Android App Link
An https address Android opens directly in a verified app, authorised by an assetlinks file and the app's signing fingerprint.
Updated August 14, 2026
An Android App Link is an https address that Android opens straight in your app, with no chooser dialog and no browser stop. It is the Android counterpart of a Universal Link, and it works the same way: the domain vouches for the app.
Verification runs against /.well-known/assetlinks.json on the host in the link. That file lists the package name and the SHA-256 fingerprints of the certificates the app is signed with, and Android checks it when the app is installed. The same response rules apply as on the other platform — status 200, no redirect, application/json, no transport compression.
The fingerprint is where most setups go wrong. When Play signs your app, the certificate users receive is not the one on your build machine, so the fingerprint from Play Console has to be listed too; publishing only the upload fingerprint produces links that verify in local testing and quietly fall back to the browser for real users. List every fingerprint that is genuinely in circulation and run the file check against your live domain.
