Android-Socket.IO客户端未收到自定义事件

Question

我在实现Android socket.io客户端时遇到问题。基本上，我有一个Angular Web应用程序和一个Android应用程序，应该使用套接字服务器相互通信。这是用于处理套接字的Android代码：

private Socket mSocket;
private String mRoomId;
private int mClientId = -1;
private int mReceiverId = -1;

private Emitter.Listener mMessageListener = args -> {
    JSONObject data = (JSONObject) args[0];
    Log.i(TAG, "Message: " + data.toString());
    try {
        RTCMessage message = new RTCMessage(data);
        if(mClientId == message.receiver()) {
            // Message was sent to this client
            handleSignalingMessage(message);
        }
    } catch (JSONException ex) {
        ex.printStackTrace(); // TODO Handle
        if(mListener != null) mListener.onChannelError(ex.getLocalizedMessage());
    }
};

private Emitter.Listener mPeerConnectedListener = args -> {
    JSONObject data = (JSONObject) args[0];
    Log.i(TAG, "Peer connected: " + data.toString());
    try {
        if (data.has("id")) {
            mReceiverId = data.getInt("id");
            if(mListener != null) {
                mListener.onRemoteConnected(mReceiverId);
            }
        } else {
            // Connection without receiver id, this is an error
        }
    } catch (JSONException ex) {
        ex.printStackTrace(); // TODO Handle
        if(mListener != null) mListener.onChannelError(ex.getLocalizedMessage());
    }
};

private Emitter.Listener mPeerDisconnectedListener = args -> {
    JSONObject data = (JSONObject) args[0];
    Log.i(TAG, "Peer disconnected: " + data.toString());
    mReceiverId = -1;
};

public void setListener(@NonNull RTCClient.SignalingEvents listener) {
    this.mListener = listener;
}

public void connect(String url) {
    try {
        Log.i(TAG, "Connecting to WebSocket");
        IO.Options opts = new IO.Options();
        opts.forceNew = false;
        mSocket = IO.socket(url, opts);
        // Must be called AFTER bindEvents
        mSocket.connect();
        bindEvents(mSocket);
        createRoom();
    } catch (URISyntaxException e) {
        e.printStackTrace(); // TODO Handle
    }
}

public void disconnect() {
    if(mSocket != null) {
        Log.i(TAG, "Disconnecting from WebSocket");
        mSocket.disconnect();
    } else {
        Log.d(TAG, "Tried to close uninitialized socket");
    }
}

private void bindEvents(Socket socket) {
    Log.i(TAG, "Binding socket events");
    socket.on(Socket.EVENT_CONNECT, args -> {
        Log.i(TAG, "Connected to socket");
    });
    socket.on("msg", mMessageListener);
    socket.on("peer.connected", mPeerConnectedListener);
    socket.on("peer.disconnected", mPeerDisconnectedListener);
}

我会注意到，经过一些研究，似乎Web应用程序正确发送了消息，并且两者都成功加入了同一个会议室。套接字服务器还成功转发了“ peer.connected”消息，但Android客户端不处理它（以及“ msg”和“ peer.disconnected”消息，但它确实正确接收了Socket.EVENT_CONNECT消息）< / p>
