我的 Android 应用程序收到有关 ANR keyDispatchingTimedOut 的错误报告。令人惊讶的是，这份报告中的堆栈跟踪不包含任何我自己的类。

我还检查了我的 onPause() 和 onResume() 方法，它们应该不需要很长时间。只是完成了一些资源清理，对于 onPause() 我希望最坏情况下的最大值为 1 秒(但完全由 必须 完成的事情导致，我会在其他地方创建内存泄漏。

我会在这里发布异常(exception)情况，可能有人知道它可能来自哪里:

最佳答案

我对此的发现(但我不太确定):当我自己的应用程序中的某些内容阻塞时间过长时，就会发生这种情况。因此，当 onPause()/onResume() 等待太长时间直到返回调用者时，可能会发生超时。

我不知道的是:这个超时是多长时间，意味着一个应用程序可以拥有这些方法多长时间来执行一些内部任务......
