</manifest>

Things to note:

• The package name from the source file is represented here. This follows

a similar pattern to a Java source file and imports. The <manifest> tag

is in essence "importing" classes from this package. All non-fully qualified

classes in this file are found in the package identified in the package

attribute.

• The <application> tag has an attribute that references a resource

from the application's resources. Note the @ symbol preceding the

drawable identifier. This is a hint for the file to look in the drawable folder

of the application's resources for a resource called "icon."

• The <activity> tag contains the following attributes and values of note:

• class represents the Java class implementing this activity

• android:label is the name of the application. Note that it is coming

from one of the string resources. The string.xml file contains localized

strings for the application.

• <intent-filter> represents the IntentFilter available in the

sample application. This is the most common IntentFilter seen in

Android applications. This filter essentially says that it implements the

"main" action (or entry point) and is located in the launcher of the OS.

In English, this means it can be started as an application from the

primary list of applications on an Android device.

The next section describes starting the application on the Android Emulator from

within Eclipse.

Running the application

Now that the application has compiled successfully, it's time to run the sample

application. Select Open Run Dialog or shortcut on the toolbar within Eclipse. This

opens a dialog where startup configurations are created. Highlight the Android

Application option and click the icon for New.

Figure 6 show the values used for the tutorial sample.
