Indexing doesn't work for Public content and Personal content

[IgorGanapolsky]

Steps to reproduce:

1. Open the app-indexing project in Android Studio
2. Launch the app indexing app on a device
3. Run the following command from terminal:

adb -s 01a4968dd882b783 shell am start -a android.intent.action.VIEW -d "http://recipe-app.com/recipe/pierogi-poutine" com.recipe_app

4. Add a note on the recipe activity that opens

Expected result
public and personal content should be indexed and searchable like described here: https://codelabs.developers.google.com/codelabs/app-indexing/#12

Actual result
content isn't indexable nor showing up google search results on the device
