A very simple bare-minimum WebSocket and Socket.IO client for Android.

The hybi parser is based on code from the [faye project](https://github.com/faye/faye-websocket-node). Faye is Copyright (c) 2009-2012 James Coglan. Many thanks for the great open-source library!

The hybi parser was ported from JavaScript to Java by [Eric Butler](https://twitter.com/codebutler) <eric@codebutler.com>.

## WebSocket Usage

```java
List<BasicNameValuePair> extraHeaders = Arrays.asList(
    new BasicNameValuePair("Cookie", "session=abcd")
);

WebSocketClient client = new WebSocketClient(URI.create("wss://irccloud.com"), new WebSocketClient.Listener() {
    @Override
    public void onConnect() {
        Log.d(TAG, "Connected!");
    }

    @Override
    public void onMessage(String message) {
        Log.d(TAG, String.format("Got string message! %s", message));
    }

    @Override
    public void onMessage(byte[] data) {
        Log.d(TAG, String.format("Got binary message! %s", toHexString(data)));
    }

    @Override
    public void onDisconnect(int code, String reason) {
        Log.d(TAG, String.format("Disconnected! Code: %d Reason: %s", code, reason));
    }

    @Override
    public void onError(Exception error) {
        Log.e(TAG, "Error!", error);
    }
}, extraHeaders);

client.connect();

// Later… 
client.send("hello!");
client.send(new byte[] { 0xDE, 0xAD, 0xBE, 0xEF });
client.disconnect();
```

## Socket.IO Usage

```java
SocketIOClient client = new SocketIOClient(URI.create("wss://example.com"), new SocketIOClient.Handler() {
    @Override
    public void onConnect() {
        Log.d(TAG, "Connected!");
    }

    @Override
    public void on(String event, JSONArray arguments) {
        Log.d(TAG, String.format("Got event %s: %s", event, arguments.toString()));
    }
    
    @Override
    public void onJSON(JSONObject json) {
    	try {
    		Log.d(TAG, String.format("Got JSON Object: %s", json.toString()));
    	} catch(JSONException e) {
    	}
    }

    @Override
    public void onMessage(String message) {
    	Log.d(TAG, String.format("Got message: %s", message));
    }

    @Override
    public void onDisconnect(int code, String reason) {
        Log.d(TAG, String.format("Disconnected! Code: %d Reason: %s", code, reason));
    }

    @Override
    public void onError(Exception error) {
        Log.e(TAG, "Error!", error);
    }
});

client.connect();

// Later… 
client.emit("Message"); //Message
JSONArray arguments = new JSONArray();
arguments.put("first argument");
JSONObject second = new JSONObject();
second.put("dictionary", true);
client.emit(second); //JSON Message
arguments.put(second);
client.emit("hello", arguments); //Event
client.disconnect();
```
