Android Trace Canary 提问 #815

Closed zhengzhong1 closed 1 year ago

zhengzhong1 commented 1 year ago

问题描述： Trace Canary 中通过检测主线程MessageQueue中消息执行时长来确认当前进程是否发生ANR，前台超过2s,后台超过10s 即认为当前进程发生anr，想了解一下：这两个数值是如何测定的？

private static final long FOREGROUND_MSG_THRESHOLD = -2000; private static final long BACKGROUND_MSG_THRESHOLD = -10000;

只是经验值，在漏报和误报中取一个比较平衡的值
