Android Deep Linking with wild card type in paths not working

[Manikanta Garikipati]

I'm trying to perform deeplinking for my android where in i want a particular activity to open for all the paths of following type:

http://example.com/asdf/asdf/product/someinfo
http://example.com/asdf/product/some

http://example.com/asdf/asdf/asdf/asdf/asdf/product/someinfo 

http://example.com/product/some

basically i need a particular activity to open if it has /product/ in the url path( domain).

this is my manifest setup:

 <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:host="@string/deeplink_host"
          android:pathPattern="/.*/product/.*"
          android:scheme="http"/>
 </intent-filter>

But the above link is working only if the url is

http://example.com/product/some

Not for the other type of url's where the url can have multiple info (separated with / ) before /product/

I've tried changing the configurations but in vain..

Can anyone help me through this?
