Additional Chromebooks are getting access to the Play Store, meaning they can now install and use a plethora of Android apps. This is done through the beta channel much like the other Chromebooks which have already received access, as Google has not yet updated Chrome OS to feature the Play Store in the stable channel. That being said, expansion of the Play Store access through the beta channel to more Chromebooks could mean that a stable release of the update is nearby. In total there are now four more Chromebooks which can open up the Play Store app, which joins the likes of devices such as the Acer Chromebook R 13, the Samsung Chromebook 3, the Dell Chromebook 13 and more.
As for the newly added Chromebooks, according to Chrome Unboxed who discovered the details, the models include the HP Chromebook 13 G1, two more Chromebooks from Acer with the Chromebook 14 and the Chromebook 15, and one from Toshiba with the Chromebook 2. If you have any one of these Chromebooks you can switch over to the beta channel now and start using the Play Store, but you'll also need to do a few more things before the Play Store actually pops up. Luckily the steps that need to be taken are rather simple and they don't take too long to complete.
After switching over to the beta channel which can be done by navigating to settings, then clicking about Chrome OS, and then finally clicking on change channel and choosing beta, you'll need to move to developer mode. After you're in developer mode, you'll want to hit the CTRL, ALT, and T keys simultaneously which is the keyboard shortcut for the Crosh tab. Once that's done, type shell into the prompt and hit the enter key. From here you'll need to type a few lines into the command prompt, but you can also simply copy and past as the following text is what you would need to type up. That said, you'll also want to make sure that each bit of text is on its own line, so you'll need to hit enter after each line is added in. In the command, type up or copy and paste sudo su, sudo cp /etc/chrome_dev.conf / usr/local/, sudo mount --bind /usr/local/chrome_dev.conf /etc/chrome_dev.conf, and finally the last line which is sudo echo "--enable-arc ">> /etc/chrome_dev.conf. Also make sure not to enter in any of the commas or the period that are listed here, just the words separated by the commas, and hit enter to make a new line. Once this is done you can enable the Play Store by simply logging out of the Chromebook and logging back in as you don't have to reboot the Chromebook like you did with some of the other models.
