The AndroidManifest.xml File
—  The manifest presents essential information about
the application to the Android system, information
the system must have before it can run any of the
application's code.
—  It names the Java package for the application. The
package name serves as a unique identifier for the
application.
—  It describes the components of the application — the
activities, services, broadcast receivers, and content
providers that the application is composed of. These
declarations let the Android system know what the
components are and under what conditions they can
be launched.

The Android SDK Emulator
The Android SDK
includes a mobile
