Answer 1

In Kotlin use flattenAsFlowable:

repository.getFlowableData(id)
    .subscribeOn(Schedulers.io())
    .observeOn(Schedulers.computation())
    .toList()
    .flattenAsFlowable { it }
    .map { someMethod(it) }
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe({ },
        { onError(it) })
