components of android app development lifecycle

In general, there are four different android app components. Each type serves a distinct purpose and has a distinct life cycle that defines how the component is created and destroyed. The components are: Activities - an activity represents a single screen with a user interface, Services - a service is a component that runs in the background to perform long-running operations or to perform work for remote processes, Content Providers - a content provider manages a shared set of android app data, Broadcast receivers - a broadcast receiver is a component that responds to system-wide broadcast announcements.
