I use the USB to serial library, you can find it here: USB Serial for Android. It doesn't require any root access. You'll need to check if your Android device supports USB host mode. Then, using a usb OTG cable and a USB to serial adapter cable you can start communicating with your serial device via RS232. There are code examples to get you started on the Github page of the USB to Serial library.
