Java 当没有强大的网络时，Android会导致网络崩溃

我使用的是来自的

'com.github.pwitchen:reactivenetwork-rx2:3.0.3'

这是我的密码

    @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
    }
}

我已经在应用程序清单中添加了

android:usesCleartextTraffic=“true”

应用程序仍在崩溃。是否有人使用图书馆并面对相同的网络

我选择图书馆是因为它测试手机是否真的可以上网

任何帮助都将不胜感激

这里是错误

即使连接超时，是否仍要处理此问题？

我还注意到，只有当我的网络不稳定时，代码才会使应用程序崩溃，从而导致超时。

多亏了ReactiveNetwork library的所有者pWitchen的快速响应。我在

rxjava

    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
