JarCastingJavaWebsocketClient also for Android
JavaWebsocketClient is library is simple library for Websocket connection in rx for java and Android. It is designed to be fast and fault tolerant.
Currently we use okhttp3 for websocket connection because okhttp3 is simple and well tested solution.

Reactive example
How to connect to server:
final Request request = new Request.Builder()
.get()
.url("ws://10.10.0.2:8080/ws")
.build();
final Subscription subscribe = new RxWebSockets(new OkHttpClient(), request)
.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 subscription = new RxWebSockets(newWebSocket, request)
.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);
subscription.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 Request request = new Request.Builder()
.get()
.url("ws://10.10.0.2:8080/ws")
.build();
final RxWebSockets rxWebSockets = new RxWebSockets(new OkHttpClient(), request)
final ObjectSerializer serializer = new GsonObjectSerializer(new Gson(), Message.class)
final RxObjectWebSockets webSockets = new RxObjectWebSockets(rxWebSockets), serializer);
final Subscription subscription = webSockets.webSocketObservable()
.compose(MoreObservables.filterAndMap(RxObjectEventMessage.class))
.compose(RxObjectEventMessage.filterAndMap(YourMessage.class))
.subscribe(new Action1<YourMessage>() {
@Override
public void call(YourMessage yourMessage) {
System.out.println("your message: " + yourMessage.response);
}
});
Thread.sleep(1000);
subscription.unsubscribe();
Run example from gradle
To run example first run websocket server, than update url to your host in:
./gradlew :websockets-rxjava-example:installDebug
How to add to your project
to your gradle file:
repositories {
maven { url "https://jitpack.io" }
}
dependencies {
// snapshot version
compile 'com.github.jacek-marchwicki:JavaWebsocketClient:master-SNAPSHOT'
// or use specific version
compile 'com.github.jacek-marchwicki:JavaWebsocketClient:<look-on-release-tab>'
}
