推荐答案

这实际上取决于您要监视的内容.根据文档您将使用此侦听器侦听以下事件:

It really depends on what you want to monitor. According to the docs you'll use this listener to listen to events on:

• 注册收听者之后
• 用户登录时
• 当前用户退出时
• 当前用户更改时

在活动中，您需要了解那些事情，您应该注册侦听器.但是根据我的经验，您只需要在登录活动中进行注册即可.

In the activities you need to know those things you should register the listener. But in my experience you'll need register it only in the login activity.
