Android core building blocks

Content Provider: are use to share data between the applications

Fragments are like parts of activity.An activity can display one or more fragments on the screen at the same time.

Service is a background process that can run for a long time
Service can be local or remote.

Intent:Intent is used to invoke components.It is mainly used to:
Start the service
Launch the activity
Display a webpage
Broadcasst a message, Dial a phone call etc.

Intent intent=new Intent(Intent.ACTION_VIEW);

An activity is a class that reprersents a single screen.It is like a frame in AWT.

A view is the UI element such as button,label,text field etc.Anything that you see is a view.


It conatins information about activities,content providers,permissions etc.

Layout – View hierarchies that control screen format and appearance of the views

Intents – Message wiring components together
