So, I tried to implement indexing applications to enable the "Open in application" function from a Google search (in a Chrome application).
I have completed the following sections from google docs https://developers.google.com/app-indexing/ :
Add deep binding to your application
<activity
android:name=".DeepLinkActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="http"
android:host="dl.mysite.com"
android:pathPattern="/" />
</intent-filter>
</activity>
Plug in app
I checked and approved the website from the webmaster console and Play.
Provide deep links
<link rel="alternate" href="android-app://com.MyApp.MyApp/http/dl.mysite.com/" />
"android-app://com.MyApp.MyApp/http/dl.mysite.com/" https://developers.google.com/app-indexing/webmasters/test, .
