Not appy with your Chromebook? Well now it can run Android apps

Google offers beta of tricky OS-inside-OS tech

To help bridge the gap between its two mobile platforms, Google has released a beta version of a technology that allows Chrome OS users to run Android apps on their desktops.

Google OS boss Sundar Pichai first previewed the tech in March, during one of the less buzzed-about segments of his I/O conference keynote.

Dubbed the App Runtime for Chrome, it's a way of packaging Android apps so that they will launch and run on Chrome OS, via a special runtime implemented using the Chocolate Factory's Native Client (NaCl) in-browser binary execution tech.

Google says developers don't need to do any porting to get their apps running on Chrome OS. Still, it's hardly click-and-go, at least for now. Google needs to finagle each app to get it working, and so far it has chosen only four Android apps to release in Chrome OS–compatible versions.

At I/O, Pichai also said that Android developers might prefer to modify their apps to make them more compatible with the different usage scenarios found on Chrome OS.

"These applications were built for Android for the phone, so we want them to work when there is a mouse, keyboard and touch events, et cetera," Pichai said, though he added, "For developers, we want this to work with as little modifications as possible."

During his keynote, Pichai demoed cutting and pasting from a Chrome browser window into an Android app running on Chrome OS as an example of how Google is working to make running the apps feel natural and seamless.

The lucky four Android apps launched for Chrome OS on Thursday via the Chrome Web Store are Duolingo, Evernote, Kids Sight Words, and Vine.

The apps aren't compatible with the standalone Chrome browser; you'll need an actual Chromebook or Chromebox to run them.

Getting them running must have been more work than Google is letting on, however, as three of the four are apps that Pichai demoed at I/O back in March. Curiously, a fourth app shown off at I/O, Flipboard, is not part of the beta.

We also couldn't help but notice that all four apps already have browser-based versions available in the Chrome Web Store, so it's not entirely clear why you'd prefer to run the Android versions.

Nonetheless, Google says it plans to offer more Android apps for Chrome OS through the store soon, and that customers can vote for the ones they'd like to see via a web form. ®

    In brief Thieves operating for the North Korean government made off with almost $400m in digicash last year in a concerted attack to steal and launder as much currency as they could.

    A report from blockchain biz Chainalysis found that attackers were going after investment houses and currency exchanges in a bid to purloin funds and send them back to the Glorious Leader's coffers. They then use mixing software to make masses of micropayments to new wallets, before consolidating them all again into a new account and moving the funds.

    Bitcoin used to be a top target but Ether is now the most stolen currency, say the researchers, accounting for 58 per cent of the funds filched. Bitcoin accounted for just 20 per cent, a fall of more than 50 per cent since 2019 - although part of the reason might be that they are now so valuable people are taking more care with them.

  • Tesla Full Self-Driving videos prompt California's DMV to rethink policy on accidents

    Plus: AI systems can identify different chess players by their moves and more

    In brief California’s Department of Motor Vehicles said it’s “revisiting” its opinion of whether Tesla’s so-called Full Self-Driving feature needs more oversight after a series of videos demonstrate how the technology can be dangerous.

    “Recent software updates, videos showing dangerous use of that technology, open investigations by the National Highway Traffic Safety Administration, and the opinions of other experts in this space,” have made the DMV think twice about Tesla, according to a letter sent to California’s Senator Lena Gonzalez (D-Long Beach), chair of the Senate’s transportation committee, and first reported by the LA Times.

    Tesla isn’t required to report the number of crashes to California’s DMV unlike other self-driving car companies like Waymo or Cruise because it operates at lower levels of autonomy and requires human supervision. But that may change after videos like drivers having to take over to avoid accidentally swerving into pedestrians crossing the road or failing to detect a truck in the middle of the road continue circulating.

  • Alien life on Super-Earth can survive longer than us due to long-lasting protection from cosmic rays

    Laser experiments show their magnetic fields shielding their surfaces from radiation last longer

    Life on Super-Earths may have more time to develop and evolve, thanks to their long-lasting magnetic fields protecting them against harmful cosmic rays, according to new research published in Science.

    Space is a hazardous environment. Streams of charged particles traveling at very close to the speed of light, ejected from stars and distant galaxies, bombard planets. The intense radiation can strip atmospheres and cause oceans on planetary surfaces to dry up over time, leaving them arid and incapable of supporting habitable life. Cosmic rays, however, are deflected away from Earth, however, since it’s shielded by its magnetic field.

    Now, a team of researchers led by the Lawrence Livermore National Laboratory (LLNL) believe that Super-Earths - planets that are more massive than Earth but less than Neptune - may have magnetic fields too. Their defensive bubbles, in fact, are estimated to stay intact for longer than the one around Earth, meaning life on their surfaces will have more time to develop and survive.
