Some personal notes on using Android.

Get Linux environment on Android.

note use the installer from fdroid, play store version does not work

• initial setup

  $ pkg update
  $ pkg install git vim clang make
  $ pkg install rsync

  • note will also get ssh
• shared storage

  $ termux-setup-storage

  • note make sure point to sd card (easier to share)
• create work path

  $ mkdir $HOME/work

• clone my1shell, my1codelib, my1codeapp to work path

work in progress…

Alternative: using proot-distro

• initial setup

  $ pkg update
  $ pkg install proot
  $ pkg install proot-distro

• pick/install/config a distro

  $ proot-distro install debian
  $ proot-distro login debian

• login as user (created in previous step)

  $ proot-distro login debian --user username

• shared storage

  $ termux-setup-storage

  • access SD card (@/storage/path/to/sdcard) from proot
  • refer to $HOME/storage links

DebianARM Install

• $ apt install build-essential linux-headers-arm64

• $ apt install sqlite3 libsqlite3-dev

• $ apt install apt-utils dialog git vim screen rsync

• $ apt install texlive texlive-latex-extra texlive-science xfig

also work in progress…

Dumping this here for now…
