Android: When you search for the name of an app, Google already shows you direct links to the Play Store where you can download it. Now, some users are seeing the ability to install apps without ever leaving the Google app itself. As Android Police reports, many users are seeing the ability to install apps directly from search results. As you can see in the images above, a pop-over goes through the process of confirming permissions and installing the application over the search results for the app. This is a minor change to the usual flow, which opens the Google Play Store before allowing you to install an app, but it's a convenient one.
Android Police reports that they have received enough tips from users with this feature to believe a wide rollout is in progress. When I tested this, I did not yet have this feature, and Google hasn't made an announcement. When we find out more, we'll update with information on how you can get this feature.
