Clarify compatibility with com.google.android.gms:play-services-ads 24.0.0

[ansf]

v24.0.0 of the Mobile Ads SDK (com.google.android.gms:play-services-ads) was released 2025‑02‑24 (see https://developers.google.com/admob/android/rel-notes#24.0.0).

The migration guide states:

Version 24.0.0 adds the onUserEarnedReward() callback in MediationRewardedAdCallback and deprecates onUserEarnedReward(RewardItem). Mediation adapters must start calling onUserEarnedReward() when the user earns a reward.

I would assume, that by the time of the release of v24.0.0, all adapters are ready for the update, but for example for the Unity adapter, there doesn't seem to be a version ready (see https://github.com/googleads/googleads-mobile-android-mediation/blob/main/ThirdPartyAdapters/unity/CHANGELOG.md).

Can you please clarify, which adapters are compatible with 24.0.0? What is the recommended way to handle updates of com.google.android.gms:play-services-ads and the adapters?

BTW, the docs for the Unity adapter state, that one should use the "Latest Google Mobile Ads SDK". If we are still required to use v23, it would be nice, if this could be updated.

Hi @ansf , thanks for the question and the update suggestions! I'm getting around to a bit of issue cleanup here.

All of our supported mediation adapters should be compatible with play services 24+, including [Unity mediation]((https://developers.google.com/admob/android/mediation/unity#android_studio_integration_recommended) - all those docs should have since been updated.

Going to go ahead and close this issue out since it's been some time, but if you see anything else that needs clarification, feel free to open a new issue!

Answering this here as well for the benefit of the community!

What is the recommended way to handle updates of com.google.android.gms:play-services-ads and the adapters?

The recommended approach is to always use the exact Google Mobile Ads SDK and adapter versions specified in our official developer documentation for each ad network partner.

We do coordinate efforts across teams to ensure that mediation adapter updates are tested and released in sync with new versions of play-services-ads. Following the documented version pairings is the most reliable way to ensure a stable integration and prevent compatibility issues.

You have correctly filed an issue here if you suspect something is out of date, or there is a version discrepancy!
