AppLinks on Android 12 - opens browser only

Question

I have the following manifest code:

<activity
        android:name=".InterceptorActivity"
        android:launchMode="singleTask"
        android:parentActivityName=".HomeActivity"
        tools:ignore="UnusedAttribute"
        android:theme="@style/Theme.Startup"
        android:exported="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"/>
            <data android:scheme="http"/>
            <data android:host="www.mysite.com"/>

            <data android:pathPrefix="/myPage"/>
            <data android:pathPrefix="/myFavourites"/>
       </intent-filter>
    </activity>

assetlinks.json looks ok and uploaded correctly. But all applinks still opening only in browser, and I see, that app support the link, but it's unchecked.

Also command "adb shell pm get-app-links "com.myapp.android" returns

com.myapp.android:
ID: 893......
Signatures: [13:03....DA]
Domain verification state:
  www.myapp.com: legacy_failure

Why? Please help.

Answer 1

The reason was in incorrect file syntax. The correct is:

[
  {
    "relation": [
      "delegate_permission/common.get_login_creds"
    ],
    "target": {
      "namespace": "web",
      "site": "{siteurl}"
    }
  },
  {
    "relation": [
      "delegate_permission/common.get_login_creds"
    ],
    "target": {
      "namespace": "android_app",
      "package_name": "com.my.app.android",
      "sha256_cert_fingerprints": [
        "B4:...:9M"
      ]
    }
  },
  {
    "relation": [
      "delegate_permission/common.handle_all_urls"
    ],
    "target": {
      "namespace": "android_app",
      "package_name": "com.my.app.android",
      "sha256_cert_fingerprints": [
        "B4...9M"
      ]
    }
  },
  {
    "relation": [
      "delegate_permission/common.handle_all_urls"
    ],
    "target": {
      "namespace": "android_app",
      "package_name": "com.my.app.android.dev",
      "sha256_cert_fingerprints": [
        "BK...9Q"
      ]
    }
  }
]
