Turn: Android--Activitylifecyclecallbacks

The use of an uncommon class, named Activitylifecyclecallbacks

Usually there is a lot of activity in a project, although each activity has its own independent callback method. But Activitylifecyclecallbacks comes in handy if you need to do some uniform operations on all your activity.

It is for all activity in the project.

在自定义的Application中的onCreate()方法，或在Application的无参构造方法内，调用 Application.registerActivityLifecycleCallbacks()方法，并实现 ActivityLifecycleCallbacks接口；

This method must be called in a api>14 development environment.

Of course, we developers can create a callback method themselves, and create a beseactivity base class .... There is a detailed description in the above brother's article.
