我在Android应用程序中使用wasync来使用WebSocket。我在陈述以下活动时出错了。
在测试安全websocket时http://www.websocket.org/echo.htmlAndroid版Chrome在这两种情况下都很好，CCD_ 1和CCD_。
我的代码出了什么问题？
我的设备是Nexus7(2014(，安卓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：

我的应用程序具有android.permission.INTERNET、android.pPermission.ACCESS_NETWORK_STATE、android.permission.ACCESS_WIFI_STATE.权限
试试这种方法，它对我有效。我建议使用AsyncTask在后台执行与氛围相关的任务。这是安卓活动中大气的代码
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.
*/
}
});
}
});
这里的atmosphereServletPath是指向您的氛围servlet的路径。
