我收到有关ANR keyDispatchingTimedOut的Android-App错误报告。令人惊讶的是，此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，它们不需要很长时间。只有一些资源的清理工作，对于onPause（）我预计最坏情况下的最大值为1秒（但完全由有的东西完成，在其他地方我创造内存泄漏。
我会在这里发布例外情况，可能有人知道它可能来自哪里：

答案 0 :(得分：0)
我发现了什么（但我不太确定）：当我自己的App中的某些东西阻塞了太长时间时会发生这种情况。因此，当onPause（）/ onResume（）等待太长时间，直到它们返回调用者时，可能会发生超时。
我不确切知道：这个超时多长时间，意味着应用程序可以拥有这些方法执行某些内部任务多长时间......
