JavaWebsocketClient also for Android

JavaWebsocketClient is library is simple library for Websocket connection for java and Android. It is designed to be fast and fault tolerant.

Content of the package

• Example websockets server python twisted server
• Imperative websocket client library websockets/
• Imperative websocket android example websockets-example/
• Rx-java websocket client library websockets-rxjava/
• Rx-java websocket android example websockets-rxjava-example/

Imperative example

Connect to server and send message on connected:

final NewWebSocket newWebSocket = new NewWebSocket(new SecureRandomProviderImpl(), new SocketProviderImpl());
final WebSocketConnection connection = newWebSocket.create(SERVER_URI, new WebSocketListener() {
    @Override
    public void onConnected() throws IOException, InterruptedException, NotConnectedException {
        connection.sendStringMessage("register");
    }
});
connection.connect();

Reactive example

How to connect to server:

final Subscription subscribe = new RxWebSockets(new NewWebSocket(), SERVER_URI)
        .webSocketObservable()
        .subscribe(new Action1<RxEvent>() {
            @Override
            public void call(RxEvent rxEvent) {
                System.out.println("Event: " + rxEvent.toString());
            }
        });
Thread.sleep(10000);
subscribe.unsubscribe();

Send message on connected:

final Subscription subscribe = new RxWebSockets(newWebSocket, SERVER_URI)
        .webSocketObservable()
        .subscribe(new Action1<RxEvent>() {
            @Override
            public void call(RxEvent rxEvent) {
                if (rxEvent instanceof RxEventConnected) {
                    Observable.just("response")
                            .compose(RxMoreObservables.sendMessage((RxEventConnected) rxEvent))
                            .subscribe();
                }
            }
        });
Thread.sleep(1000);
subscribe.unsubscribe();

For examples look:

• Android example: Activity Presenter
• Example Real tests: RxJsonWebSocketsRealTest, RxWebSocketsRealTest, SocketRealTest
• Unit test

Rx-java with json parser

class YourMessage {
    public String response;
    public String error;
}

final RxJsonWebSockets rxJsonWebSockets = new RxJsonWebSockets(new RxWebSockets(new NewWebSocket(), SERVER_URI), new GsonBuilder().create(), Message.class);
rxJsonWebSockets.webSocketObservable()
        .compose(MoreObservables.filterAndMap(RxJsonEventMessage.class))
        .compose(RxJsonEventMessage.filterAndMap(YourMessage.class))
        .subscribe(new Action1<YourMessage>() {
            @Override
            public void call(YourMessage yourMessage) {
                System.out.println("your message: " + yourMessage.response);
            }
        });

Run examples from gradle

To run example first run websocket server, than update url to your host in:

• Rx-java Activity
• Imperative Activity

Reactive (rx-java) example:

./gradlew :websockets-rxjava-example:installDebug

Imperative example:

./gradlew :websockets-example:installDebug

How to add to your project

to your gradle file:

compile "com.appunite:websockets-java:2.0.0"
compile "com.appunite:websockets-rxjava:2.0.0"
