ANDROID DEEP LINK DIAGNOSTICS

Android App Links Checker

Diagnose the public Digital Asset Links configuration Android uses to associate a website with an installed application.

What this checker can prove

This tool verifies the public assetlinks.json side of Android App Links. It checks the website association document but does not inspect your APK/AAB, manifest intent filters, installed package state, or device verification cache.

Use it when

An App Link starts opening in the browser instead of the app.
You changed signing keys, package identifiers, or deployment environments.
You need to confirm that the website advertises the expected SHA-256 certificate fingerprint.
You want to detect association drift after a web deployment.
