10.10 Application Context

When an application is compiled, a class named R is created that contains references to the application resources. The application manifest file and these resources combine to create what is known as the Application Context. This context, represented by the Android Context class, may be used in the application code to gain access to the application resources at runtime. In addition, a wide range of methods may be called on an application’s context to gather information and make changes to the application’s environment at runtime.
