Simple RxJava WebSocketClient
dependencies {
compile 'net.hiroq:rxwsc:0.1.7'
}If you use lambda, the code will be simpler!
onResume(){
mSocketClient = new RxWebSocketClient();
mSubscription = mSocketClient.connect(Uri.parse("ws://hogehoge"))
.subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Action1<RxWebSocketClient.Event>() {
@Override
public void call(RxWebSocketClient.Event event) {
Log.d(TAG, "== onNext ==");
switch (event.getType()) {
case CONNECT:
Log.d(TAG, " CONNECT");
mSocketClient.send("test");
break;
case DISCONNECT:
Log.d(TAG, " DISCONNECT");
break;
case MESSAGE_BINARY:
Log.d(TAG, " MESSAGE_BINARY : bytes = " + event.getBytes().length);
break;
case MESSAGE_STRING:
Log.d(TAG, " MESSAGE_STRING = " + event.getString());
break;
}
}
}, new Action1<Throwable>() {
@Override
public void call(Throwable throwable) {
Log.d(TAG, "== onError ==");
throwable.printStackTrace();
}
}, new Action0() {
@Override
public void call() {
Log.d(TAG, "== onComplete ==");
}
});
}
}
onPause(){
// After this call, connection will be disconnected.
mSubscription.unsubscribe();
}
onClick(){
mSocketClient.send("This is test message");
}If you want to reconnect automatically, use retryWhen like below:
mSocketClient = new RxWebSocketClient();
mSubscription = mSocketClient.connect(Uri.parse("ws://hogehoge"))
.retryWhen(new Func1<Observable<? extends Throwable>, Observable<?>>() {
@Override
public Observable<?> call(final Observable<? extends Throwable> observable) {
return observable.flatMap(new Func1<Throwable, Observable<?>>() {
@Override
public Observable<?> call(Throwable throwable) {
// If the exception is ConnectionException,
// retry with 5 second delay.
if (throwable instanceof ConnectException) {
Log.d(TAG, "retry with delay");
return Observable.timer(5, TimeUnit.SECONDS);
}else {
// Other exceptions will be handle onError
return Observable.error(throwable);
}
}
});
}
})
.subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())You can run sample project with sample WebSocket server which is implemented in Javascript and run on Node.js.
cd sample-server
npm install
node app.js
Then run sample android app on an emulator.
If you want run the sample on a real devide, you have to change Connetion URL.
- make test
