Then, navigate to the **Unity Ads Monetization** \> **Organization Settings** and take note of the **Organization core ID**.  ### 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 Unity Ads, see [setting up app-ads.txt for the first time](https://docs.unity.com/grow/en-us/ads/optimization/app-ads-txt#setting-up-app-adstxt-for-the-first-time). ### Turn on test mode Test mode can be enabled from the [Unity Ads dashboard](https://cloud.unity.com/home/). Navigate to **Unity Ads Monetization** \> **Testing**. You can force test mode for your app by clicking the edit button beside **Google Play Store** , enabling **Override client test mode** and selecting **Force test mode ON (i.e. use test ads) for all devices**.  Alternatively, you can enable test mode for specific devices by clicking **Add Test Device**.  Enter your test device details, then click **Save**.  ## Step 2: Set up Unity Ads demand in AdMob UI ### Configure mediation settings for your ad unit You need to add Unity Ads to the mediation configuration for your ad unit. First, sign in to your [AdMob account](https://apps.admob.com/). Next, navigate to the **Mediation** tab. If you have an existing mediation group you'd like to modify, click the name of that mediation group to edit it, and skip ahead to [Add Unity Ads as an ad source](https://developers.google.com/admob/android/next-gen/mediation/unity.md.txt#add-ad-source). To create a new mediation group, select **Create Mediation Group**.  Enter your ad format and platform, then click **Continue**.  Give your mediation group a name, and select locations to target. Next, set the mediation group status to **Enabled** , and then click **Add Ad Units**.  Associate this mediation group with one or more of your existing AdMob ad units. Then click **Done**.  You should now see the ad units card populated with the ad units you selected:  ### Add Unity Ads as an ad source ### Bidding
In the **Ad Sources** section, find the **Bidding** card and select **Add ad source** . Then select **Unity Ads** . Click **How to sign a partnership agreement** and [set up a bidding partnership](https://support.google.com/admob/answer/9842838) with Unity Ads.  Click **Acknowledge \& agree** , then click **Continue** .  If you already have a mapping for Unity Ads, you can select it. Otherwise, click **Add mapping** .  Next, enter the **Game ID** and **Placement ID** obtained in the previous section. Then click **Done** . **Important** : The **Game ID** must be associated with the targeted app as in the Unity Ads UI.  ### Waterfall
Under the **Waterfall** card in the **Ad Sources** section, select **Add Ad Source** . Select **Unity Ads** and enable the **Optimize** switch. Enter the **API Key** and **Organization core ID** obtained in the previous section to set up ad source optimization for Unity Ads. Then enter an **eCPM value** for Unity Ads and click **Continue** .  > [!NOTE] > **Note**: You only need to set up ad source optimization once per network.
If you already have a mapping for Unity Ads, you can select it. Otherwise, click **Add mapping** .  Next, enter the **Game ID** and **Placement ID** obtained in the previous section. Then click **Done** . **Important** : The **Game ID** must be associated with the targeted app as in the Unity Ads UI.  > [!NOTE] > **Note** : Ad source optimization takes a few days to gather enough data to accurately calculate eCPM for a mediation network. In the meantime, the ad source optimization status is `PENDING`, so you must manually set an eCPM value for the network. Once the eCPM can be calculated, the ad source automatically starts updating the eCPM on your behalf. ### Add Unity Ads 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 **Unity Ads** to the European and US state regulations ad partners list in the AdMob UI. ## Step 3: Import the Unity Ads SDK and adapter > [!NOTE] > **Note:** Failure to integrate the compatible Unity Ads and GMA Next-Gen SDK versions might lead to build issues. ### Android Studio integration (recommended) In your app-level gradle file, add the following implementation dependencies and configurations: ### Kotlin ```kotlin dependencies { implementation("com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk:1.6.0") implementation("com.unity3d.ads:unity-ads:4.21.0") implementation("com.google.ads.mediation:unity:4.21.0.0") } configurations.configureEach { exclude(group = "com.google.android.gms", module = "play-services-ads") exclude(group = "com.google.android.gms", module = "play-services-ads-lite") } ``` ### Groovy ```groovy dependencies { implementation 'com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk:1.6.0' implementation 'com.unity3d.ads:unity-ads:4.21.0' implementation 'com.google.ads.mediation:unity:4.21.0.0' } configurations.configureEach { exclude group: 'com.google.android.gms', module: 'play-services-ads' exclude group: 'com.google.android.gms', module: 'play-services-ads-lite' } ``` ### Manual integration 1. Download the latest Unity Ads SDK (`unity-ads.aar`) from their [GitHub repository](https://github.com/Unity-Technologies/unity-ads-android/releases) and add it to your project. 