Question

我试图创建一个聊天应用程序，所以我创建了一个简单的原型。后端服务器使用flask-socketio框架。我使用了这份文档https://flask-socketio.readthedocs.io/en/latest/，下面是烧瓶后端的代码：

from flask import Flask
from flask_socketio import SocketIO, send

app = Flask(__name__)
app.config['SECRET_KEY'] = 'mysecret'
socketio = SocketIO(app, cors_allowed_origins="*")

@app.route('/main')
def test():
    return 'Test'

@socketio.on('message', namespace = '/nice')
def handleMessage(msg):
    print('Message: ' + msg)
    send(msg, broadcast = True)

if __name__ == '__main__':
    socketio.run(app, host = '0.0.0.0', port = 5000, debug = True)

要将后端与android连接，我使用了Java socketIO文档：https://github.com/socketio/socket.io-client-java由于某种原因，当我使用emuator时一切正常，但是当我使用手机时，什么也没发生。这是Android Studio 主要活动（唯一的活动）

public class MainActivity extends AppCompatActivity {


    private Button button;
    private TextView text;
    private EditText edit;
    private String message;
    private String link = "http://192.168.0.106:5000/nice";
    private io.socket.client.Socket mSocket;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = findViewById(R.id.button);
        text =  findViewById(R.id.text);
        edit =  findViewById(R.id.edit);

        Server server = new Server(link);
        new Thread(server).start();

        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                String message = edit.getText().toString().trim();
                if (!message.isEmpty()) {
                    mSocket.emit("message", message);
                }
            }
        });

    }

    private class Server implements Runnable{

        private String uri;

        public Server(String uri){
            this.uri = uri;
        }

        @Override
        public void run() {
            try {
                mSocket = IO.socket(uri);
                mSocket.connect();
                mSocket.open();
                Log.d("myTag", "Pavyko");
            } catch (URISyntaxException e) {
                Log.d("myTag", e.getMessage());
            }

            mSocket.on("message", new Emitter.Listener() {
                @Override
                public void call(Object... args) {
                    message = args[0].toString();
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            text.setText(message);
                        }
                    });
                }
            });
        }
    }
}

清单有：

<uses-permission android:name="android.permission.INTERNET"/>

和成绩：

implementation ('io.socket:socket.io-client:1.0.0') {
    // excluding org.json which is provided by Android
    exclude group: 'org.json', module: 'json'
}

没有错误，所以我真的不知道该怎么办...

Socket.io在Android手机上不起作用，但在模拟器上起作用
