AndroidAsync websockets无法正常工作

Question

我正在使用koush的这个AndroidSync库来创建websocket(服务器/客户端)并在两个Android设备之间传输数据.这两个设备通过wifi连接(一个是Wifi AP,另一个连接到它).在发送请求4-5秒后,我在客户端设备中收到TimeoutException.这就是我到目前为止所做的......

ServerActivity.java

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_server);

    mSockets = new ArrayList<WebSocket>();
    mAsyncHttpServer = new AsyncHttpServer();
    mWebSocketCallback = new AsyncHttpServer.WebSocketRequestCallback() {
        @Override
        public void onConnected(final WebSocket webSocket, RequestHeaders headers) {
            mSockets.add(webSocket);
            webSocket.send("Welcome Client");
            webSocket.setClosedCallback(new CompletedCallback() {
                @Override
                public void onCompleted(Exception ex) {
                    try {
                        if (ex != null)
                            Log.e("WebSocket", "Error");
                    } finally {
                        mSockets.remove(webSocket);
                    }
                }
            });
            webSocket.setStringCallback(new WebSocket.StringCallback() {
                @Override
                public void onStringAvailable(String s) {
                    Log.d("SERVERTAG",s);
                    Toast.makeText(getApplicationContext(),s,Toast.LENGTH_SHORT).show();
                }
            });
        }
    };

    mAsyncHttpServer.websocket("/",mWebSocketCallback);
    mAsyncHttpServer.listen(Utils.PORT_NUMBER);

    Button sendButton = (Button) findViewById(R.id.sendButtonS);
    sendButton.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View view) {
            for(WebSocket socket : mSockets) {
                socket.send("Server sent a string");
            }
        }
    });

}

ClientActivity.java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_client);
    mWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);

    //Resolve IP address
    int ipAddress = mWifiManager.getConnectionInfo().getIpAddress();
    String hostAddress = Formatter.formatIpAddress(ipAddress);
    hostAddress = "http://" + hostAddress + ":" +Utils.PORT_NUMBER;
    Log.d("CLIENTTAG", "address is " + hostAddress);

    mWebSocketConnectCallback = new AsyncHttpClient.WebSocketConnectCallback() {
        @Override
        public void onCompleted(Exception ex, WebSocket webSocket) {
            if (ex != null) {
                ex.printStackTrace();
                return;
            }
            webSocket.send("Hello Server");
            webSocket.setStringCallback(new WebSocket.StringCallback() {
                @Override
                public void onStringAvailable(String s) {
                    Log.d("CLIENTTAG",s);
                    Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
                }
            });
        }
    };
    mAsyncHttpClient = AsyncHttpClient.getDefaultInstance();
    mAsyncHttpClient.websocket(hostAddress, null, mWebSocketConnectCallback);

}

这是我在客户端设备中的logcat中获得的.

我之前没有真正完成套接字编程.有人可以帮帮我吗？

任何帮助表示赞赏.

我发现了这个问题，正如 @jrandaz 所说，问题出在服务器的 IP 地址上。

事实证明

WifiManager.getConnectionInfo().getIpAddress()

返回设备自己的 IP 地址，而不是其连接的 wifi 热点设备的地址。我使用的192.168.43.1是 android 中 wifi 热点的默认 IP 地址，它有效。
