Using the android(6.0) phone's USB port, I performing a project about audio in/output.
During the call operation, it does not work that.(but Music play is normal) There are following questions: 1) During a call, Mic/Speaker output is possible via USB port? 2) During a call, can receive button event(ex: HID) via USB? (A simple volume control / Make Call, etc ...) 3) For supported these function, need to make an application or rooting android phone(OS)? 4) Need to specific USB protocol for MIC/Speaker in/out? Thanks, Juno. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
