SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents failed Google Play submissions by helping you verify that your Expo/EAS Android build artifact is correctly configured, signed, and policy-compliant before you upload.

Core Features & Use Cases

  • App Bundle readiness checks: Validates that you are producing an Android App Bundle (.aab) for Play production/testing tracks and not accidentally shipping an APK.
  • Release configuration verification: Confirms package ID stability, versionCode/versioning rules, runtimeVersion/OTA compatibility, and target SDK gate expectations.
  • Credentials and submission prerequisites: Helps ensure signing keys, service account setup, and Play Console prerequisites are aligned with what EAS Submit requires.

Quick Start

Ask the skill to check your Expo project for Google Play release readiness using your eas.json, app configuration, package.json, and the generated Android build output from an EAS production build.

How do I check if my Expo EAS Android build is ready for Google Play submission?▼

To check Google Play release readiness, validate your EAS Android build artifact for correct App Bundle format, signing credentials, package ID stability, and unique increasing versionCode handling before upload.

Why does Google Play reject my Expo EAS Android app bundle upload?▼

Google Play may reject your EAS Android app bundle upload if the build format is incorrect, signing keys are mismatched, or the versionCode is not uniquely increasing. Validating android.package stability and Play upload signing expectations prevents submission failures.

What is runtimeVersion policy for OTA updates in Expo EAS builds?▼

Do I need an Android App Bundle or APK for Expo EAS Google Play production tracks?▼

You need an Android App Bundle (.aab) for Expo EAS Google Play production and testing tracks. Release readiness checks validate that your EAS build is configured to produce an .aab and not accidentally shipping an APK.

What signing credentials are required for EAS Submit to Google Play?▼

EAS Submit to Google Play requires proper signing keys, service account setup, and Play Console prerequisites. Release readiness verification helps ensure these credentials are aligned with what the EAS Submit workflow expects.

How do I validate versionCode rules for Expo EAS Android releases?▼

To validate versionCode rules for Expo EAS Android releases, check that each build uses a unique, increasing versionCode and that your android.package remains stable across versions to satisfy Google Play submission prerequisites.
