问题

回答1:

The manifest file will remain same as specified in this link https://developer.android.com/training/app-indexing/deep-linking.html

But you can provide the extra data in the link you send to the user as www.example.com/gizmos?key=valueToSend

then in the activity you can do something like

Uri data = intent.getData();

data.getQueryParameter("key");

回答2:

Supposing that you generate a separate share link for each item. You could send some parameters along with the deep link URL and then receive them in the App. Any kind of an ID would suffice. (Source: this)

<intent-filter android:label="@string/filter_title_viewgizmos">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
    <data android:scheme="http"
          android:host="www.example.com"
          android:pathPrefix="/gizmos" />
    <!-- note that the leading "/" is required for pathPrefix-->
    <!-- Accepts URIs that begin with "example://gizmos”
    <data android:scheme="example"
          android:host="gizmos" />
    -->
</intent-filter>

Taking up this example, if the app deep links here, you can receive your intent in the corresponding activity (Here: com.example.android.GizmosActivity) and extract information from there itself.
