Use microphone in webrtc & media recorder simultaneously in Android?

问题

I am using webrtc for video calling in android. I am simultaneously screen recording after call is connected in sender end. I am getting this error log in sender end. Receiver end voice is not hearing when screen recording is started using MediaRecorder. I think webrtc is not streaming audio to receiver end when media recorder is started using microphone.

Error

AudioRecord: start() status -38
