AdMob 24.1’s Kotlin floor can block an otherwise ready launch

An SDK upgrade can become a launch dependency through the build toolchain, even when the game’s ad placements are unchanged. The AdMob 24.1 Kotlin requirement is a concrete example worth preserving in an inherited project’s compatibility record.

Check the environment that produces the artifact

Our recommendation is to capture the resolved Kotlin version and the dependency version from the release build. A developer’s working local environment is helpful, but it is not the same evidence as a successful build in the service that produces the submitted artifact.

If a publisher receives binaries from an external studio, ask for the build record rather than a broad assurance that dependencies are current. The purpose is to make a failure reproducible and assignable. It is not to require every growth operator to understand the implementation details.

Protect the release dependency in the media plan

Where new creative depends on a game update, track the build as a prerequisite with an owner and a fallback date. Where the live game already supports the campaign promise, determine whether the SDK upgrade is actually on its critical path.

The provided card records a historical compatibility change. It does not claim a current studio build is broken or recommend a toolchain version independently of the full project. The next check is a concrete release artifact and its build evidence, followed by the usual integration and player-experience verification.

The governing record is Android release notes — 24.1.0. This edition checks the provider documentation; it does not inspect a studio account or certify a shipped build.
