Might need to search around for exact commands but the main thing is you’ll need the fdroid or source apk of termux for this to work from what I remember. So setup termux up on Obtainium or fdroid. Then inside termux pkg install syncthing should work. You might need to run the storage scripts found here https://wiki.termux.com/wiki/Internal_and_external_storage You can move over your existing syncthing exported config files (remove encryption first before exporting) to ~/.local/state/syncthing and edit the config.xml file. Remove the lines for username and password. This will allow you to create a new username and password when you run syncthing in termux. It should open a browser window to http://127.0.0.1:8384/ which is the normal syncthing web interface.
