You’ve been able to run Android apps on some Chromebooks since mid-2016 by enabling access to the Google Play Store and then downloading and installing apps from the store. You can also sideload Android APK files, but you need to enable developer mode to do that… which will wipe your data and loosen some of the security features of a Chromebook.
Soon it may be possible to sideload Android apps that may not be available from the Play Store (or when using a Chromebook in China or other places where Google Play is not available).
But it looks like the feature will only be available for enterprise users, at least initially.
As spotted by Chrome Story, there’s a recent Chromium commit labeled “add ARC sideloading device policy,” that adds a new policy to “give enterprise administrator control over allowing APK sideloading for Chrome OS / ARC users.”
ARC, by the way, stands for Android Runtime for Chrome.
Anyway, as the code commit makes clear, the idea is to let you sideload apps… but it’s aimed at IT administrators who would presumably enable access on some or all of the Chrome OS devices under their control. It’s not quite as simple as a switch that casual users would be able to flip.
Reading through the bug report associated with this commit provides some clues for why that might be the case. Essentially when you run a web app on a Chromebook, it’s sandboxed to keep processes running in a browser window or tab from affecting the underlying operating system. This is part of the reason Chrome OS tends to be speedy even on relatively low power hardware and one of the reasons the operating system doesn’t need any additional anti-virus software to keep you safe from malware.
Android apps do have more access to the operating system kernel, but Google runs security scans on software uploaded to the Play Store. The system isn’t perfect and sometimes malware or spyware can slip through the cracks. But generally speaking if you install an app from the Play Store on a Chromebook, it’s been scanned for known malware and it should be at least as safe to use on a Chromebook as an Android app running on your phone.
Of course, most Android phones do let you install apps from “unknown sources” just by checking a box. But while developers have been working behind the scenes on bringing support for apps from unknown source to Chrome OS and ARC, it sounds like the developers have been hoping to balance security and usability.
As it stands, the idea is to make it possible… but not necessarily easy. Users should know that there’s a potential security trade-off to enabling support for apps from unknown sources. It looks like the feature may initially be available to IT administrators, who will hopefully know what they’re getting into if they decide to sideload apps. But it’s possible that Google could eventually roll out the feature to other users… possibly with a warning that’s even bigger and scarier than the one already included when you enable apps from unknown sources in developer mode:
“when you run a web app on a Chromebook, it’s sandboxed […]. This is part of the reason Chrome OS tends to be speedy even on relatively low power hardware”. I don’t understand: how does sandboxing make an OS faster?
May be because if you clear cache you clear much everything you’d like? Because when you uninstall smth from Windows, it’s stills floating there and here…
Sandboxing is the temporary isolation of a running program from the crucial operating subsystem for security purposes. Containering is the permanent isolation of a program.
While that’s good news, I’d rather that Google enhance ARC to support removable storage. Currently, it can’t access SD cards (for those chromebooks with support for SD Cards) nor most of the internal file system on the ChromeOS side. The only file system space that is commonly accessible by both ARC and ChromeOS is the “Downloads” folder. (this is something that is never mentioned in any discussion of chromebooks)
Great. Now they should allow full Linux desktops like Samsung is planning with Linux On Galaxy (without DevMode)
Some kind of native Crouton would be very useful.
