Publisher first-party ID, formerly known as same app key

Note: Same app key has been renamed to Publisher first-party ID . The same app key API changed to reflect Publisher first-party ID in version 22.6.0. This change doesn't impact existing activation of same app key for Google Mobile Ads SDK versions 21.4.0 to 22.5.0. All applicable SDK versions process the identifier seamlessly.

Prerequisites: Google Mobile Ads SDK 21.4.0 or higher

The Google Mobile Ads SDK introduced Publisher first-party ID, formerly known as same app key to help you deliver more relevant and personalized ads by using data collected from your apps.

Publisher first-party ID is enabled by default, but you can disable it using the following method.

Kotlin

// Disables Publisher first-party ID, formerly known as same app key.
MobileAds.putPublisherFirstPartyIdEnabled(false)

Java

// Disables Publisher first-party ID, formerly known as same app key.
MobileAds.putPublisherFirstPartyIdEnabled(false);
