You can now test certain apps on Google Play Store before installing them
Google has announced that its 'Android Instant Apps' technology is coming to the Google Play store, which allows Android users to try out apps immediately without having to install them on your mobile device.
Instant Apps were first introduced at Google’s I/O developer conference last year and, unlike native apps that have to be downloaded in full, can be run without installation. To support this, developers partition their apps into small, runnable parts, so they can start within seconds.
Load up the Play store and go to the Featured section and you'll see a selection of apps with a “Try it Now” button. Right now, the selection is pretty thin, but includes BuzzFeed, the NYTimes Crossword, Red Bull TV, Skyscanner, and a few others. However, we expect more to be added soon.
