Android Instant App Play Store Errors

Whenever I upload my base and feature APKs to Play Store I got these errors :

• You must provide a default URL for your Instant App APKs. Learn More
• Your site 'www.example.com' has not been linked through the Digital Assets Link protocol to your app. Please link your site through the Digital Assets Link protocol to your app.
• You should have at least one active APK that is mapped to site 'www.example.com' via a web 'intent-filter'.

And here is my manifest file : (EDITED)

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.ex.example.feature.productdetail">

      <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
      <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
      <uses-permission android:name="android.permission.INTERNET"/>
      <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
      <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
      <uses-permission android:name="android.permission.WAKE_LOCK"/>


      <application>

    <activity
        android:name=".activity.ProductDetail"
        android:configChanges="orientation|screenSize"
        android:screenOrientation="portrait">
      <meta-data
          android:name="default-url"
          android:value="https://www.example.com/product/12345" />

      <meta-data android:name="asset_statements" android:resource="@string/asset_statements"/>

      <intent-filter
          android:autoVerify="true"
          android:order="1"
          >
        <category android:name="android.intent.category.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>

        <data android:scheme="http" android:host="www.example.com"/>
        <data android:scheme="https" android:host="www.example.com"/>
        <data android:pathPattern="/product/12345"/>
      </intent-filter>

      <intent-filter>
         <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER"/>
      </intent-filter>

    </activity>

    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id"/>
  </application>
    </manifest>

I put the assetlinks.json file to my web site, and when I proceed test link file, it gives success. What am I doing wrong any idea? Thanks your help in advanced

This is because the default URL you specified (https://www.example.com) is not supported by the intent-filters in your Instant App (https://www.example.com/product/productId).

You will either need to update the default URL so it points to a supported URL, or add a new intent-filter that supports the default URL.
