As far as I can tell, this feature has not been confirmed by Google, and everyone cites Chrome Unboxed rather than testing on their own Chromebooks. That said, Chrome Unboxed has a video of the feature in action, and I don’t have a Chromebook of my own, so I’ll just label this as a rumor even though I’m confident that it is true.
The feature? Android apps will soon be able to run in the background on Chrome OS. It is apparently possible using the beta channel Chrome OS 64, but that doesn’t mean it will land in Chrome OS 64 stable. This pushes Android (the app platform) significantly closer to a desktop-style platform, albeit when hitching a ride on Chrome OS.
I’m curious how much control will be given to Android developers, though. It seems like Google would want apps to do things like reduce their workloads when unfocused. If so, would they bring this feature to Android proper? Or would it be a Chrome OS-specific feature that developers need to specifically target?
Either way, it looks like Google is working on it.
