app没有没有卡死，但它在启动过程中的 窗口焦点切换需要时间。Monkey 在这个极短的窗口期内
（如从 18:53:23.026 开始 resume 到 18:53:23.340 收到事件之间），过快地发送了输入事件。
系统尝试将事件分发给该 Activity，但由于窗口尚未正式“就位”并获得焦点，导致分发失败，并触发了 5 秒的 ANR 计时器，最终超时。
这不是应用本身的严重缺陷，而是自动化压力测试（Monkey）在系统调度边界条件下的偶发现象
ANR 是由 Monkey 快速发送输入事件与应用启动（获取焦点）耗时较长两者叠加导致的。
在正常的用户操作流程中，用户会给应用足够的启动时间，不会在启动 Activity 尚未获得焦点时的极短时间内触发输入事件。
