Overall this is a clean, well-structured Gradle 9 + AGP 9 upgrade. The opt-outs are deliberate and well-commented. A few observations below.

gradle.properties

android.r8.optimizedResourceShrinking=true removed ✅
Correct removal — this flag becomes the default in AGP 9.0+.

android.builtInKotlin=false added ✅
Intentionally opting out of AGP's built-in Kotlin management for published library consumer compatibility. The inline comment clearly explains the intent and the migration plan ("before AGP 10"). Good practice.

android.newDsl=false added ✅
Opts out of the new Gradle DSL. The companion comment in settings.gradle.kts explains why enableFeaturePreview("TYPESAFE_PROJECT_ACCESSORS") is still needed with the old DSL. Both comments are well-placed.

settings.gradle.kts

foojay-resolver-convention plugin added ✅
Required by Gradle 9+ for JDK auto-provisioning. Version 1.0.0 is appropriate.

gradle/gradle-daemon-jvm.properties (new file)

Auto-generated by ./gradlew updateDaemonJvm. Pins the Gradle daemon to JDK 21 via foojay resolver, consistent with the project's toolchain. No issues.

Potential concern: KSP version

ksp = "2.3.6" paired with kotlin = "2.2.21" — worth verifying that this KSP version is compatible with Kotlin 2.2.21. The KSP versioning scheme has evolved, but historically the major version prefix maps to the Kotlin version. If the KSP 2.x line now uses independent versioning, this is fine — otherwise confirm compatibility.

Summary

The upgrade is well-executed with appropriate conservative opt-outs for a published library. All changes are justified and commented. No blocking issues.

🧹 Nitpick comments (1)

gradle/wrapper/gradle-wrapper.properties (1)

3-3: LGTM, but consider Gradle 9.4.1 as well. Gradle 9.2.1 meets the minimum requirement (9.1.0) for AGP 9.0.1, and using the binary distribution (-bin.zip) is appropriate for build performance. However, Gradle 9.4.1 is available as a newer stable option that also aligns with the AGP 9.0.1 upgrade.
