 The **WindowAnimationManager** module provides APIs to listen for application start/exit events and window minimization/maximization events and associate animations with these events.
 
 >  **NOTE**

 >  The APIs of this module are supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
