rxjava: Can I use retry() but with delay?

Question

I am using rxjava in my Android app to handle network requests asynchronously. Now I would like to retry a failed network request only after a certain time has passed.

in the event when you need to print out the retry count, you can use the example provided in Rxjava's wiki page https://github.com/ReactiveX/RxJava/wiki/Error-Handling-Operators

observable.retryWhen(errors ->
    // Count and increment the number of errors.
    errors.map(error -> 1).scan((i, j) -> i + j)  
       .doOnNext(errorCount -> System.out.println(" -> query errors #: " + errorCount))
       // Limit the maximum number of retries.
       .takeWhile(errorCount -> errorCount < retryCounts)   
       // Signal resubscribe event after some delay.
       .flatMapSingle(errorCount -> Single.timer(errorCount, TimeUnit.SECONDS));
