Life cycle of activity during lock screen

If the Activity tab in the manifest file does not specify the direction android:screenOrientation="landscape" of the screen
The default is the vertical screen, activity life cycle in the lock screen and open the screen when it is normal:

However, if you do not specify the orientation of the screen under the Activity tab in the manifest file android:screenOrientation="landscape" , the activity will re-create

The life cycle of the lock screen is:

Destroyed and then re-created, and then in a paused state.

The life cycle when the screen is turned on is:

Destroyed again, rebuilt.

So the screen after the lock screen will be destroyed two times, rebuilt two times.

The workarounds are:
Configure Under Activity tab in the manifest file
android:configChanges="orientation|screenSize"。

Remember that configuring under the Application tab is not working.
