If your device detects headphone in 'getevent -l' like:
On headphone insert:
/dev/input/event8: EV_SW SW_HEADPHONE_INSERT 00000001
/dev/input/event8: EV_SW SW_MICROPHONE_INSERT 00000001
/dev/input/event8: EV_SW SW_JACK_PHYSICAL_INS 00000001
On headphone removal:
/dev/input/event8: EV_SW SW_HEADPHONE_INSERT 00000000
/dev/input/event8: EV_SW SW_MICROPHONE_INSERT 00000000
/dev/input/event8: EV_SW SW_JACK_PHYSICAL_INS 00000000
but not in the android system, you should enable this to use /dev/input/event
to detect the headphone/microphone jack.
