Ask HN: How to use Android phones as programming environment?

I have to live without a laptop for about a month. I am looking for the best practices for programming from an Android phone, (and with a big screen Android TV if required). My phone has 8GB of RAM and is rooted. I am a regular user of Vim/ Emacs and would like to use those rather than GUI apps.

What's your experience with bluetooth keyboards? Has anybody used Android TVs as the display with proper GNU/Linux installations on the phone?
