As posted on Google is testing a splitscreen view for Android apps on Chromebooks
The latest update to Chrome OS’ Canary test channel should make multitasking on a Chromebook easier. Now, in addition to split-screening two native Chrome OS apps on your machine, you can run a Chrome OS app and an Android app side-by-side or two Android apps. It should be mentioned that Canary is pre-alpha software and isn’t exactly stable, as 9to5 Google notes, so maybe don’t try this out on your daily driver. This could be a sign that Chrome OS tablets and Chromebooks with detachable screens are en route. The video below from Chrome Unboxed, however, shows the feature running on a Samsung Chromebook Pro which suggests it’ll work on existing convertibles too.
