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 **Moloco Ads** to the European and US state regulations ad partners list in the AdMob UI. ## Step 3: Import the Moloco SDK and adapter > [!NOTE] > **Note:** Failure to integrate the compatible Moloco and Google Mobile Ads SDK (Legacy) versions might lead to build issues. ### Android Studio integration (recommended) In your app-level `build.gradle.kts` file, add the following implementation dependencies and configurations. Use the latest versions of the Moloco SDK and adapter: ```kotlin dependencies { implementation("com.google.android.gms:play-services-ads:25.5.0") implementation("com.google.ads.mediation:moloco:4.14.0.0") } ``` ## Step 4: Implement privacy settings on Moloco 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. Moloco Ads SDK Android adapter version 3.5.0.0 and later supports passing GDPR consent signals from consent management platforms that integrate with IAB's Transparency and Consent Framework (TCF) to Moloco Ads SDK SDK. For more information, see [`MolocoPrivacy` documentation](https://moloco.github.io/android-sdk-docs/-moloco%20-s-d-k%20-android/com.moloco.sdk.publisher.privacy/-moloco-privacy). ### 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/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 Moloco SDK includes the `isDoNotSell` flag to pass consent information to the Moloco SDK. The following sample code shows how to pass consent information to the Moloco SDK. If you choose to set these flags, it is recommended that you do so prior to requesting ads through Google Mobile Ads SDK (Legacy). ### Kotlin ```kotlin val privacySettings = PrivacySettings(isDoNotSell = true) MolocoPrivacy.setPrivacy(privacySettings) ``` ### Java ```java PrivacySettings privacySettings = new PrivacySettings( /* isUserConsent= */ false, /* isAgeRestrictedUser= */ false, /* isDoNotSell= */ true); MolocoPrivacy.setPrivacy(privacySettings); ``` See [Moloco SDK Android documentation](https://moloco.github.io/android-sdk-docs) for more information. ## Step 5: Test your implementation ### Enable test ads Make sure you [register your test device](https://developers.google.com/admob/android/test-ads.md.txt#enable_test_devices) for AdMob. > [!IMPORTANT] > **Important:** Disable test mode for AdMob and Moloco Ads SDK before releasing your app. ### Verify test ads To verify that you are receiving test ads from Moloco Ads SDK, enable [single ad source testing](https://developers.google.com/admob/android/ad-inspector.md.txt#single_ad_source_testing) in ad inspector using the **Moloco (Bidding)** ad source(s). ## Error codes If the adapter fails to receive an ad from Moloco, you can check the underlying error from the ad response using [`ResponseInfo.getAdapterResponses()`](https://developers.google.com/admob/android/reference/com/google/android/gms/ads/ResponseInfo.md.txt#getAdapterResponses()) under the following classes: ```java com.moloco.sdk com.google.ads.mediation.moloco.MolocoMediationAdapter ``` Here are the codes and accompanying messages thrown by the Moloco adapter when an ad fails to load: | Error code | Domain | Reason | |---|---|---| | 101 | com.google.ads.mediation.moloco | Missing or invalid Moloco App Key. | | 102 | com.google.ads.mediation.moloco | Missing or invalid Moloco Ad unit ID. | | 103 | com.google.ads.mediation.moloco | Moloco ad object returned was null. | | -1 to 5000 | com.moloco.sdk | Moloco SDK returned an error. See Moloco's [documentation](https://moloco.github.io/android-sdk-docs/-moloco%20-s-d-k%20-android/com.moloco.sdk.publisher/-moloco-ad-error/-error-type/#entries) for more details. | ## Moloco Android Mediation Adapter Changelog #### Version 4.14.1.0 (In progress) - Updated how the Google Mobile Ads SDK `tagForUnderAgeOfConsent` and `tagForChildDirectedTreatment` parameters are forwarded to the Moloco SDK. #### Version 4.14.0.0 - Verified compatibility with Moloco SDK 4.14.0.
