Intent Overview

The core components of an Android application (its activities, services, and broadcast receivers) are activated
by intents. An intent is a bundle of information (an Intent object) describing a desired action — including the
data to be acted upon, the category of component that should perform the action, and other pertinent
instructions. Android locates an appropriate component to respond to the intent, launches a new instance of
the component if one is needed, and passes it the Intent object.
Components advertise their capabilities, the kinds of intents they can respond to, through intent filters. Since
the system must learn which intents a component can handle before it launches the component, intent filters
are specified in the manifest as <intent-filter> elements. A component may have any number of filters, each
one describing a different capability.
For example, if the manifest contains the following:
<intent-filter . . . >
<action android:name="android.intent.action.DEFAULT" />
<category android:name="android.intent.category.MAIN" />
. . .
</intent-filter>
In the Intent output plug-in configuration, the Intent action would be:
android.intent.category.DEFAULT
