Error: None of the following functions can be called with the arguments supplied when converted to Kotlin from Java

Question

I have seen other questions here related to this error but still not able to fix. Plus I'm asking this question because unlike other questions here, I'm getting this error only when I convert the code to Kotlin from Java.

I'm using this same RxJava code in Java, it works fine. I converted to Kotlin and it gives this error -

Kotlin Compilation Error : None of the following functions can be called with the arguments supplied

var observable : Observable<Bitmap> = Observable.just(bitmap)

var observer:Observer<Bitmap> = Observer<Bitmap>() {
                fun onSubscribe(d: Disposable) {
                    disposable = d
                }
                fun onNext(orientedBitmap:Bitmap) {
                    // do something
                }
                fun onError(e:Throwable) {
                }
                fun onComplete() {

                }
            }

observable.subscribeOn(Schedulers.io())
          .observeOn(AndroidSchedulers.mainThread())

          // It shows the error here
          .subscribe(observer)

Can anyone explain what's wrong here?

Is there more information on the error? Like which following functions are listed? — tynn, May 31 '18 at 14:10
Solved it. It was a conflict in importing package. I'm also using Observer from architecture components. — Gissipi_453, May 31 '18 at 14:42

It was a conflict in importing package. I'm also using Observer from architecture components. Import Observer of both the packages, it will be solved.

So, for this -

var observer:Observer<Bitmap> = Observer<Bitmap>()

It was taking the Observer from the architecture components.

I solved it by using it like this -

var observer = object : io.reactivex.Observer<Bitmap>
