RxJava:尝试将错误传播到Observer.onError时发生错误 [英] RxJava: Error occurred when trying to propagate error to Observer.onError

问题描述

我在Rx库中收到一个IllegalStateException错误，并且不确切知道问题的根源在哪里，无论是RxJava还是我做错了什么.

I am getting a IllegalStateException error in the Rx Library and don't know exactly where the root of the issue is, whether it is with RxJava or something I may be doing incorrectly.

当证书固定(发生在所有服务器请求上)但似乎指向会话超时或注销并重新登录时，将发生致命崩溃.Repro步骤(大约发生25％的时间)如下:登录，打开列表项目-一直滚动到最后-注销-登录-打开应用程序-关闭应用程序->崩溃！

The fatal crash occurs when certificate pinning (occurs on all server requests) but seems to point to a session timeout or logout and back in. Repro steps (occures about 25% of the time) are as follows: login, open list item - scroll all the way end - logout - logback in - open app - close app -> Crash!

任何人都对如何防止这种情况有任何想法?我在这里 Observer.onError不一致触发

Anyone have any ideas on how to prevent this? I found a similar issue here Observer.onError firing off inconsistently

推荐答案

正在发生的事情是，您在 Subscriber 中的 onError 实现引发了未经检查的异常，该异常与可观察的合同，这将中止可观察的处理，并在 observeOn 调度程序中抛出 OnErrorFailedException .

What's happening is that your onError implementation in a Subscriber is throwing an unchecked exception which is against the Observable contract and this aborts the observable processing throwing an OnErrorFailedException in the observeOn scheduler.
