Best practice for adding and removing eventListeners?

Question

Hi,What is the best practice in regards to CPU usage and performance for dealing with eventListeners when adding and removing movieclips to the stage?1. Add the eventListeners when the mc is instantiated and leave them be until exiting the appor2. Add and remove the eventListeners as the mc is added or removed from the stage (via an addedToStage and removedFromStage listener method)I would appreciate any thoughts you could share with me. Thanks!JP

Hi JP,Its usually a best practice to remove the event listeners when they are not needed anymore.You may refer to the following article for optimizing your AIR applications:http://www.adobe.com/devnet/air/articles/10_tips_building_on_air.htmlOne more tip is to set useWeakReference parameter of addEventListener method to true. (by default, its false).This way, your event listeners can be GC'd when not in use anymore.-Neha
