You need the USB OTG (On The Go) cable that is appropriate for your Android, a USB to RS232 converter, a null modem, and db9 to db25 adapter.
Some Androids don't support OTG, and those just won't work. Others support OTG but limit the amount of power they're willing to output, and those will need a powered USB hub between the Android and the RS232 adapter. I'm still investigating Bluetooth options. Amazon's Bluetooth to rs232 options are pretty pricey for finished, packaged devices. Raw circuit boards are cheaper but then I'd have to make my own box.
