Android app links have been verified. But, still disambiguation dialog shows up

Question

When I click on the link: https://example.com/abcd on android version 6/7/8 it shows disambiguation dialog. We have already verified domain by placing json at: https://example.com/.well-known/assetlinks.json. I've done everything as per the documentation and still the link doesn't open without disambiguation. Please help me find what I'm missing.

Code in manifest:

<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="example.com"
        android:pathPattern="/abcd"
    />
</intent-filter>

Answer 1

Late to the party but I too experienced the disambiguation always popping up. For those who haven't managed to resolve this yet (or to come), go to Logcat and search for "IntentFilterIntentOp". You should be seeing something like Verification 8 complete. Success:true. Failed hosts:. This may fail (Verifying IntentFilter. verificationId:8 scheme:"https" hosts:"example.co.za" package:"za.co.example.qa".) if you've uploaded your assetlinks.json file to one domain whilst it's not accessible on other or subdomains that you've registered in your intent-filter.

It's also worth mentioning that your App would have to have been launched at least once before in order for "IntentFilterIntentOp" to perform the necessary verification. Accessing a link via App Link Testing in Android Studio should thereafter automatically open your app without the disambiguation dialog.

Answer 2

update as of 2021 with Android 12:

Android changed web intent resolution policy that effects link handling, if you follow all the new requirements your app will be given a chance if not browser will handle those, more on this here: web intent resolution requirements

/////////////////////Below behavior might still apply today//////////////////////

The Caveat here is if you install the app through playstore the default "link-handling policy" of the application with registered domains like www.example.com is set to "Handle in the app", which will open the app directly subject to intent filter verification without any disambiguation dialogues.

If you install the app by means other than playstore like through adb even though you sign it with keystore the default link handling policy is set to "Always ask" which will show disambiguation dialog even though the intent-filter verification passes for your app link.

Please try to add autoVerify="true":

<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="example.com"
        android:pathPattern="/abcd"
    />
