Android 操作系统关闭 - 错误报告 WTF

Question

我让我的应用程序正常工作了几个小时，然后我突然收到这条消息，手机关机了:

在 logcat 中重复了大约 500 行。我也不知道那是什么，因为我的应用程序看起来没有参与，并且在发生 fatal error 时没有做任何事情。

Answer 1

DeadObjectException 在以下情况下抛出:

The object you are calling has died, because its hosting process no longer exists.

您是否绑定(bind)到应用中的服务？文档说:

You should always trap DeadObjectException exceptions, which are thrown when the connection has broken. This is the only exception thrown by remote methods.

在此特定上下文中，“连接”指的是服务连接。
