2.Logic：

    //Fragment：

        @Arg
        String title;
  
        @Override
        public void onCreate(Bundle savedInstanceState){
            super.onCreate(savedInstanceState);
            FragmentArgs.inject(this); // read @Arg fields
        }
  
        @Override
        public View onCreateView(LayoutInflater inflater, 
            ViewGroup container, Bundle savedInstanceState) {    
                Toast.makeText(getActivity(), "Hello " + title, 
                    Toast.LENGTH_SHORT).show();        
                return null;
          }        
    }
  
    //Activity:
    public class MyActivity extends Activity {
        public void onCreate(Bundle savedInstanceState){
            super.onCreate(savedInstanceState);    
            int id = 123;
            String title = "test";    
            // Using the generated Builder
            Fragment fragment = 
                new MyFragmentBuilder(id, title)
                .build();    
  
            // Fragment Transaction
            getFragmentManager()
                .beginTransaction()
                .replace(R.id.container, fragment)
                .commit();        
        }    
    }

• android-flux-todo-app --- (From lgvalle) : Example of how to implement an Android TODO App using Facebook Flux Architecture. [在android上探索Flux架构].

  

  There are two key features to understand Flux:

  • The data flow is always unidirectional.

    An [unidirectional data flow][unidirectional] is the core of the Flux architecture and is what makes it so easy to learn. It also provides great advantages when testing the application as discussed below.

  • The application is divided into three main parts:

    • View: Application interface. It create actions in response to user interactions.
    • Dispatcher: Central hub through which pass all actions and whose responsibility is to make them arrive to every Store.
    • Store: Maintain the state for a particular application domain. They respond to actions according to current state, execute business logic and emit a change event when they are done. This event is used by the view to update its interface.

    This three parts communicate through Actions: Simple plain objects, identified by a type, containing the data related to that action.

• flux-architecture --- (From Author lgvalle blog http://lgvalle.xyz/) --- [Source in Github]

  Finding a good architecture for Android applications is not easy. Google seems to not care much about it, so there is no official recommendation on patterns beyond Activities lifecycle management.

  But defining an architecture for your application is important. Like it or not, every application is going to have an architecture. So you'd better be the one defining it than let it just emerge. [Translation：探索Facebook的Web-Flux 架构在android上的尝试].
