我可以使用USB直接连接两个Android设备吗？

Question

I need to write a program that will alow an Android device (running version 2.2) to send data (a simple String) to another device (also running version 2.2) via a USB connection. Are there any libraries to do that?

Answer 1

I believe those devices would have to support USB host mode in hardware. And then one of them would need to be out in storage media mode, then you'd use standard filesystem access functions. But the hardware side needs to be dealt with first. I would check out special USB host cables to see what can be done. Not all Android devices can be put into USB host mode.
