If you're serious about wanting to deal with plaintext on Android, I recommend installing Termux and learning how to use the Nano text editor (via Termux). Here are some links to help you get started there. Also, I recommend getting a bluetooth keyboard.
- https://f-droid.org/en/packages/com.termux/ (download Termux; it's also on Google Play, but the latest version is here; scroll and click the link that says 'Download apk'--not the big button that says 'DOWNLOAD F-DROID', unless you want to install F-Droid and download it through there, which is said to be more secure; if you've never installed an .apk file before, you'll probably need to change an Android setting that lets you do it)

- https://www.growspice.com/A-desktop-user-s-guide-to-Nano-a-command-line-text-editor-td3471.html (How to use the nano text editor.)
Okay, so once you have Termux installed, you basically have a Linux command-line app; no GUI, but you don't really need one terribly. You can install and use all sorts of programs that make your tablet useful--and you can make your own, if you're a programmer. As an added bonus, both Termux and Nano make it easy to multi-task once you learn how (in Termux ctrl+alt+c makes a new terminal; ctrl+alt+up/down moves between them; in Nano, you can move between open text files with alt+left/right).
So, in Linux, to create a text file, you can do it plenty of ways:
touch myFile.txt
(that will create it if it's not there)- Type
nano myFile.txt
edit it, and save it.
Stuff like that. Learning how to use the Linux command-line will be important if you take this approach. You'll want to know commands like this:
ls
to show the contents of the current working directorycd myDirectory
to change the directory to myDirectory- Follow just about any command with
--help
(e.g.nano --help
) to learn more about how to use it.man whatEverMyCommandIs
also helps (it opens the manpage for it, if available). rm myfile
to delete a filerm -r myDirectory
to delete a directory/foldermkdir myDirectory
to make a new directorychmod +x myFile
to make a file executable./myExecutableFile
to run an executable file that is in the current directory.exit
to exit the shell (note you can typebash
to create a new one running inside of the current one, so if you exit, you'll return to the old one)pkg install myApp
to install a program called myApp (if it exists in the package manager); I don't remember if Nano comes pre-installed; if it doesn't, typepkg install nano
.- ctrl+c and ctrl+z are useful if you need to force quit a running program.
- Press tab to autocomplete stuff you're typing (like file and directory names).
- If you can't find a program for your purpose, see if someone has made one with Python; Python works on Termux, and so does pip (so, you've got access to lots of stuff).
There are more Termux-related apps on F-Droid, if you want to be able to do even more stuff with that.