2. Navigate to the [Unity Ads adapter artifacts](https://maven.google.com/web/index.html#com.google.ads.mediation:unity) on Google's Maven Repository. Select the latest version, download the Unity Ads adapter's `.aar` file, and add it to your project. ## Step 4: Implement privacy settings on Unity Ads 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. Unity Ads Android adapter version 4.19.0.1 and later supports passing GDPR consent signals from consent management platforms that integrate with IAB's Transparency and Consent Framework (TCF) to Unity Ads SDK. For more information, see [Set up a TCF or non-TCF consent configuration](https://docs.unity.com/en-us/grow/ads/privacy/gdpr/tcf-and-non-tcf-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/android/next-gen/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. In SDK version 2.0.0, Unity Ads added an API to support privacy settings. The following sample code shows how to pass this consent information to the Unity Ads SDK. Should you choose to pass consent information to the Unity Ads SDK manually, it is recommended that this code is called prior to requesting ads through GMA Next-Gen SDK. ### Java ```java MetaData ccpaMetaData = new MetaData(this); ccpaMetaData.set("privacy.consent", true); ccpaMetaData.commit(); ``` ### Kotlin ```kotlin val ccpaMetaData = MetaData(this) ccpaMetaData["privacy.consent"] = true ccpaMetaData.commit() ``` See Unity Ads' [Consumer privacy act compliance](https://docs.unity.com/en-us/grow/ads/privacy/ccpa-compliance) for more details and the values that can be provided in each method. ### Set age treatment Unity Ads mediation adapter version 4.16.6.0 and later forwards the [child-directed setting](https://developers.google.com/admob/android/next-gen/targeting.md.txt#child-directed_setting) and [users under the age of consent](https://developers.google.com/admob/android/next-gen/targeting#users_under_the_age_of_consent) setting to Unity Ads. To process these signals on a per-user basis, Unity Ads requires you to enable the **Mixed Audience** designation in the Unity Monetization dashboard. For more information about enabling a mixed audience designation on your project, see [Setting game-level age designations](https://docs.unity.com/en-us/grow/ads/privacy/coppa-compliance#setting-game-level-age-designations). ## Step 5: Add required code #### Load ad with Activity context Pass `Activity` context when loading Banner, Interstitial and Native ad formats. Without activity context, ad load will fail. ## Step 6: Test your implementation ### Enable test ads Make sure you [register your test device](https://developers.google.com/admob/android/next-gen/test-ads.md.txt#enable_test_devices) for AdMob and [enable test mode](https://developers.google.com/admob/android/next-gen/mediation/unity.md.txt#turn-on-test-mode) in Unity Ads UI. > [!IMPORTANT] > **Important:** Disable test mode for AdMob and Unity Ads before releasing your app. ### Verify test ads To verify that you are receiving test ads from Unity Ads, enable [single ad source testing](https://developers.google.com/admob/android/next-gen/ad-inspector.md.txt#single_ad_source_testing) in ad inspector using the **Unity Ads (Bidding) and Unity Ads (Waterfall)** ad source(s). ## Error codes If the adapter fails to receive an ad from Unity Ads, publishers can check the underlying error from the ad response using [`ResponseInfo.getAdSourceResponses()`](https://developers.google.com/admob/android/next-gen/reference/com/google/android/libraries/ads/mobile/sdk/common/ResponseInfo.md.txt#getAdSourceResponses()) under the following classes: ```java com.google.ads.mediation.unity.UnityAdapter com.google.ads.mediation.unity.UnityMediationAdapter ``` Here are the codes and accompanying messages thrown by the UnityAds adapter when an ad fails to load: | Error code | Reason | |---|---| | 0-10 | UnityAds SDK returned an error. See [code](https://github.com/googleads/googleads-mobile-android-mediation/blob/master/ThirdPartyAdapters/unity/unity/src/main/java/com/google/ads/mediation/unity/UnityAdsAdapterUtils.java#L94-L127) for more details. | | 101 | UnityAds server parameters configured in the AdMob UI are missing/invalid. | | 102 | UnityAds returned a placement with a NO_FILL state. | | 103 | UnityAds returned a placement with a DISABLED state. | | 104 | UnityAds tried to show an ad with a null context. | | 105 | Context used to initialize, load and/or show ads from Unity Ads is not an Activity instance. | | 106 | UnityAds tried to show an ad that's not ready to be shown. | | 107 | UnityAds is not supported on the device. | | 108 | UnityAds can only load 1 ad per placement at a time. | | 109 | UnityAds finished with an ERROR state. | | 110 | The requested ad size does not match a UnityAds supported banner size. | | 111 | UnityAds returned an initialization error. | | 112 | Unity Ads returned a null or empty bidding token. | | 200-204 | UnityAds Banner specific error. See [code](https://github.com/googleads/googleads-mobile-android-mediation/blob/b1a70fcab0e7891efacffdff523d86573e2286c7/ThirdPartyAdapters/unity/unity/src/main/java/com/google/ads/mediation/unity/UnityAdsAdapterUtils.java#L69-L84) for more details. | ## Unity Ads Android Mediation Adapter Changelog #### Next Version - Added `UnityMediationAdapter.setTestMode()` and `UnityMediationAdapter.isTestMode()` to allow enabling test mode on the Unity Ads SDK. - Updated the adapter to use the `InitializationCompleteCallback.onInitializationFailed(AdError)` API. #### Version 4.21.0.0 - Verified compatibility with Unity Ads SDK 4.21.0.
