Google began rolling out support for the Google Play Store and Android apps on some Chromebooks in 2016. This year it looks like the company is preparing an update that will make it easier to view and interact with multiple Android apps at the same time.
Chrome Unboxed has posted some pictures of a pre-release version of Chrome OS featuring Android 7.1 integration. Up until now, the Android subsystem on Chromebooks was based on Android 6.0.
