Working with External Libraries

You can register any shared libraries your application links to within

the Android manifest file. By default, every application is linked to

the standard Android packages (such as android.app) and is aware

of its own package.However, if your application links to additional

packages, they must be registered within the <application> tag of

the Android manifest file using the <uses-library> tag. For example

more information about the <uses-library> tag of the Android

manifest file, see the Android SDK reference.

Each Activity within the application must be defined within the

Android manifest file with an <activity> tag. For example, the

This Activity must be defined as a class within the

com.androidbook.multimedia package. That is, the package

specified in the <manifest> element of the Android manifest file.
