Deep linking guides, migration tutorials, attribution walkthroughs, and engineering insights for mobile developers and small teams.
Implementation and debugging for iOS and Android, from the AASA file to deferred installs.
What is deep linking? Learn how universal links, app links, and deferred deep links work. Covers iOS, Android, and cross-platform implementation.
Universal Links opening Safari instead of your app, or opening the app but doing nothing? Triage both failures fast: testing mistakes, AASA and entitlement issues, and the cold-start handler bug.
Universal Links opening Safari instead of your app? Work through this apple-app-site-association debug checklist: AASA fetch, Apple's CDN cache, appIDs, components, and the device-side gotchas.
App Links opening a chooser dialog instead of your app? Work through this assetlinks.json autoVerify debug checklist: the Play App Signing SHA-256 trap, package_name, the intent-filter, multi-host cascade, and the adb verification commands.
A vendor-neutral Swift walkthrough of deferred deep linking on iOS: why iOS has no native support, the match cascade (IDFV, fingerprint, raw signals), the ATT and Private Relay reality, and a one-call first-launch implementation.
