沒有強大的網絡時，Android RactiveNetwork崩潰的應用程序

Question

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

這是我的代碼

    @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
    }
}

我已經將android:usesCleartextTraffic="true"到應用程序清單中。

應用仍然崩潰。 有沒有人在使用圖書館並面對相同的網絡？

我選擇該庫是因為它可以測試電話是否真的可以訪問互聯網。

任何幫助將不勝感激。

這是錯誤

即使連接超時，仍然可以處理嗎？ 我還注意到，只有當我的網絡不穩定時，代碼才會使應用崩潰，從而導致超時。

感謝ReactiveNetwork庫的所有者pwittchen的快速申購。 我在rxjava使用onError方法解決了問題

    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
                }

            });
}
