            .subscribe(tick -> Log.d(TAG, "tick = &qu         


        

Answer 1

You can use takeWhile and loop until conditions is true

Observable.interval(1, TimeUnit.SECONDS)
        .takeWhile {
            Log.i(TAG, " time " + it)
            it != 30L
        }
        .subscribe(object : Observer {
            override fun onComplete() {
                Log.i(TAG, "onComplete " + format.format(System.currentTimeMillis()))
            }

            override fun onSubscribe(d: Disposable) {
                Log.i(TAG, "onSubscribe " + format.format(System.currentTimeMillis()))
            }

            override fun onNext(t: Long) {
                Log.i(TAG, "onNext " + format.format(System.currentTimeMillis()))
            }

            override fun onError(e: Throwable) {
                Log.i(TAG, "onError")
                e.printStackTrace()
            }

        });
