Question

大家。我遇到了一个令人担忧的ANR问题。

在Log中，我的ActivityA启动ActivityB，然后ActivityA转到onPause（）和onStop（）方法。在onStop（）完成大约10秒后，ActivityManagerService打印出：

Activity stop timeout for ActivityRecord{ActivityA}
Activity reported stop, but no longer stopping: ActivityRecord{ActivityA}

然后我的ActivityA会被切片很长一段时间。如果我在此期间输入了某些内容，则会显示ANR对话框。

我确信ActivityA每次都会在onStop（）方法的最后一行打印消息。所以onStop（）方法应该已经完成了。

为什么ActivityManagerService仍会打印这些信息？为什么ActivityA会出现ANR问题？
