App link not working with navigation component

[bacnv-1260]

I was setup follow by
https://developer.android.com/codelabs/android-navigation#10
`

<argument
    android:name="myarg"
    android:defaultValue="Android!"/>

<deepLink android:autoVerify="true" app:uri="www.example.com/{myarg}" />

` and server side uploaded assetlinks.json(it's all correct) but when i clicked app link from email content it show dialog confirm open which app(it's working same as deeplink), so can you tell me my code have any happen or how can i implement app link with navigation component? Thanks
