Java Android WebRTC提供创建抛出错误和Ice Gathering或trickling没有发生

Question

我正在使用 Gradle 依赖项 implementation 'org.webrtc:google-webrtc:1.0.30039'
这是错误:

E/rtc: Fatal error in: gen/sdk/android/generated_metrics_jni/../../../../../../../../usr/local/google/home/sakal/code/webrtc-aar-release/src/sdk/android/src/jni/jni_generator_helper.h, line 94 last system error: 0 Check failed: !env->ExceptionCheck() A/libc: Fatal signal 6 (SIGABRT), code -6 in tid 11556 (network_thread ), pid 11515 (est.applicatoin)

onSignalingChange: HAVE_LOCAL_OFFER 是异常前的最后一次日志调用。

创建了一个 SDP，但没有发生 ICE 滴流，即 OnIceGathering 或 OnIce候选人根本没有被调用。

Java Activity 代码:

public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
DataChannel mainDataChannel;
PeerConnection mainPeerConnection;
PeerConnectionFactory factory;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    initializePeerConnectionFactory();
    initializeMyPeerConnection(); // Connection Initialization.
    startConnection(); //Getting the offer


private void initializePeerConnectionFactory() {

    PeerConnectionFactory.InitializationOptions initializationOptions =
            PeerConnectionFactory.InitializationOptions.builder(this)
                    .setEnableInternalTracer(true)
                    .createInitializationOptions();
    PeerConnectionFactory.initialize(initializationOptions);

    PeerConnectionFactory.Options options = new PeerConnectionFactory.Options();
    factory = PeerConnectionFactory.builder()
            .setOptions(options)
            .createPeerConnectionFactory();
}

private void startConnection() {
    Log.d(TAG, "startConnection: Starting Connection...");
    //CreateOffer fires the request to get ICE candidates and finish the SDP. We can listen to all these events on the corresponding observers.
    mainPeerConnection.createOffer(new SimpleSdpObserver() {
        @Override
        public void onCreateSuccess(SessionDescription sessionDescription) {
            Log.d(TAG, "onCreateSuccess: " + sessionDescription.description);
            mainPeerConnection.setLocalDescription(new SimpleSdpObserver(), sessionDescription);
        }

        @Override
        public void onCreateFailure(String s) {
            Log.e(TAG, "onCreateFailure: FAILED:" + s);
        }
    }, new MediaConstraints());
    Log.d(TAG, "startConnection: Start Connection end");
}

private void initializeMyPeerConnection() {
    Log.d(TAG, "initializeMyPeerConnection: Starting Initialization...");
    mainPeerConnection = createPeerConnection(factory);

    mainDataChannel = mainPeerConnection.createDataChannel("sendDataChannel", new DataChannel.Init());//Setting the data channel.
    mainDataChannel.registerObserver(new DataChannel.Observer() {
        @Override
        public void onBufferedAmountChange(long l) {

        }

        @Override
        public void onStateChange() {
            //Data channel state change
            Log.d(TAG, "onStateChange: " + mainDataChannel.state().toString());
        }

        @Override
        public void onMessage(DataChannel.Buffer buffer) {
            Toast.makeText(MainActivity.this, "Got the message!", Toast.LENGTH_SHORT).show();
        }
    });
    Log.d(TAG, "initializeMyPeerConnection: Finished Initializing.");
}

private PeerConnection createPeerConnection(PeerConnectionFactory factory) {
    List<PeerConnection.IceServer> iceServers = new LinkedList<>();
    iceServers.add(PeerConnection.IceServer.builder("stun:stun.l.google.com:19302").createIceServer());
    PeerConnection.RTCConfiguration rtcConfiguration = new PeerConnection.RTCConfiguration(iceServers);
    PeerConnection.Observer pcObserver = new MyPeerConnectionObserver(TAG, mainPeerConnection);

    return factory.createPeerConnection(rtcConfiguration, pcObserver);
}

}

我遇到了同样的错误并通过添加这一行来解决它

android.enableDexingArtifactTransform.desugaring=false

在 gradle.properties文件
