Set the status notification when each apk calls mic audioHAL; AudioManager.setparameter("audio_source=xxxx")；
audio record:	not configure yet	setParameters("audio_source_record=sound")
camera record:	call the 2 mics on the temple, all the sound is received, no noise reduction algorithm	setParameters("audio_source_record=camcorder")
translation:	Call 3 mics, do not receive the user's voice, but receive external voices	setParameters("audio_source_record=translation")
voice assistant:	Call the 2 mics on the temple, mainly receive the user's voice	setParameters("audio_source_record=voiceassistant")

To make sure each application has its own mic combination, please set "setParameters("audio_source_record=off" when exit.
