Shipping AI-generated prototypes to the Google Play Store often trips up developers who rely on vibe-coding platforms like Lovable and Emergent. A new tutorial published on DEV.to explains that while these tools accelerate initial development, neither offers a one-click publishing button. Instead, developers must navigate complex build processes to generate the cryptographically signed Android App Bundle (.aab) files required by the Play Console.

Distinct Build Pipelines for Each Platform

The guide emphasizes that Lovable and Emergent generate fundamentally different codebases, necessitating unique packaging strategies. Lovable produces standard React, Vite, and Tailwind single-page applications. To ship these on Android, developers must export the repository to GitHub, build the production dist folder locally, and wrap it using Ionic Capacitor. The process involves specific CLI commands, such as npx cap init and npx cap add android, to integrate the web app with native Android structures. Emergent, however, utilizes React Native and Expo for its mobile agent workflow. This approach allows developers to bypass local Android Studio installations entirely. The tutorial recommends using Expo Application Services (EAS Build) to compile and sign binaries in the cloud. Key steps include installing the eas-cli, logging in, and running eas build --platform android --profile production. This cloud-centric method contrasts sharply with the local build requirements of the Lovable pipeline.

Common Pitfalls and Technical Fixes

Developers face specific technical hurdles when transitioning from web previews to production binaries. For Lovable apps, the tutorial warns of blank white screens caused by Vite’s default absolute asset paths. Fixing this requires setting base: './' in the vite.config.ts file. Additionally, Firebase Google Sign-In errors occur because standard web popup calls are blocked in Android WebViews. The solution involves registering the Android SHA-1 signing certificate in Firebase and bridging native authentication methods. Emergent apps encounter different challenges, particularly when moving from Expo Go to standalone binaries. The guide highlights that EAS Build ignores local .gitignore environment files, leading to crashes if EXPO_PUBLIC_ keys are not pushed to Expo’s cloud environment. Furthermore, deep links for OAuth redirects often fail in production unless a custom URL scheme is configured in app.json and the remote EAS Keystore SHA-1 fingerprint is whitelisted.

Key Takeaways

  • Lovable apps require Ionic Capacitor wrapping and specific Vite configuration changes to resolve asset paths in Android WebViews.
  • Emergent apps leverage Expo Application Services for cloud-based builds, avoiding the need for local Android Studio installations.
  • Authentication failures in both platforms often stem from mismatched SHA-1 fingerprints and improper environment variable handling during the build process.

The Bottom Line

While AI tools democratize app creation, the gap between prototype and production remains significant. Developers must still master traditional mobile engineering practices to successfully navigate the Google Play Store's strict requirements.
