About a month ago, we reported that Google enabled developers to feed content within apps to them via a protocol named App Indexing.

Well the fruits of that labor is not a reality, at least for some developers. Some Android apps that have participated in the App Indexing now may show up for searches done on Android phones.

What I mean is that if you search for something on the Google search app or on the Android browsers and if you have an app that matches the query and it has content that matches, it may show the app in the search results with an open button. When you click that button, it will open the app and take you directly to the content in the app.

Here is an animated GIF of it in action from Google:
