Describe the bug
Encountering a FATAL Error with the message "java.lang.UnsatisfiedLinkError: dlopen failed: library "liblkjingle_peerconnection_so.so" not found" when attempting to establish a Peer Connection.

Here I'm attaching the full error message with stack trace:

I/Process (13274): Sending signal. PID: 13274 SIG: 9
Lost connection to device.

Exited.

To Reproduce
Invoke the creation of a Peer Connection by calling the RTCPeerConnection as follows:
RTCPeerConnection pc = await createPeerConnection(configuration, offerSdpConstraints);

Expected behavior
The process should seamlessly execute all necessary steps, resulting in the successful establishment of a VideoCall connection.

yes, fixed in https://github.com/flutter-webrtc/flutter-webrtc/releases/tag/0.9.48%2Bhotfix.1,

You just need to delete pubspec.lock in your project and run flutter pub get again.

The method for accessing user media is invoked as follows:

MediaStream stream =
await navigator.mediaDevices.getUserMedia(mediaConstraints);
setState(() {
_localVideoRenderer.srcObject = stream;

}

This method is utilized in the following context:

_createPeerConnection(
{required DocumentReference<Object?> roomRef,
required bool isJoining}) async {
_localStream = await _getUserMedia();

RTCPeerConnection pc =
    await createPeerConnection(configuration, offerSdpConstraints);

pc.addStream(_localStream); // I presume that the error is triggered by this line of code.

The method for accessing user media is invoked as follows:

_getUserMedia() async { MediaStream stream = await navigator.mediaDevices.getUserMedia(mediaConstraints); setState(() { _localVideoRenderer.srcObject = stream; }); return stream; }

This method is utilized in the following context:

_createPeerConnection( {required DocumentReference<Object?> roomRef, required bool isJoining}) async { _localStream = await _getUserMedia();

RTCPeerConnection pc =
    await createPeerConnection(configuration, offerSdpConstraints);

pc.addStream(_localStream); // I presume that the error is triggered by this line of code.

pc.onIceCandidate = (iceCandidate) {
  var callerCandidatesCollection = roomRef.collection("callerCandidates");
  var calleeCandidateCollection = roomRef.collection("calleeCandidates");

  if (iceCandidate.candidate != null) {
    debugPrint(jsonEncode({
      'candidate': iceCandidate.candidate,
      'sdpMlineIndex': iceCandidate.sdpMLineIndex,
      'sdpMid': iceCandidate.sdpMid,
    }));
    if (isJoining) {
      calleeCandidateCollection.add(iceCandidate.toMap());
    } else {
      callerCandidatesCollection.add(iceCandidate.toMap());
    }
  }
};
pc.onIceConnectionState = (state) {
  debugPrint("OnIceConnection State:- $state");
};

pc.onAddStream = (stream) {
  debugPrint("on addStream: ${stream.id}");
  _remoteVideoRenderer.srcObject = stream;
};

return pc;

}

I've figured it out. Instead of adding the stream as a whole, you need to add each track individually. Although I'm not entirely sure why this issue is occurring, it seems like they're saying "AddStream is not available with Unified Plan SdpSemantics." Here's the solution:

Instead of:

pc.addStream(_localStream);

You should use:

if (_localStream.getAudioTracks().isNotEmpty) {
    pc.addTrack(_localStream.getAudioTracks()[0], _localStream);
}
if (_localStream.getVideoTracks().isNotEmpty) {
    pc.addTrack(_localStream.getVideoTracks()[0], _localStream);
}
