Intent
• What is Intent ?
• Intents are used as a message passing mechanism
that works both within your application and
between applications.
• You can use Intents to do the following:
– Explicitly start a particular Service or Activity using its
class name
– Start an Activity or Service to perform an action with
(or on) a particular piece of data
– Broadcast that an event has occurred
