Actions on Google is coming to Android and iOS, support for transactions included
Google announced it would expand the availability of its voice-activated apps to the new platforms of Android and iOS. Previously, the Mountain View company promised to bring Actions on Google functionality on Pixel smartphones and within the Allo chat app.
Once Actions on Google is fully integrated within Android and iOS, users will be able to ask the Google Assistant to play their favorite song via Spotify or Apple Music. Ordering and paying for food will be possible as well, as long as developers add support for Actions on Google for their apps.
