Add Unity Ads to GDPR and US state regulations ad partners list

GDPR 設定 米国の州規制の設定 の手順に沿って、 Ad Manager UI の GDPR および米国の州規制の広告パートナーのリストに Unity Ads を追加します。

Step 3: Import the Unity Ads SDK and adapter

In your app-level build.gradle.kts file, add the following implementation dependencies and configurations. Use the latest versions of the Unity Ads SDK and adapter:

dependencies {
    implementation("com.google.android.gms:play-services-ads:23.3.0")
    implementation("com.unity3d.ads:unity-ads:4.12.1")
    implementation("com.google.ads.mediation:unity:4.12.2.0")
}

Manual integration

  1. Download the latest Unity Ads SDK (unity-ads.aar) from their GitHub repository and add it to your project.

  2. Navigate to the Unity Ads adapter artifacts 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

Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.

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 the Google Mobile Ads SDK.

Java

import com.unity3d.ads.metadata.MetaData;
// ...

MetaData gdprMetaData = new MetaData(this);
gdprMetaData.set("gdpr.consent", true);
gdprMetaData.commit();

Kotlin

import com.unity3d.ads.metadata.MetaData
// ...

val gdprMetaData = MetaData(this)
gdprMetaData["gdpr.consent"] = true
gdprMetaData.commit()

See Unity Ads' Privacy Consent and data APIs and Complying with GDPR guides for more details and the values that can be provided in each method.

US states privacy laws

U.S. states privacy laws 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 via a prominent "Do Not Sell My Personal Information" link on the "selling" party's homepage. The U.S. states privacy laws compliance guide offers the ability to enable restricted data processing 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 the Google Mobile Ads SDK.

Java

import com.unity3d.ads.metadata.MetaData;
// ...

MetaData ccpaMetaData = new MetaData(this);
ccpaMetaData.set("privacy.consent", true);
ccpaMetaData.commit();

Kotlin

import com.unity3d.ads.metadata.MetaData
// ...

val ccpaMetaData = MetaData(this)
ccpaMetaData["privacy.consent"] = true
ccpaMetaData.commit()

See Unity Ads' Privacy Consent and data APIs and Complying with CCPA guides for more details and the values that can be provided in each method.

Step 5: Add required code

No additional code is required for Unity Ads integrations.

Step 6: Test your implementation

テスト広告を有効にする

Ad Manager にテストデバイスを登録し、 Unity Ads UI でテストモードを有効にします。

テスト広告を確認する

Unity Adsからテスト広告を受信していることを確認するには、広告インスペクタで Unity Ads (Waterfall) 広告ソースを使用して単独の広告ソースのテストを有効にします。

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.getAdapterResponses() under the following classes:

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 for more details.
101 UnityAds server parameters configured in the Ad Manager UI are missing/invalid.
