06-16 12: 05: 46.802: E / chromium (15693): [ERROR: audio_manager_android.cc (239)] Unable to select an audio device

I am creating an application to connect video / audio in android using xwalkview. I get this error 90% of the times not every time I make an audio / video call, and because of this, I do not receive video from both sides. I added permissions Record_Audio, camera, Modify_audio_settings.
