How should I properly implement google app indexing for android. I mean should I care about local autocompletion and web search separately? Here are two URLs:
https://codelabs.developers.google.com/codelabs/app-indexing/#0
https://developers.google.com/app-indexing/android/publish#add-app-indexing-api-calls
Which one should I use? What is essetial differnce between these two guides? Is the first one for autocompletion only, and the second one for just ranking web pages?
Those two documents are the same. Codelab will get you started on how to use app indexing API and how does it work. And https://developers.google.com/app-indexing/android/publish is the guide for adding app indexing api to your app.
