




Child tag of <activity>
First, what’s an intent? In OO-speak an intent is a message sent
from one program to another (message dispatcher) to tell the
system what to do next.
Typically an intent consists of two parts; an action and the data
that that action is supposed to use to do it.
When you select an icon on the main page the intent is to run the
app associated with that icon.
The tag is used to construct an android.content.IntentFilter object
to handle a particular android.content.Intent

14. Launcher



When you create a new application using the
Android SDK tools.
The stub activity that's created for you
automatically includes an intent filter that
declares the activity responds to the "main"
action.
It should be placed in the "launcher" category.
