Build me a simple file sharing app that uses FTP so I can move files between devices easily.

I want a clean Kivy based app with a basic screen to connect to an FTP server, browse files and folders, upload files from the device, download files, and delete or rename items if possible. Make it easy to enter the server address, username, and password, then show connection status and any errors in a friendly way. Keep the interface simple and mobile friendly, since I may want to run it on Android too.

Please wire up the main app flow, the screens, and the file actions so it feels usable right away. If you need to check current docs or best practices for any Kivy or FTP details, go ahead and look them up online.
