Android WEB RTC

Question

안드로이드 앱에서 화상 채팅을 위해 Web Rtc를 구현하려고하는데 오류가 표시됩니다.

E/rtc: # 
    # Fatal error in ../../webrtc/modules/audio_device/android/audio_manager.cc, line 77 
    # Check failed: HasDeviceObjects() 
    # 
    # 

build.gradle 및 NDK 지원에 대한 의존성도 추가되었습니다.

통화 initializeAndroidGlobals 먼저 코드입니다.

PeerConnectionFactory.initializeAndroidGlobals(this, true, true, true, true); 
final PeerConnectionFactory peerConnectionFactory=new PeerConnectionFactory();
