RxAndroid in conjunction with RxJava 2

[programmerr47]

Hello.

Recently rxJava 2 has been released.
So currently when I try to use rxAndroid 1.2.1 with rxJava 2.0.0:

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

I'm getting an error:

observeOn(io.reactivex.Schedulers) in Observable cannot be applied to (rx.Scheduler)

I suppose it is because in rxJava 2 Schedulers was moved from rx package to io.reactivex package.

My question is, how I can use rxAndroid in conjunction with rxJava 2?

Thank you.

@programmerr47 @JakeWharton @mttkay Hello，How do I solve this problem ？

[programmerr47]

@xubuhang Hi. Simple: compile 'io.reactivex.rxjava2:rxandroid:2.0.0'
It was my mistake that I didn't search a little bit before posting this issue

Still have the same problem with io.reactivex.rxjava2:rxandroid:2.0.0. This is not solve the error observeOn(io.reactivex.Schedulers) in Observable cannot be applied to (rx.Scheduler)

@viethoa You have a wrong import - rx.Scheduler is a scheduler from rxjava1, you need to import one from io.reactivex

Still getting error io.reactivex.rxjava2:rxandroid:2.0.1. This does not solve the error observeOn(io.reactivex.Schedulers) in Observable cannot be applied to (rx.Scheduler)

You're using the wrong import for AndroidSchedulers

@JakeWharton :
import io.reactivex.android.schedulers.AndroidSchedulers;
import io.reactivex.disposables.CompositeDisposable;
import io.reactivex.schedulers.Schedulers;

These are my imports

[JakeWharton]

You have a 1.x observable and are trying to use a 2.x scheduler

Your import for Observable should be import io.reactivex.Observable; not import rx.Observable;

[replyashu]

@JakeWharton apology, it was import in another file, which was being reflected here. Thanks for the prompt reply. And hats off to your contribution in RxJava and other libraries

@JakeWharton @bs2015 @dimsuz
If I choose to import io.reactivex.Observable; then I have a problem with Subscription

[akarnokd]

@ku4irka In 2.x, the Observer requires Disposable and Disposables is the utility class to create some default instances.

[ku4irka]

@akarnokd please can show the example code, because i do not fully can understand you

[akarnokd]

import io.reactivex.*;
import io.reactivex.disposables.*;

Disposable disposable = Disposables.empty();

disposable = io.reactivex.Observable.just(1).subscribeWith(new DisposableObserver<Integer>() {
    // ...
});

[ku4irka]

@akarnokd Thanks for the advice
have a good day :)

[trinadhkoya]

re check the import !! it should be as @replyashu said.

[mastermj94]

i had this problem too and my mistake , i was using wrong imports for rxjava2 so i changed my imports to:
import io.reactivex.Observer;
import io.reactivex.android.schedulers.AndroidSchedulers;
import io.reactivex.disposables.Disposable;
import io.reactivex.schedulers.Schedulers;
i hope this can help.
