Reference (Image Tag)

The Reference Tag is arguably the most critical configuration for a successful build. It determines the exact versions of the build tools inside the Docker container, including the Android SDK Build Tools, Platform Tools, Gradle version, Node.js version, and the framework CLI (Cordova/Capacitor).

Critical: Toolchain Matching
Builds fail most frequently because the project's required dependencies do not match the selected Image Tag. For example, if your project targets API 36, but you select the v1.x tag (which only contains SDKs up to API 35), your build will instantly fail because the required Android SDK does not exist in that environment.

Environment Specifications

Please select the tag that accurately reflects your project's age and dependency requirements.

update v2.x (Latest Environment)

Designed for modern, up-to-date applications utilizing the latest framework capabilities.

  • Framework Support: Capacitor 8+ / Latest Cordova
  • Android Gradle Plugin (AGP): Gradle 8.13
  • Android SDK: Target API 36
  • Node.js: Latest LTS
history v1.x (Stable / Legacy Environment)

A battle-tested environment for older projects that rely on legacy plugins or cannot easily upgrade their build tools.

  • Framework Support: Capacitor 7+ / Legacy Cordova
  • Android Gradle Plugin (AGP): Gradle 8.7
  • Android SDK: Target API 35
  • Node.js: Older LTS
Tip: If your project compiles successfully on your local machine but fails in the builder, check your local gradle-wrapper.properties and ensure you are selecting the Image Tag that provides the matching Gradle version.
