Google AdMob Integration Guide
This guide instructs you step-by-step on how to set AdMob and AdMob Native as live ad networks on Unity LevelPlay Mediation.
Google Ad Manager ads are served using the AdMob SDK.
Step 1. Create an AdMob Account
- To access AdMob’s banner and native ad inventory through Unity LevelPlay Mediation, you need to create an account with AdMob.
- It’s recommended to adjust the time zone of your AdMob account to UTC to align with the ironSource platform. This will ensure accurate reporting. Learn more.
Step 2. Create an Application and Ad Zone in Admob
Next, you must add your app and set up Ad Zones in your AdMob account.
AdMob does not allow setting up more than 3 ad zones of the same Ad Type in the same setup.
e.g. no more than three Rewarded Video ads are allowed for the mediation group.
Add Your App
- Log into your AdMob account. On your dashboard, click Apps.
- A modal will appear where you can either search for your app, add your app manually or simply select an existing app to monetize.
Note: You’ll need a unique AdMob application per platform (iOS + Android), just like your ironSource account. - Select interstitial, rewarded video, banners, or native advanced (native ads for banners) as your ad unit format and enter the relevant details.
- Interstitial
- Rewarded Video
- Banners
- Ad Unit Name: we recommend naming the ad unit intuitively so it will be easy to recognize as the ad unit you’ll be serving AdMob Banners Unity LevelPlay Mediation
- eCPM floor – Enable and enter an eCPM value according to your country and waterfall strategy
Automatic refresh: Select the “Do not refresh” option. (Reminder – you can control the refresh rate on the mediation platform)
- Native Banners
Native ads for banners enables you to access native ad demand from Google AdMob. This means that you can increase banner performance by accessing both Google’s native and banner demand.
-
- Ad unit name: Type a name that you are going to easily recognize
- Advanced settings: Select both Image and Video
- eCPM floor – Enable and enter an eCPM value according to your country and waterfall strategy
Now retrieve your App ID and Ad Unit ID and save them for later use. Then, click Done.
Step 3. Activate AdMob in Your ironSource Network Setup Module
Sign in to your Google account when setting up AdMob on the ironSource SDK Networks Setup page and the necessary parameters to run AdMob interstitials, rewarded video, banners, and native ads will automatically be retrieved.
There are a few pieces of data from your AdMob account which need to be inserted into your ironSource Network Setup Module in order for AdMob to work correctly with the ironSource SDK:
App ID |
The unique ID assigned to your app on Admob’s dashboard.
|
Ad Unit ID |
The unique ID assigned to your app’s ad unit on Admob’s dashboard.
|
Client ID |
This is the unique identifier that specifies the relationship between your account and the ad unit.
|
Client Secret |
The secret key that pairs with the Client ID
|
Refresh Token |
This is the refresh token the client application already received.
|
Once you obtain this information, you must configure AdMob’s Parameters in your ironSource Account. By adding the above information correctly, you will be able to take full advantage of AdMob’s ad inventory and reporting data on Unity LevelPlay Mediation.

Step 4. Add the Admob Adapter to Your Build
As of V17.0.0 (Adapter version 4.3.1 onwards), AdMob’s SDK requires publishers to add their AdMob App ID to the app’s AndroidManifest as a child of the <application/>
tag:
<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="[ADMOB_APP_ID]"/>
Replace the “[ADMOB_APP_ID]” with the APP ID value you retrieve in step 3.
- Make sure you have the following lines inside allprojects->repositories block
allprojects { repositories { flatDir { dirs 'libs' } google() } }
- Add the following dependency into the dependencies block
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) }
Android
ironSource SDK supports both Gradle dependencies and manual download mechanisms.
To integrate the Admob Adapter with Gradle:
-
-
- Make sure the following Maven URL exist in your build.gradle script of your app module (should appear only once for all the adapters).
repositories { google() maven { url "https://android-sdk.is.com/" } }
- Add the adapter’s Maven name to your build.gradle script of your app module:
implementation 'com.google.android.gms:play-services-ads:23.4.0' implementation 'com.ironsource.adapters:admobadapter:4.3.46'
- Make sure the following Maven URL exist in your build.gradle script of your app module (should appear only once for all the adapters).
-
To integrate the Admob Adapter through Manual Download:
-
-
- Download the Admob Adapter:
Add the Admob Adapter to your build. You can find the latest Admob Adapter here.
Important! The Admob Adapter Does not contain the Admob SDK. You need to additionally add the Admob SDK directly. - Add the Admob Adapter to your Project:
After you download the Adapter; drop the Admob Adapter jar into the libs folder in your Android Project.
- Make sure you add the following to your Gradle build file under the dependencies section:
implementation 'com.google.android.gms:play-services-ads:23.4.0' implementation 'com.ironsource.adapters:admobadapter:4.3.46'
- Download the Admob Adapter:
-
Step 5. Update AndroidManifest.xml
As of ironSource Android SDK Version 6.17.0 (AdMov Android adapter version 4.3.10+), AdMob adapter will be released as AAR. Only if you intend to keep your Jar integration, please add the manifest.
Manifest Permissions:
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Manifest Activities:
Add the following activities inside the <application> tag on your manifestAdditions:
<activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" android:theme="@android:style/Theme.Translucent" />
As of V17.0.0 (Adapter version 4.3.1 onwards), AdMob’s SDK requires publishers to add their AdMob App ID to the app’s AndroidManifest as a child of the <application></application>
tag:
<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="[ADMOB_APP_ID]"/>
Replace the “[ADMOB_APP_ID]” with the APP ID value you retrieved in step 3.
Not doing so results in crashes originated with AdMob’s SDK. For more information please refer to AdMob’s guide.
