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.
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 directory
cd myDirectory
to change the directory to myDirectory
- Follow just about any command by
--help
to learn more about how to use it man whatEverMyCommandIs
also helps.
rm myfile
to delete a file
rm -r myDirectory
to delete a directory/folder
mkdir myDirectory
to make a new directory
chmod +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 type bash
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, type pkg install nano
.
- 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.
