Question

我在Android应用中使用wasync来使用WebSocket。在说明如下活动时我收到了错误。

使用Chrome for Android在http://www.websocket.org/echo.html测试安全websocket时，两种情况都可以正常运行 uri("https://echo.websocket.org")和uri("https://<my websocket server>")都不起作用。

我的代码出了什么问题？

我的设备是Nexus7（2014），Android 4.4.2。

    private Socket socket;    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_wasync_test);
        new Thread() {
            public void run() {
                AtmosphereClient client = ClientFactory.getDefault().newClient(AtmosphereClient.class);
                AtmosphereRequest.AtmosphereRequestBuilder request = client.newRequestBuilder()
                .method(Request.METHOD.GET)
                .enableProtocol(false)
                .uri("https://echo.websocket.org")
                .transport(Request.TRANSPORT.WEBSOCKET);
                socket = client.create()
                // on(MESSAGE, OPEN, CLOSE) are omitted
               .on(Event.ERROR, new Function<Object>() {
                   @Override
                   public void on(Object o) {
                       Log.e(TAG, "[wasync] onerror: " + o);
                   }
               });
               try {
                   socket.open(request.build());
               } catch (IOException e) {
               }
            }
        }.start();
    }

我得到的错误是：

试试这种方式，它对我有用。我建议使用AsyncTask在后台进行与大气相关的任务。这是Android Activity中的Atmosphere代码

AtmosphereClient client = ClientFactory.getDefault().newClient(AtmosphereClient.class);
final RequestBuilder request = client.newRequestBuilder()
                    .method(Request.METHOD.GET)
                    .uri(atmosphereServletPath)
                    .trackMessageLength(true)
                    /*
                     * code to set the default transport to Websocket
                     */
                    .transport(Request.TRANSPORT.WEBSOCKET)

                    /*
                     * code to set the fall-back transport to Long-Polling
                     */
                    .transport(Request.TRANSPORT.LONG_POLLING);

            /*
             * code to create the socket at server side using the created client
             */
            socket = client.create();

            /*
             * code to open the socket
             */
            socket.open(request.build());

            /*
             * code for Message handler
             */
            socket.on("message", new Function<YourObject>() {
                @Override
                public void on(final YourObject s) {
                    uiHandler.post(new Runnable() {
                        /*
                         * @see java.lang.Runnable#run() Here I've received the
                         * YourObject from the server
                         */
                        @Override
                        public void run() {
                            /*
                            * tasks for onMessage() method.
                            */
                        }
                    });
                }
            });

此处atmosphereServletPath是您的氛围servlet的路径。

在Android中使用wasync的WebSocket连接不起作用
