Explain life cycle of Android Appllication ?

An activity is usually a single screen that the user sees on the device at one time.

An application typically has multiple activities, and the user flips back and forth

among them. As such, activities are the most visible part of your application.Activity

Manager is responsible for creating, destroying, and managing activities. For example,

when the user starts an application for the first time, the Activity Manager will create

its activity and put it onto the screen. Later, when the user switches screens, the Activity

Manager will move that previous activity to a holding place. This way, if the user wants to

go back to an older activity, it can be started more quickly. Older activities that the user

hasn’t used in a while will be destroyed in order to free more space for the currently active

one. This mechanism is designed to help improve the speed of the user interface and thus

improve the overall user experience.
