Are there any USB features for Android devices (all user devices, not implemented)?I'm curious because I might want to make an application that transfers everything via USB
There are no short answers and people are tied for it , but depending on what you intend to do, implementing bluetooth Android is much easier. (and you can consider Bluetooth as a basic serial connection if it is oblique)
