E/AndroidRuntime：致命异常：RxNewThreadScheduler-42
E/AndroidRuntime: FATAL EXCEPTION: RxNewThreadScheduler-42
我几乎没有收到来自不同用户的报告，他们遇到了应用程序崩溃的问题。
老实说，我已经不知道会发生什么。
设备有一段时间未激活，例如。 40 - 60 分钟，然后出现此错误。
感谢您的任何意见或建议。

io.reactivex.exceptions.UndeliverableException 通常在您订阅源时未实现 onError 时抛出。
但它只是包装了执行的调度程序中发生的异常
您可以在跟踪的底部构造它：
Caused by: com.rabbitmq.client.MissedHeartbeatException: Heartbeat missing with heartbeat = 60 seconds\
如果您不熟悉堆栈跟踪，我建议您阅读一下，这对调试非常重要(a good answer here)
解法：
实施全局 rx 错误处理程序 (https://github.com/ReactiveX/RxJava/blob/2.x/docs/What's-different-in-2.0.md#error-handling)
// If Java 8 lambdas are supported
RxJavaPlugins.setErrorHandler(e -> { });
// If no Retrolambda or Jack
RxJavaPlugins.setErrorHandler(Functions.<Throwable>emptyConsumer());
当然这不能解决问题。如果我们忘记在某处实现 onError() 方法，这只会防止应用程序崩溃。
不过总比应用程序崩溃好:)
我几乎没有收到来自不同用户的报告，他们遇到了应用程序崩溃的问题。
老实说，我已经不知道会发生什么。
设备有一段时间未激活，例如。 40 - 60 分钟，然后出现此错误。
感谢您的任何意见或建议。
