Operating System Integration

This page explains how iOS and Android treat deep links (universal/app links, URL schemes) and how ULink bridges the two systems. Implementation steps now live under Getting Started.

iOS deep linking model​

  • Universal Links: HTTPS URLs tied to your bundle ID via the Apple App Site Association (AASA) file. Tapping the link launches the app if the domain is associated; otherwise Safari opens.
  • Custom URL schemes: myapp:// routes that act as fallbacks when the domain is unverified or during testing.

ULink workflow

  1. You connect a shared.ly or custom domain inside the dashboard.
  2. ULink serves the AASA file for that domain and resolves incoming HTTPS traffic.
  3. The iOS SDK listens for both universal links and URL scheme opens, turning them into ULinkResolvedData events with parameters, metadata, and analytics context.

Android deep linking model​

  • Android App Links: Intent filters plus a Digital Asset Links JSON file that proves your domain is owned by the app.
  • Custom schemes: myapp:// or other URIs handled by <intent-filter> entries.

ULink workflow

  1. Point your <intent-filter> host to the shared/custom domain configured in ULink.
  2. ULink hosts the Digital Asset Links JSON so Android trusts the app-domain association.
  3. The Android SDK captures implicit intents, prevents duplicate handling, and emits resolved deep link data via Kotlin flows (and through the Flutter bridge when used).
  • Unified links: per-platform URLs with store/web fallbacks. No app integration is required.
  • Dynamic links: include structured payloads for in-app navigation. The SDK ensures installation/session context is present so analytics stay accurate.
