I'm looking for a way to sync pdfs / jpegs from an android to a e-reader (preferably kobo). If I did my preparatory work well, there's no ready made solution that are widely supported, works on most e ereader except plugging both in a computer to do the file transfert. If you have ideas, shoot. It doesn't have to be wireless, a usb cable is possible. Also I need this brainstorm ASOP (as opensource as possible) :)
