没有强大的网络时，Android RactiveNetwork崩溃的应用程序

Question

我正在使用来自https://github.com/pwittchen/ReactiveNetwork的'com.github.pwittchen:reactivenetwork-rx2:3.0.3'

这是我的代码

    @SuppressLint("CheckResult")
public void checkNetworkAvailable() {
    ReactiveNetwork
            .observeInternetConnectivity()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(isConnectedToInternet -> {
                changeOnlineStatus(isConnectedToInternet ? ConnectionQuality.EXCELLENT : ConnectionQuality.POOR);

            });
}

private void changeOnlineStatus(ConnectionQuality connectionQuality) {
    if (connectionQuality == ConnectionQuality.EXCELLENT) {
        // do something
        if (isTrue) {
            Snackbar.make(getView(), "Internet Connected", Snackbar.LENGTH_LONG).show();
        }
    } else if (connectionQuality == ConnectionQuality.POOR) {
        // do something
        isTrue = true;
        final Snackbar snackBar = Snackbar.make(getView(), "No Internet connection", Snackbar.LENGTH_INDEFINITE);
        snackBar.setAction("DISMISS", v -> {
            // Call your action method here
            snackBar.dismiss();
        });
        snackBar.show();
    } else if (connectionQuality == ConnectionQuality.UNKNOWN) {

        isTrue = true;
        final Snackbar snackBar = Snackbar.make(getView(), "Unknown network", Snackbar.LENGTH_INDEFINITE);
        snackBar.setAction("DISMISS", v -> {
            // Call your action method here
            snackBar.dismiss();
        });
        snackBar.show();
        // do something
    }
}

我已经将android:usesCleartextTraffic="true"到应用程序清单中。

应用仍然崩溃。 有没有人在使用图书馆并面对相同的网络？

我选择该库是因为它可以测试电话是否真的可以访问互联网。

任何帮助将不胜感激。

这是错误

即使连接超时，仍然可以处理吗？ 我还注意到，只有当我的网络不稳定时，代码才会使应用崩溃，从而导致超时。

感谢ReactiveNetwork库的所有者pwittchen的快速申购。 我在rxjava使用onError方法解决了问题

    public void checkNetworkAvailable() {

    ReactiveNetwork
            .observeInternetConnectivity()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Observer<Boolean>() {
                @Override
                public void onSubscribe(final Disposable d) {
                    // this will be invoked before operation is started
                }

                @Override
                public void onNext(final Boolean isConnectedToInternet) {
                    // do your action, when you're connected to the internet
                    changeOnlineStatus(isConnectedToInternet ? ConnectionQuality.EXCELLENT : ConnectionQuality.POOR);

                }

                @Override
                public void onError(final Throwable e) {
                    // handle an error here <-----------------
                    Snackbar.make(getView(), "Network timeout!", Snackbar.LENGTH_LONG).show();
                }

                @Override
                public void onComplete() {
                    // this will be invoked when operation is completed
                }

            });
}
