Engineers at Google started work on a new Terminal app for Android a couple of weeks ago. This Terminal app is part of the Android Virtualization Framework (AVF) and contains a WebView that connects to a Linux virtual machine via a local IP address, allowing you to run Linux commands from the Android host. Initially, you had to manually enable this Terminal app using a shell command and then configure the Linux VM yourself. However, in recent days, Google began work on integrating the Terminal app into Android as well as turning it into an all-in-one app for running a Linux distro in a VM.

There already are a variety of ways to do this today, but having it as a supported feature implemented by Google is very welcome. This is also going to greatly increase the number of spammy articles and lazy YouTube videos telling you how to "run Ubuntu on your phone", which I'm not particularly looking forward to.
