Google has quietly published documentation for Lightbuild, a new build configuration experience for Android projects. Lightbuild is designed as a declarative, YAML-based build configuration layer for Android.
Today, Android projects usually use either Kotlin DSL or Groovy DSL for Gradle configuration. Google says Lightbuild will become a third option once it reaches general availability.
Instead of writing build logic directly, developers describe how the project should be built. Lightbuild then converts that declarative configuration into another build system, such as Gradle, which still performs the actual build behind the scenes.
Google describes Lightbuild as a build experience aimed at streamlining tasks in Android Studio and supporting agentic developer workflows through Android CLI.
The YAML format is a big part of that. Google says Lightbuild’s build files are designed to help AI agents parse build configuration, update dependencies, and edit modules more efficiently, while keeping those changes under developer control.
Google lists three main benefits:
- Agent-friendly configuration - structured YAML should be easier for coding agents to read and safely edit.
- Android CLI integration - Lightbuild is intended to work with the same Android CLI build and test features used by developers and agents.
- Android Studio support - Lightbuild-based projects are designed to be fully supported inside Android Studio, including project templates and AI-created projects for users who have access.
