Purpose

Upgrade Android build tooling in small verified steps while preserving module structure, CI and dependency compatibility.

When to use

Migrating to AGP 9 or newer Kotlin tooling.
Fixing Gradle sync errors after an upgrade.
Modernizing Gradle Kotlin DSL, wrapper or version catalogs.

Inputs to inspect

settings.gradle.kts
Root and module build.gradle.kts files
gradle/libs.versions.toml
gradle/wrapper/gradle-wrapper.properties
CI workflow files
Compose and Firebase BoM usage

Required workflow

Record current Gradle, AGP, Kotlin, Compose and Firebase versions.
Check compatibility before editing.
Upgrade one tooling family at a time.
Run sync/build validation after each step.
Document rollback commands and residual risks.

Rules

Do not upgrade every dependency blindly.
Do not mix alpha/beta versions unless requested.
Do not change module structure without a reason.
Keep version catalog aliases stable when possible.
Preserve build variants and signing boundaries.
