使用OkHttp和RxJava2的NetworkOnMainThreadException [英] NetworkOnMainThreadException using OkHttp with RxJava2

问题描述

我正在尝试学习Rxjava2.我在使用okHttp进行网络通话时遇到了一个问题，即NetworkOnMainThreadException.我只需要使用okHttp库.

I am trying to learn Rxjava2. I am facing a problem i.e, NetworkOnMainThreadException during network call using okHttp. I have to use only okHttp libary.

这是我编写用于调用Login API的RxJava2代码的方法.

This is my method where I have written the code of RxJava2 for calling Login API.

@Override
public void onServerLoginClick(LoginRequest.ServerLoginRequest serverLoginRequest) {
    HttpParamObject httpParamObject = ApiGenerator.onServerLogin(serverLoginRequest);
    Service service = ServiceFactory.getInstance(activity, AppConstants.TASKCODES.LOGIN);

    try {
        Observable.just(service.getData(httpParamObject))
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe((Consumer<? super Object>) getObserver());
    } catch (JSONException | IOException | RestException | SQLException e) {
        e.printStackTrace();
    }
}

private Subscriber<LoginResponse> getObserver(){
    return new Subscriber<LoginResponse>() {
        @Override
        public void onSubscribe(Subscription s) {

        }

        @Override
        public void onNext(LoginResponse loginResponse) {
            getUiView().showToast(loginResponse.getMessage());
        }

        @Override
        public void onError(Throwable t) {

        }

        @Override
        public void onComplete() {

        }
    };

}

我做错什么了吗?请帮助我.

Am I doing something wrong or missing anything? Please help me.

推荐答案

您正在主线程中调用service.getData(httpParamObject)，并将结果传递给Observable.just.因此，您的subscribeOn没有任何作用.

You're calling service.getData(httpParamObject) in the main thread and passing that result to Observable.just. So your subscribeOn has no effect.

检查 Observable.create 的文档，并使用它代替Observable.just

Check the documentation of Observable.create and use it instead of Observable.just
