Journey

A light weight routing helper for conductor based android applications.

Usage

Defining routes

Annotate the controllers you want registered with Journey. These will be matched based on the a dispatched URI path using Java regex matcher (so any valid regex is accepted.)

@Route("/something")
public class SomeController extends Controller {
  ...
}

You can can also use placeholders which extract data that will use the placeholder text as it's key.

@Route("/user/{user_uuid}")
public class UserController extends Controller {
  public UserController(Bundle args) {
    String userUuid = args.getString("user_uuid");
  }
}

Hooking things up

A journey requires a router and a list of routes that can be travelled. If you are using the the annotation processor then a journey provider will be compiled for you to use.

Don't forget to handle new incoming intents if you're using a single activity application.

public class MainActivity extends AppCompatActivity {

  ...

  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    router = Conductor.attachRouter(this, view, savedInstanceState);
    journey = new Journey(router, new DefaultJourneyProvider());
  }

  @Override protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    journey.routeUsing(intent);
  }
}

Intercepting transactions

You can add transaction interceptors to alter controller transactions before they are pushed to the router.

new TransactionInterceptor() {
  @Override public RouterTransaction intercept(RouterTransaction transaction) {
    return transaction.popChangeHandler(new HorizontalChangeHandler())
        .pushChangeHandler(new AutoTransitionChangeHandler());
  }
});
