This guide shows you how to use the Google Mobile Ads Flutter Plugin to load and display ads from AppLovin using [mediation](https://developers.google.com/admob/flutter/mediation.md.txt), covering both bidding and waterfall integrations. It covers how to add AppLovin to an ad unit's mediation configuration, and how to integrate the AppLovin SDK and adapter into a Flutter app. ## Supported integrations and ad formats The AdMob mediation adapter for AppLovin has the following capabilities: | Integration || |---|---| | Bidding | Yes | | Waterfall | Yes | | App Open | Yes [^1^](https://developers.google.com/admob/flutter/mediation/applovin.md.txt#app-open-footnote) | | Banner | Yes [^2^](https://developers.google.com/admob/flutter/mediation/applovin.md.txt#banner-footnote) | | Interstitial | Yes | | Rewarded | Yes | | Rewarded Interstitial | | | Native | | ^1^ Waterfall integration is in closed beta. ^2^ Waterfall supports only 320x50 and 728x90 banner sizes. Bidding doesn't support banner ads. ## Prerequisites Before you continue, verify the following: - Latest Google Mobile Ads Flutter Plugin version. - Flutter framework version 3.7.0 or later. - To deploy on Android - Android API level 24 or later. - To deploy on iOS - iOS deployment target of 13.0 or later. - A working Flutter project configured with Google Mobile Ads Flutter Plugin. See [Set up Google Mobile Ads Flutter Plugin](https://developers.google.com/admob/flutter/quick-start.md.txt) for details. - [Set up AdMob Mediation](https://developers.google.com/admob/flutter/mediation.md.txt). ## Step 1: Set up configurations in AppLovin UI - [Sign up](https://dash.applovin.com/signup) or [log in](https://dash.applovin.com/login) to your AppLovin account. - To set up your AdMob ad unit, you'll need your AppLovin **SDK Key** and **Report Key** . To find them, go to the [AppLovin UI](https://dash.applovin.com/login) \> **Account** \> **Keys** to see both values. - ![](https://developers.google.com/static/admob/images/mediation/applovin/keys.png) - If you plan on just integrating bidding, you can proceed to [configure your mediation settings](https://developers.google.com/admob/flutter/mediation/applovin.md.txt#configure-mediation). ### Select app for mediation ### Bidding This step isn't required for bidding integrations. ### Waterfall On the AppLovin UI, select **Applications** under the **Monetization** section to get to your registered apps. Select the app you'd like to use with mediation from the list of available apps. ![](https://developers.google.com/static/admob/images/mediation/applovin/manage_apps_list.png) ### Create a zone ### Bidding This step isn't required for bidding integrations. ### Waterfall On the AppLovin UI, select **Zones** under the **Monetization** section to get to your registered zone IDs. If you have already created the required zones for your app, skip ahead to [Step 2](https://developers.google.com/admob/flutter/mediation/applovin.md.txt#step-2). To create a new zone ID, click **Create Zone**. ![](https://developers.google.com/static/admob/images/mediation/applovin/manage_zones.png) Enter the name of **Zone ID** , select **Android** as the **Platform** , and choose the **Ad Type**. Configure **Pricing** for the zone by selecting either **Flat CPM** or **Optimized by AppLovin** . CPMs can be configured on a per country basis for the **Flat CPM** option. Then, click **Save**. ### Android ![](https://developers.google.com/static/admob/images/mediation/applovin/create_zone_Android.png) ### iOS ![](https://developers.google.com/static/admob/images/mediation/applovin/create_zone_iOS.png) Once the zone is created, the zone ID can be found under the **Zone ID** column. ### Android ![](https://developers.google.com/static/admob/images/mediation/applovin/zone_id_Android.png) ### iOS ![](https://developers.google.com/static/admob/images/mediation/applovin/zone_id_iOS.png) > [!NOTE] > **Note:** We highly recommend that you create an AppLovin zone corresponding to each AdMob ad unit so that AdMob can more effectively [Optimize ad sources in mediation](https://support.google.com/admob/answer/7374110). ### Update your app-ads.txt - [Authorized Sellers for Apps app-ads.txt](https://iabtechlab.com/wp-content/uploads/2019/03/app-ads.txt-v1.0-final-.pdf) is an IAB Tech Lab initiative that helps ensure your app ad inventory is only sold through channels you've identified as authorized. To prevent a significant loss in ad