Android Instant Apps on Android O up close
That little lightning bolt on the app icon means it is an Android Instant App
At last year’s Google I/O conference, we were greeted with a preview of Android Instant Apps. The idea behind them is to broaden exposure while also saving on data and storage. Where a natively downloaded Android application may be several dozen megabytes (or a few hundred megabytes) in size, not including related overhead storage or amount of data used, Android Instant Apps use only a fraction of both.
To some that may sound counter-intuitive, but the result is quite remarkable, and it expands the ways developers and businesses can reach users without necessarily forcing them to download an app or bear with a web-page, yet still use their product or service.
While Android Instant Apps is just If a friend or colleague were to send you a link (and you have a compatible device) to a Red Bull video, or an available apartment on Hot Pads, or New York Times crossword puzzle, because these early partners have been enabling Android Instant Apps (among a few dozen), it is possible you clicked on these links and used the Instant App, in lieu of an optimized web-page in Chrome.
Google has opened up the Android Instant Apps SDK to all developers now which means we are weeks away from seeing how quickly this feature is adopted. As newer devices roll out with the latest version of Android, users will have a whole new way to enjoy application experiences without sacrificing storage space or data.
