在Android P Behavior Changes看到以下改動(dòng)

FLAG_ACTIVITY_NEW_TASK requirement is now enforced
With Android P, you cannot start an activity from a non-activity context unless you pass the intent flag FLAG_ACTIVITY_NEW_TASK. If you attempt to start an activity without passing this flag, the activity does not start, and the system prints a message to the log.

Note: The flag requirement has always been the intended behavior, and was enforced before Android N. A bug in Android N temporarily kept the flag requirement from being enforced.

我想問(wèn)一下，是什么bug導(dǎo)致Android N中阻止強(qiáng)制在非Activity Context中啟動(dòng)activity中加FLAG_ACTIVITY_NEW_TASK?

似乎目前只找到修改源，知道bug id，但是不知道如何由此找出詳細(xì)的bug。

再追加：疑似問(wèn)題鏈接，但是我查看時(shí)訪問(wèn)被拒絕。
