数据不会使用socket.io库从android客户端发送到服务器

我正在使用socket.io库创建聊天应用程序。指向库的github链接是com.github.nkzawa:socket.io客户端：0.3.0。我想添加用户添加频道的功能。为此，我将发送通道名称和描述，但问题是数据不会发送到服务器。我已完成调试，但无法检测问题出在哪里。代码如下所示： HomeActivity.java

public class HomeActivity extends AppCompatActivity implements AlertDialogueBoxInterface {

private Socket mSocket;
private Boolean isConnected = true;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
RoundTableApplication app = (RoundTableApplication) this.getApplication();
    mSocket = app.getSocket();
    mSocket.on(Socket.EVENT_CONNECT,onConnect);
    mSocket.on(Socket.EVENT_DISCONNECT,onDisconnect);
    mSocket.on(Socket.EVENT_CONNECT_ERROR, onConnectError);
    mSocket.on(Socket.EVENT_CONNECT_TIMEOUT, onConnectError);
    mSocket.connect();
 private Emitter.Listener onConnect = new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if(!isConnected) {
                    if(null!=channelName)
                        mSocket.emit("add channel", channelName, channelDescription);
                    Toast.makeText(getApplicationContext(),
                            "Connected", Toast.LENGTH_LONG).show();
                    isConnected = true;
                }
            }
        });
    }
};

    }

@Override
public void sendChannel(ArrayList<String> channelList) {
    channelName = channelList.get(0);

如果有人能在这方面帮我的话，我对安卓系统还是新手。提前感谢您的RoundTableApplication.java

替换：

private Socket mSocket;

mSocket.emit("add channel", channelName, channelDescription);

与

之后，在HomeActivity.java中删除：

private Socket mSocket;

将HomeActivity.java中的mSocket替换为：

RoundTableApplication.mSocket

e、 国际贸易

mSocket.connect();

使用

并在建立连接后使用emit方法—您正在onConnect中使用它。连接套接字后使用，并且需要发射器侦听器接口来处理发出的事件。Emit订阅事件，但要处理响应，您需要我在代码中找不到的发射器侦听器

替换：

private Socket mSocket;

mSocket.emit("add channel", channelName, channelDescription);

与：

在上面的语句中，listenerMethod是一种描述当您得到响应时要做什么的方法

按照以下链接熟悉socket.io：
