Google runs two operating systems, Android for mobile devices and Chrome OS for laptops and at the moment there is no unified advanced ecosystem.
It seems, however, that the Mountain View giant is working to increase integration and points of contact between these two operating systems.
According to what we learn from a commit called “OneChrome demo”, developers are working on a feature that lets you share phone numbers between systems (users should be able to send the number found online on the Chromebook to their own Android device, the phone should open a dialer with the number already typed in, so you will be able to initiate a call with just one tap.
The OneChrome commit also includes clues about sharing the clipboard between Chrome OS and Android and both of these connections are protected with end-to-end encryption (so you can share phone numbers and notes without having to worry about them falling into the wrong hands).
There also appears to be a third feature in the works, namely the synchronization of the Wi-Fi password between Android and Chrome OS devices.
And about the integration between these two operating systems, Google team is working on some important changes related to support for Android apps on Chrome OS.
In particular, through the use of the system called ARCVM (ARC Virtual Machine), the goal of the developers is to guarantee greater security and the possibility of easily recovering in case of problems.
Furthermore, by isolating the Android apps from Chrome OS, the application sideload would be allowed without entering the developer mode, a feature much requested by users. It would also be possible to install Android Studio on a Chromebook, develop an app and test it on the device without being in developer mode.
At the moment, however, this project is still under development and there are no guarantees that it will not be put aside.
