Not quite on par with a proper programming environment like desktop Linux, you can still do some useful things with Termux on a non rooted device. Only recently got into it, but it's quite cool to be able to ssh in and write scripts, use Termux API plugin and other things Worth checking out. I wish Android dev wasn't such a pia and tied to Android SDK. I just want to "make" and "./main" without 10gigs of Android crap to get a hello world app.
