
	"android_app_id": "ca-app-pub-3940256099942544~3347511713"
}

By default both app id’s are Google’s test id’s

In /.env.local you need to ad your ad unit id’s like this:

/.env.local
BANNER_AD_UNIT_ID_IOS=ca-app-pub-3940256099942544/9214589741
BANNER_AD_UNIT_ID_ANDROID=ca-app-pub-3940256099942544/9214589741
 
INTERSTITIAL_AD_UNIT_ID_IOS=ca-app-pub-3940256099942544/1033173712
INTERSTITIAL_AD_UNIT_ID_ANDROID=ca-app-pub-3940256099942544/1033173712
 
REWARDED_INTERSTITIAL_AD_UNIT_ID_IOS=ca-app-pub-3940256099942544/5354046379
REWARDED_INTERSTITIAL_AD_UNIT_ID_ANDROID=ca-app-pub-3940256099942544/5354046379

By default all of id’s are Google’s test id’s
