This guide instructs you step-by-step on how to set Google as a bidder network on Unity LevelPlay Mediation.

Prerequisites

Ensure that you have correctly integrated ironSource SDK  interstitial, rewarded video or banner mediation in your application. Google Ad Manager ads are served using the AdMob SDK.

Google bidding is supported starting from ironSourcr SDK version 7.2.7+.

Step 1. Create an AdMob Account

  1. To access Google's ad inventory through Unity LevelPlay Mediation, you need to create an account with AdMob.
  2. It's recommended to adjust the time zone of your AdMob account to UTC to align with the Unity LevelPlay platform. This will ensure accurate reporting. Learn more.

Step 2. Create an application and ad unit in AdMob

Next, you must add your app to your AdMob account.

Add Your App

  • Log into your AdMob account. On your dashboard, click Apps then Add app.
  • A modal will appear where you can either search for your app, add your app manually or simply select an existing app to monetize. You'll need a unique AdMob application per platform (iOS + Android), similar to your ironSource account.
  • Select interstitial, rewarded video, or banners as your ad unit format and enter the relevant details.
  • Interstitial
    • Ad unit name: Name the ad unit intuitively so it will be easy to recognize as the ad unit you'll be serving
    • Partner bidding: Check the box to indicate that you are using bidding on another mediation platform
  • Rewarded Video
    • Ad unit name: Name the ad unit intuitively so it will be easy to recognize as the ad unit you'll be serving
    • Partner bidding: Check the box to indicate that you are using bidding on another mediation platform
  •  Banners
    • Ad unit name: Name the ad unit intuitively so it will be easy to recognize as the ad unit you'll be serving
    • Partner bidding: Check the box to indicate that you are using bidding on another mediation platform

Step 3. Activate Google in your LevelPlay network setup module

There are two ways that you can get Meta Audience Network setup on LevelPlay:

  • Auto-setup - Login with your Google account to automatically create new application and bidding placements and pull all the necessary configurations settings from Google AdMob platform
  • Manual - Go between the LevelPlay and Google AdMob platforms to retrieve and enter the necessary information.

Auto-setup

  • Log into your LevelPlay account and go to the LevelPlay side nav bar > SetupNetworks
  • Select Google AdMob from the list of available ad networks
  • Click Login with Google and log in with your approved Google account
  • If you’re already logged in, click reset login (A new log-in is required)
  • After you’re logged in, toggle on Google auto-setup bidder
  • Now go to the Instances page, and select the app where you’d like to run interstitial, rewarded, or banner ads from Google. 
  • Click the Add Bidder button to automatically create new apps and bidding placements on the AdMob platform, and import the Ad Unit ID. If there is an App ID already attached to the app, you will be able to use the auto-setup tool if there is at least 1 placement without the Ad unit ID parameter value. In this case, a new bidding placement will be created.
  • Click Save to approve and accept all configurations. If you close the module without saving, the assets will be created on the AdMob platform without importing the data onto the LevelPlay platform.

The status of Google bidder instances will be the same as the status of the ironSource Ads bidder, by ad format. For example, if you’re not using the ironSource Ads bidder for rewarded videos, it will not be automatically activated for the Google network.

Manual Setup

  • Log into your LevelPlay account and go to the LevelPlay side nav bar > SetupNetworks
  • Select Google AdMob from the list of available ad networks

There are a few pieces of data from your AdMob account that need to be inserted into your LevelPlay Network Setup Module in order for AdMob to work correctly with the ironSource SDK:

App IDThe unique ID assigned to your app on Admob's dashboard.
Ad Unit IDThe unique ID assigned to your app's ad unit on Admob's dashboard.
Client IDThis is the unique identifier that specifies the relationship between your account and the ad unit.
Client SecretThe secret key that pairs with the Client ID
Refresh TokenThis is the refresh token the client application already received.

After you obtain this information, you must configure AdMob's Parameters into LevelPlay.

      1. App ID To retrieve your App ID, go to 'Apps' tab on the left side bar on Admob's platform and click on 'App Settings' .  You will then see the application's settings, as well as the App ID. 2. Ad Unit ID To retrieve your Ad Unit ID, go to 'Apps' tab on the left side bar on Admob's platform and click on 'Ad Units'. You will then see the application's ad units, as well as the Ad Unit ID. 3. Client ID  and Client Secret
        1. To retrieve your Client ID & Client Secret, go to Google's API Manager.
        2. Click on the API Project drop-down at the upper-left of the page, select 'Create a project' or select the project you already created for this app. In the case you are creating a new project for this purpose,  provide a Project name, Billing account, and Location in the dialog box that appears and click Create.
        3. In the left sidebar, select Credentials, then select the OAuth consent screen tab.Then, provide a Product Name and click Save.
        4. In the left sidebar, select Dashboard**,** and go to Enable APIs and services.
        5. Next, enable the AdMob API.
        6. Select the Credentials tab in the left sidebar. Click the Create Credentials drop-down and select OAuth client ID.
        7. Select Web application, and provide a name for your app. In the fields below, you must enter https://developers.google.com/oauthplayground for at least one Authorized redirect URI. For example:
        8. Click Create, and you will be presented with your Client ID and Client Secret.
        9. Refresh Token
          1. To retrieve your Refresh Token, go to the OAuth 2.0 Playground.
          2. Click the settings icon in the upper right corner. Uncheck the box labeled Force approval prompt and check Use your own OAuth credentials. Input your Client ID and Client Secret.
          3. Next, in Step 1: Select & Authorize APIS, enter 'https://www.googleapis.com/auth/admob.report' and click Authorize APIs.
          4. Grant your project access to your AdMob data
          5. You should then receive the Authorization Code from Step 1 and will be able to click the Exchange authorization code for tokens button. Then you will get a Refresh token as well as an Access Token.
  • After you have all of these parameters, enter them into the Google AdMob account settings on LevelPlay.

  • Next, go to the Instances page. Select the app at the top of the page for which you’d like to run Unity LevelPlay's Mediation with Google bidding.

  • Select Google from the setup list of Ad Networks and click on the tool Define icon. Then insert the App ID and Ad Unit ID  under Interstitial, Rewarded Video or Banner Settings.

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.

  1. Make sure you have the following lines inside  allprojects->repositories block

    allprojects {
        repositories {
           flatDir {
               dirs 'libs'
           }
           google()
        }
    }
    
  2. 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:

  1. 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()
        mavenCentral()
    }
    
    
  2. Add the adapter's Maven name to your build.gradle script of your app module:

    dependencies {
    implementation 'com.unity3d.ads-mediation:admob-adapter:4.3.53'
    implementation 'com.google.android.gms:play-services-ads:24.5.0'
    }
    

To integrate the Admob Adapter through Manual Download:

      1. 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. 2. 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. 3. Make sure you add the following to your Gradle build file under the dependencies section:
            dependencies {
            implementation 'com.unity3d.ads-mediation:admob-adapter:4.3.52'
            implementation 'com.google.android.gms:play-services-ads:24.4.0'
            }
        

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. If you intend to keep your Jar integration, 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, refer to AdMob's guide.

Step 6. Additional Steps
