Links Deprecation and SDK Changes

Overview:

Firebase, Google’s powerful app development platform, is undergoing critical policy and SDK changes that directly impact mobile developers—especially those building Android and hybrid apps for Indian markets.

The biggest updates to note:

  • August 25, 2025 – Firebase Dynamic Links will be deprecated
  • Firebase Admin SDK for Python has dropped support for Python 3.7 and 3.8

    Understanding these changes and acting early is key to avoiding user disruptions and backend failures.

Firebase Dynamic Links Deprecation What’s Happening?

Firebase Dynamic Links—a tool used to route users to specific app content—will be fully deprecated on August 25, 2025. This affects:

  • Email-based login links (e.g., email/passwordless login).
  • Referral links.
  • App redirection logic on install.

    • What to Use Instead?
    Google recommends:
  • App Links (Android) and Universal Links (iOS).
  • Custom URL schemes.
  • External linking tools such as Branch.io or Bitly (for analytics).

    Risks if Ignored:
  • Broken login flows.
  • Failed redirections for users post-install.
  • Lost campaign/attribution tracking.
  • Drop in user engagement and app reviews.

    • Our Solution:
    We help you:
  • Identify all dependencies on Dynamic Links.
  • Rebuild your authentication flows (OAuth/email login/phone login).
  • Set up App Links with proper Digital Asset Links & domain verification.
  • Implement fallback routing and redirection logic.
  • Preserve user data and referral attribution.
    • Firebase Admin SDK Update for Python What’s New?

    Google has upgraded the Admin SDK, dropping support for Python 3.7 and 3.8 in the latest Firebase libraries.

    If You Don’t Upgrade:

  • Admin SDK calls (auth, Firestore, FCM, etc.) may stop working.
  • Future Firebase features will be incompatible with older Python versions.
  • Security patches will not be available for unsupported versions.

    • Our Support:
  • Codebase audit to detect version dependency.
  • Migration of your Flask/Django/FastAPI apps to Python 3.9+.
  • Compatibility testing across Firebase services (Auth, Firestore, Realtime DB).
  • Deployment support for upgraded environments (GCP, Firebase Hosting, etc.).

    • Why This Matters More for Indian Developers

    India’s developer community relies heavily on Firebase for fast, cost-efficient app development. With Firebase being central to :

  • Startups.
  • EdTech and FinTech platforms.
  • On-demand and logistics apps.
  • Cross-platform (Flutter/Ionic) applications.

    • These changes demand immediate action to avoid downtime and lost users in high-volume environments.

    Final Thoughts

    These updates reflect Google’s broader shift toward performance, security, and future scalability. But they also come with risks—especially for developers who delay upgrades or lack internal resources.
