Integrating the app with Google search results and Chrome

Question

The official Wikipedia app somehow does that, in my app I'm using a standard intent-filter to listen for navigation to Wikipedia urls.

Is there a way to integrate with Google search? Are there any APIs available, or is this only available for the chosen ones?

Answer 1

According to the documentation, you have to add a meta tag to the pages for which you want the search to display a link to an app. For example, the Wikipedia page linked in the search result from your screenshot, has the following link in its source code:

<link rel="alternate" href="android-app://org.wikipedia/http/en.m.wikipedia.org/wiki/Apollo_17" />

I assume that you cannot add a link to your app to search results by other means: The search results also suggest users to install apps they don't have yet. Giving the power to decide which app is suggested to someone other than the owner of a page would obviously be dangerous. Another strong hint is that the documentation does not mention any alternatives.

As I remember correctly Google announced in this years Google I/O that an API to achieve this will be available from Android L

The announcement can be found in the keynote video at 33:45, although it does not say anything about how it will work
