Faye client ported from Objective-C to Java by Saul Howard saulpower1@gmail.com.

Usage

Here is a some sample code to create the client as a service in Android:

    public class WebSocketService extends IntentService implements FayeListener {

        public final String TAG = this.getClass().getSimpleName();

        FayeClient mClient;

        public WebSocketService() {
            super("WebSocketService");
        }

        @Override
        protected void onHandleIntent(Intent intent) {

            // SSL bug in pre-Gingerbread devices makes websockets currently unusable
            if (android.os.Build.VERSION.SDK_INT <= 8) return;

            Log.i(TAG, "Starting Web Socket");

            try {

                String baseUrl = Preferences.getString(Preferences.KEY_FAYE_HOST, DebugActivity.PROD_FAYE_HOST);

                URI uri = URI.create(String.format("wss://%s:443/events", baseUrl));
                String channel = String.format("/%s/**", User.getCurrentUser().getUserId());

                JSONObject ext = new JSONObject();
                ext.put("authToken", User.getCurrentUser().getAuthorizationToken());

                mClient = new FayeClient(uri, channel);
                mClient.setFayeListener(this);
                mClient.connectToServer(ext);

            } catch (JSONException ex) {}
        }

        @Override
        public void onCreate() {
            super.onCreate();
        }

        @Override
        public void onStart(Intent intent, int startId) {
            super.onStart(intent, startId);
        }

        @Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            return super.onStartCommand(intent, flags, startId);
        }

        @Override
        public void connectedToServer() {
            Log.i(TAG, "Connected to Server");
        }

        @Override
        public void disconnectedFromServer() {
            Log.i(TAG, "Disonnected to Server");
        }

        @Override
        public void subscribedToChannel(String subscription) {
            Log.i(TAG, String.format("Subscribed to channel %s on Faye", subscription));
        }

        @Override
        public void subscriptionFailedWithError(String error) {
            Log.i(TAG, String.format("Subscription failed with error: %s", error));
        }

        @Override
        public void messageReceived(JSONObject json) {
            Log.i(TAG, String.format("Received message %s", json.toString()));
        }
    }

Add the following service to your AndroidManifest.xml file:

    <service android:name=".shared.Services.WebSocketService" />

Finally, to start the service simply call:

    Intent intent = new Intent(this, WebSocketService.class);
    startService(intent);
