I would need to code an application that allows two Android devices to communicate using a microUSB/microUSB OTG cable.
Is this possible? How?
I couldn't find any practical example of this, and I'm not even sure it's possible: by default, when two devices are coected, the host one can see files on the guest one, so I guess communication is handled by the operating system, not an user app.
Does it need root?
Any help is appreciated! Thanks
