I'm stuck for adding global search to my app. I did everything that I should do. my question is is global search is still available for developer? I read somewhere that Google replaced it with index.
Thank you for your time and help
While global search (via the searchable.xml includeInGlobalSearch attribute) is available as part of Making Android TV Apps Searchable, the current Google Search app on phones and tablets does not support global search. As you mentioned, Google now strongly recommends using App Indexing to surface results from your app within the search results.
