5. Simple Activity Classes

There are four major types of component classes in any Android application:

• Activities: Much like a Form for a web page, activities display a user interface for the purpose of performing a single task. An example of an Activity class would be one which displays a Login Screen to the user.
  
  
• Services: These differ from Activities in that they have no user interface. Services run in the background to perform some sort of task. An example of a Service class would be one which fetches your email from a web server.
  
  
• Broadcast Receivers: The sole purpose of components of this type is to receive and react to broadcast announcements which are either initiated by system code or other applications. If you've ever done any work with Java Swing, you can think of these like Event Handlers. For example, a broadcast announcement may be made to signal that a WiFi connection has been established. A Broadcast Receiver for an email application listening for that broadcast may then trigger a Service to fetch your email.
  
  
• Content Providers: Components of this type function to provide data from their application to other applications. Components of this type would allow an email application to use the phone's existing contact list application for looking up and retrieving email address.
