Android app link not working after the application is made live in play store

Question

I have implemented Android app links based on the below links.

https://developer.android.com/studio/write/app-link-indexing.html

https://developer.android.com/training/app-links

I have hosted assetlinks file into our domain https://ourdomain/.well-known/assetlinks.json And also I have verified this using https://developers.google.com/digital-asset-links/tools/generator and from android studio's App Links Assitant also. and got verified status from both the ways.

Now when I generate a signed build and tested it via google drive links. Android app link works as expected(on click of the link the application gets open without opening disambiguation dialog for android version 6.0 and above).

After uploading the same version to the play store it's not working.

Below is the code used in the manifest file.

            <intent-filter android:autoVerify="true">
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:scheme="https"
                android:host="<ourdomain>" />
        </intent-filter>

EDIT: Android app link did work as expected for one day after uploading it to the play store. and started opening disambiguation dialog again on the second day. Any idea what could be the issue?

The same version from the play store gave me two different Statuses as Ask and Always on a different day.

adb shell dumpsys package domain-preferred-apps

When I run the above command

Answer 1

I got into the same issue as it was working perfectly on the signed apk which was not uploaded to the playstore.

Later I found out that I need to add the SHA256 key from PlayConsole By going to Application Dashboard in Play Console then Release Management --> App Signing and there you will find SHA-256 certificate fingerprint Use this SHA-256 in assetlinks.json at https://ourdomain/.well-known/assetlinks.json and then reinstall the app from playstore It started working fine for me
