Composite

Composite is an annotation processor that allows defining conformance to an interface/abstract class in child projects (jar/aar) and automatic compositing of them in an app project.

Defined in messages gradle module:

@LibraryModule(NavigationRegistrable.class)
public final class MessagesNavigationRegistrable implements NavigationRegistrable {
    @Override public String menuType() {
        return "Messages";
    }

    @Override public void performMenuAction() {
        // TODO
    }
}

Defined in app gradle module:

// Triggers the annotation processor to generate the composite of all NavigationRegistrable library modules.
@AppModule(NavigationRegistrable.class)
final class AppNavigationRegistrable {
}

This will generate a class for you to use in the app gradle module called GeneratedNavigationRegistrableModule which will have a method called modules returning a Set<NavigationRegistrable> which will allow you to handle navigation in a generic way where the navigation modules included at build time are automically handled at runtime.
