在安卓系统上实现Kaazing EventSource

Question

我正在编写一个安卓应用程序，需要EventSource来接收服务器发送的事件。我正在尝试创建SseEventSourceFactory对象，但在创建时收到NoSuchElement异常。我该如何解决这个问题呢？

下面是我的代码：

// Import java.net classes
import java.net.URI;
import java.net.URL;

// Import EventSource API classes
import com.kaazing.net.sse.SseEventReader;
import com.kaazing.net.sse.SseEventSource;
import com.kaazing.net.sse.SseEventSourceFactory;
import com.kaazing.net.sse.SseEventType;

try {
            // Create Event Source factory( Exception thrown here
            SseEventSourceFactory factory = SseEventSourceFactory.createEventSourceFactory();

            // Create a target location using the java.net.URI create() method
            final SseEventSource es = factory.createEventSource(URI.create("http://cak9c.com/sse.php"));

            // Connect to the event source.
            es.connect();

            final Object o = this;
            Thread sseEventReaderThread = new Thread() {
                public void run() {
                    try {
                        SseEventReader reader = es.getEventReader(); // Receive event stream

                        SseEventType type = null;
                        while ((type = reader.next()) != SseEventType.EOS) { // Wait until type is DATA
                            switch (type) {
                                case DATA:
                                    // Return the payload of the last received event
                                    System.out.println(reader.getData());
                                    break;
                                case EMPTY:
                                    System.out.println("no data");
                                    break;
                            }
                        }

                    }
                    catch (Exception ex) {
                        System.out.println(ex.getMessage());
                    }
                }
            };
            es.close();
        }
        catch(Exception e)
        {
            System.out.println(e.getMessage());
            Toast.makeText(this, e.getLocalizedMessage() + ": " + e.getMessage(), Toast.LENGTH_LONG).show();
        }
