		android.app.ApplicationContext		ViewInflate.Factory
			android.app.Application

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's <application> tag, which will cause that class to be instantiated for you when the process for your application/package is created.
