#Building

Create production-ready builds for Meta Horizon Store submission.

#Prerequisites

Ensure expo-horizon-core is installed and configured. This plugin:

• Removes prohibited permissions
• Configures Quest-specific build variants
• Sets Meta Horizon App ID
• Ensures store compliance

#Local Build

Build a production APK locally:

npx expo run:android --variant questRelease

The APK will be located at:

android/app/build/outputs/apk/quest/release/

#Expo EAS Build

Use Expo EAS for cloud builds:

#Configuration

Add a Quest-specific profile to eas.json:

{
  "builds": {
    "production-quest": {
      "android": {
        "gradleCommand": ":app:assembleQuestRelease"
      }
    }
  }
}

#Build Command

eas build --profile production-quest --platform android

#Download APK

After the build completes:

1. Download the APK from EAS
2. Sign it if needed (EAS signs automatically)
3. Upload to Meta Horizon Store

#Build Variants

expo-horizon-core provides two build variants:

• questDebug: Development build for Quest
• questRelease: Production build for store submission

#Verification

Before submitting, verify:

• ✅ App builds successfully
• ✅ expo-horizon-core is configured
• ✅ Prohibited permissions are removed
• ✅ Meta Horizon App ID is set