revenue, you'll need to implement an `app-ads.txt` file. If you haven't done so already, [set up an app-ads.txt file for your app](https://support.google.com/admob/answer/9363762). - To implement `app-ads.txt` for AppLovin, [Add AppLovin to your app-ads.txt file](https://developers.applovin.com/en/max/max-dashboard/account/iab-supply-chain-validation#how-to-implement-an-app-adstxt-file). ### Turn on test mode - Follow the instructions in AppLovin's [MAX Test Mode](https://dash.applovin.com/documentation/mediation/ios/testing-networks/test-mode) guide on how to enable AppLovin test ads. ## Step 2: Set up AppLovin demand in AdMob UI ### Configure mediation settings for your ad unit ### Android For instructions, see step 2 in the guide for [Android](https://developers.google.com/admob/android/mediation/applovin.md.txt#step-2). ### iOS For instructions, see step 2 in the guide for [iOS](https://developers.google.com/admob/ios/mediation/applovin.md.txt#step-2). ### Add AppLovin Corp. to GDPR and US state regulations ad partners list > [!IMPORTANT] > **Important:** Verify that you have **Account Management** permission to complete the configuration for EU Consent and GDPR, US State regulations, and User Messaging Platform. See [Manage user access to your > account](https://support.google.com/admob/answer/2784628) for details. - Follow the steps in [European regulations settings](https://support.google.com/admob/answer/10113004#adding_ad_partners_to_published_gdpr_messages) and [US state regulations settings](https://support.google.com/admob/answer/14125907) to add **AppLovin Corp.** to the European and US state regulations ad partners list in the AdMob UI. ## Step 3: Import the AppLovin SDK and adapter > [!NOTE] > **Note:** Failure to integrate the compatible AppLovin and Google Mobile Ads Flutter Plugin versions might lead to build issues. ### Integration through pub.dev - Add the following dependency with the latest versions of the AppLovin SDK and adapter in your package's `pubspec.yaml` file: ```yaml dependencies: gma_mediation_applovin: ^2.6.5 ``` ### Manual Integration - Download the latest version of Google Mobile Ads mediation plugin for [AppLovin](https://pub.dev/packages/gma_mediation_applovin/versions), extract the downloaded file, and add the extracted plugin folder (and its contents) to your Flutter project. Then, reference the plugin in your `pubspec.yaml` file by adding the following dependency: ```yaml dependencies: gma_mediation_applovin: path: path/to/local/package ``` ## Step 4: Implement privacy settings on AppLovin SDK ### EU consent and GDPR - To [comply with the Google EU User Consent Policy](https://www.google.com/about/company/consentstaging.html), you must make certain disclosures to your users in the European Economic Area (EEA), the UK, and Switzerland, and obtain their consent for the use of cookies or other local storage where legally required, and for the collection, sharing, and use of personal data for ads personalization. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). You are responsible for verifying that consent is propagated to each ad source in your mediation chain. - AppLovin Flutter adapter version 1.0.0 and later supports passing GDPR consent signals from [UMP SDK](https://developers.google.com/admob/flutter/privacy.md.txt) and consent management platforms that integrate with [Google's Additional Consent specification](https://support.google.com/admob/answer/9681920) to AppLovin SDK. For more information, see [TCF v2 consent](https://support.applovin.com/en/max/flutter/overview/privacy#tcf-v2-consent). ### Declare child users - AppLovin does not support initialization of the AppLovin SDK in connection with a child. For more information, see AppLovin's documentation on "Prohibition on Children Data or Using the Services for Children or Apps Exclusively Targeted to Children" for [Android](https://developers.applovin.com/en/max/android/overview/privacy#children) or [iOS](https://developers.applovin.com/en/max/ios/overview/privacy#children). - The Google Mobile Ads Flutter mediation plugin for AppLovin version `9.1.0` or higher automatically disables mediation to AppLovin for apps that declare a child user using any of the following settings: - [Set the age treatment](https://developers.google.com/admob/flutter/targeting.md.txt#set_the_age_treatment) - [Child-directed setting](https://developers.google.com/admob/flutter/targeting.md.txt#child-directed_setting) - [Users