带rxJava2和改装的UndeliverableException
带rxJava2和改装的UndeliverableException
提问于 2017-09-19 03:06:00
有一个例外，它反复出现在我的应用程序的Crashlytics(Fabric)上。我使用rxjava2进行http调用。
这就是crashlytics日志中的所有内容(如下所示)。会非常感谢你的帮助的/insights。

如果您没有向订阅者或观察者提供可抛出的lambda ..Rxjava无法捕获这些异常。因此，简单的解决方案是每当订阅Observable或其他Rxjava类型时，覆盖onError()方法，并根据情况处理它们。
compositeDisposable.add(Observable.just("start")
.doOnNext(ignored -> loadingIndicator.onNext(true))
.flatMap(ignored -> repository.getAndroidDev())
.subscribe(posts::onNext, throwable -> Timber.e(throwable))); //second lambda is the solution, at lease you can log the errors, if you're not willing to handle them页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
