A company might do this, for example, to use the company’s branding colors. Just as in a Java subclass, a style can override parent theme attributes with values customized for specific apps. This style also specifies a parent theme, which is similar to a superclass in Java-the new style inherits its parent theme’s attributes and their default values. The style.xml resource file contains a style with the name 'AppTheme' that’s referenced from the app’s AndroidManifest.xml file to specify the app’s theme.