under the age of consent](https://developers.google.com/admob/flutter/targeting.md.txt#users_under_the_age_of_consent) ### US states privacy laws - [US states privacy laws](https://support.google.com/admob/answer/9561022) require giving users the right to opt out of the "sale" of their "personal information" (as the law defines those terms), with the opt-out offered through a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The [US states privacy laws compliance guide](https://developers.google.com/admob/flutter/privacy/us-states) offers the ability to enable [restricted data processing](https://privacy.google.com/businesses/rdp/) for Google ad serving, but Google is unable to apply this setting to each ad network in your mediation chain. Therefore, you must identify each ad network in your mediation chain that may participate in the sale of personal information and follow guidance from each of those networks to ensure compliance. - The Google Mobile Ads mediation plugin for AppLovin includes the `GmaMediationApplovin.setDoNotSell()` method. The following sample code shows how to pass consent information to the AppLovin SDK. These options must be set before you [initialize the Google Mobile Ads SDK](https://developers.google.com/admob/flutter/quick-start#initialize_the_mobile_ads_sdk) to ensure they get forwarded properly to the AppLovin SDK. ```dart import 'package:gma_mediation_applovin/gma_mediation_applovin.dart'; // ... GmaMediationApplovin.setDoNotSell(true); ``` - See [AppLovin's Privacy documentation](https://dash.applovin.com/documentation/mediation/android/getting-started/privacy#california-consumer-privacy-act-(%E2%80%9Cccpa%E2%80%9D)) for more information. ## Step 5: Add required code ### Android No additional code is required for AppLovin integration. ### iOS ### SKAdNetwork integration Follow [AppLovin's documentation](https://dash.applovin.com/documentation/mediation/ios/getting-started/skadnetwork-info) to add the SKAdNetwork identifiers to your project's Info.plist\` file. ## Step 6: Test your implementation ### Enable test ads - Make sure you [register your test device](https://developers.google.com/admob/flutter/test-ads.md.txt#enable_test_devices) for AdMob and [enable test mode](https://developers.google.com/admob/flutter/mediation/applovin.md.txt#turn-on-test-mode) in AppLovin UI. > [!IMPORTANT] > **Important:** Disable test mode for AdMob and AppLovin before releasing your app. ### Verify test ads - To verify that you are receiving test ads from AppLovin, enable [single ad source testing](https://developers.google.com/admob/flutter/ad-inspector.md.txt#single_ad_source_testing) in ad inspector using the **AppLovin (Bidding) and AppLovin (Waterfall)** ad source(s). ## Optional steps ### Network-specific parameters - The AppLovin adapter supports passing an `AppLovinMediationExtras` object to the ad request to set network-specific parameters. The following sample code shows how to disable audio on video ads using the `isMuted` parameter: ```dart AppLovinMediationExtras applovinExtras = AppLovinMediationExtras(isMuted: true) AdRequest request = AdRequest( keywords: ['foo', 'bar'], contentUrl: 'http://foo.com/bar.html', mediationExtras: [applovinExtras], ); ``` ### Optimizations - Adding a call to `GmaMediationApplovin.initializeSdk('sdkKey')` to your launch activity provides AppLovin the ability to track events as soon as the app starts. ## Error codes - If the adapter fails to receive an ad from AppLovin, publishers can check the underlying error from the ad response using [`ResponseInfo`](https://developers.google.com/admob/flutter/response-info.md.txt) under the following classes: ### Android ```java com.google.ads.mediation.applovin.mediation.ApplovinAdapter com.google.ads.mediation.applovin.AppLovinMediationAdapter ``` ### iOS ```objective-c GADMAdapterAppLovin GADMAdapterAppLovinRewardBasedVideoAd GADMediationAdapterAppLovin ``` - Here are the codes and accompanying messages thrown by the AppLovin adapter when an ad fails to load: ### Android | Error code | Reason | |---|---| | -1009 to -1, 204 | AppLovin SDK returned an error. See [AppLovin's documentation](https://dash.applovin.com/docs/integration#androidErrors) for more details. | | 101 | The requested ad size does not match an AppLovin supported banner size. | | 103 | Context is null. | | 104 | AppLovin bid token is empty. | | 105 | Requested multiple ads for the same zone.
