Question

我正在使用大量网络调用的大型代码库。它目前适用于Retrofit 1.9和RxJava 1.x.但是，我们正试图去RxJava 2.x。

我目前在RxJava 2代码上获得NetworkOnMainThreadException。我使用的是RxJava 2.x和Retrofit 1.9。计划是稍后转到Retrofit 2.x.但是，就目前而言，我们需要使用RxJava 2 + Retrofit 1.9。

有问题的代码是：

observable
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribeWith(new DisposableObserver<Void>() {
    @Override
    public void onNext(Void response) {
        if (listener != null) {
            listener.onSuccess(response);
        }   
    }   

    @Override
    public void onError(Throwable e) {
        if (listener != null) {
            listener.onError(e);
        }   
    }   

    @Override
    public void onComplete() {
        //do nothing for now 
    }   
});

当我告诉subscribeOn(Schedulers.io())时，网络操作如何在UI线程上结束？

编辑：根据请求在这里进行堆栈跟踪。我将文件名通用化，因为我不允许透露这些细节...

使用RxJava 2 + Retrofit 1.9的NetworkOnMainThreadException
