http://stackoverflow.com – An audio capture application on rooted MK809/Android 4.1.1. There is no internal mic so I am trying to use a USB one which is correctly detected as "USB Audio Device" in Settings/Sound/Sound Devices Manager/Sound Input Devices when connected. What is this device's AudioSource value to pass into AudioRecord constructor (first argument). I tried every one in MediaRecorder.AudioSource, none worked. I am only interested in reading the capture buffer, not saving into a file. (HowTos)
