Android Instant Apps is a game-changer for the mobile Web. Announced at Google I/O today, Instant Apps lets developers take advantage of modules that allow mobile Web users to use an application without actually installing it.
When clicking a link, Google Play runs the app instantly by only fetching the pieces of the app you need at that moment. The first example showed the user clicking a Buzzfeed Video link to view a recipe and being transported to the appropriate part of the application — all in a span of about two seconds.
