In android i use Timer to execute task that repeats every 5 seconds and starts after 1 second in this way:

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new TimerTask() {
        @Override
        public void run() {
            // Here is the repeated task
        }
    }, /*Start after*/1000, /*Repeats every*/5000);

    // here i stop the timer
    timer.cancel();

this timer will repeat Until i call timer.cancel()

I am learning RxJava with RxAndroid extension

So i found this code on internet, i tried it and it doesnt repeat:

Observable.timer(3000, TimeUnit.MILLISECONDS)
    .subscribeOn(Schedulers.newThread())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(new Action1<Long>() {
        @Override
        public void call(Long aLong) {
             // here is the task that should repeat
        }
    });

so what is the alternative for the android Timer in RxJava.

timer operator emits an item after a specified delay then completes. I think you looking for the interval operator.

Subscription subscription = Observable.interval(1000, 5000, TimeUnit.MILLISECONDS)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Action1<Long>() {
                public void call(Long aLong) {
                    // here is the task that should repeat
                }
            });

if you want to stop it you just call unsubscribe on the subscription:

subscription.unsubscribe()

Best way to repeat an observable every minute rxjava, if you want to finish this operation at any time call disposable.dispose() RxJava timer that repeats forever, and can be restarted and stopped , So i found this� One more very important thing to notice is that all the Operators Timer, Delay, and Interval run on Schedulers.computation(). So we do not need to worry about that. This way we can use RxJava Timer, Delay, and Interval Operators to solve the interesting problem. Find the complete project here and learn RxJava.

Call Observable.repeat() method to repeat

Disposable disposable = Observable.timer(3000, TimeUnit.MILLISECONDS)
.subscribeOn(Schedulers.newThread())
.repeat()
.observeOn(AndroidSchedulers.mainThread())
.subscribe();

If you want to stop it call disposable.dispose()

Understanding RxJava Timer, Delay, and Interval Operators, Here the task will be done again and again after 2 seconds of interval. One thing to notice: It will keep going on forever. How to stop that? There� delay() With the help of the delay() operator emissions can be shifted forward in time.. import io.reactivex.Observable; import java.util.concurrent.TimeUnit; public

KOTLIN way

Observable.timer(5000, TimeUnit.MILLISECONDS)
            .repeat() //to perform your task every 5 seconds
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe {
                Log.d("ComingHere", "Inside_Timer")
            }

Observable, RxJava timer that repeats forever, and can be restarted and stopped at anytime. 由丶灬走出姿态 提交于2019-12-04 23:14:44. In android i use Timer to execute� Whenever we have the use-case in which we want to do the task after a particular span of time, we can use the Timer Operator. Now, let's learn the Delay Operator of RxJava Delay operator shift the emissions from an Observable forward in time by a particular amount.

RxJava's repeatWhen and retryWhen, explained, Creates a new Observable, that will execute the specified function when an Observer and emits ever increasing numbers after each period of time thereafter. of closing Observables to determine when to close, emit, and reset the buffer. Returns an Observable that repeats the stream of items emitted by the source� When developing an app, specially if we are dealing with requests to network resources, we might want to configure some timeouts, so if the server takes so long to process a request, we can take specific actions, instead of hang forever. RxJava provides an operator called timeout that, according to the docs, “allows you to abort an Observable

[PDF] ATmega88/ATmega168, The input is an Observable<Throwable> that emits anytime the source Since delay waits some time before emitting onNext() , this has the effect emits an onCompleted without ever subscribing to the original Observable. You can repeat/retry any number of times, so you need to return an Observable. Teams. Q&A for Work.

[PDF] ATmega16U4/32U4 Datasheet, This allows the clock to restart and become stable after having been stopped. The wake-up might lead to an eternal loop of time-out resets. To avoid USART Rx complete. 20. 0x013 This feature allows the OCR1A I/O location to be written anytime. REPEATED START, the bus is considered busy until the next STOP. However, this can take arbitrarily long to occur. By default, the task execution thread does not run as a daemon thread, so it is capable of keeping an application from terminating. If a caller wants to terminate a timer's task execution thread rapidly, the caller should invoke the timer's cancel method.

Comments
  • I just started learning RxJava and I'd like to know which one of those (Timer and RxJava) would be better in that approach? I mean related to performance and developing speed
  • Observable.timer will only fire once and then completes
  • You don't need .subscribeOn(Schedulers.io()) to start in background because Observable.interval emits on Schedulers.computation() by default.
  • in RX 2 instead of Action1 you should use Consumer
  • Can you tell how to reuse this timer..calling subscribe again will perform the same task twice in TimeUnit intervals.
  • @AkshayMahajan use publish() operator for that (possible with replay(1) depending on your case)
