An Agera practicing app

#AgeraBeauties

A sample App based on Gank.io's Api, using Agera as the model engine.

#Why

Recently,there are so many Apps choosing RxJava+retrofit+MVP to be the framework of itself,while I thought Agera may be the better one in Android platform instead of RxJava because the latter is so heavy and Agera can do all the things RxJava does.

So I made this App to show how to use Agera to replace RxJava in the model layer of an Android App.

#How Agera works

Agera+retrofit:

BeautyApi api = BeautyService.getInstance().getNetEngine().create(BeautyApi.class);
repository = Repositories.repositoryWithInitialValue(beauty)
                .observe()
                .onUpdatesPerLoop()
                .goTo(Executors.newSingleThreadExecutor())
                .thenAttemptGetFrom(api.getUserInfo(page++))
                .orEnd(errorHandler)
                .compile();

AgeraBus:

AgeraBus.eventRepositories().post(new LoadEvent(true,lastAction,beauties.results));

@Override
public void onEventReceiveInMain() {
    Object event = AgeraBus.eventRepositories().get();
    if(event instanceof LoadEvent){
        if(!((LoadEvent) event).isSuccess){
            beauties.showNoDataView();
            return;
        }
        if(((LoadEvent) event).reqType == MainPresenter.REFRESH){
            beauties.stopRefresh();
        }else {
            beauties.stopLoadMore();
        }
        setBeautiesToAdapter((LoadEvent)event);
    }else if(event instanceof RouteEvent){
        RouteEvent routeEvent = (RouteEvent)event;
        if(RouterProtocol.GALLERY.equals(routeEvent.protocol)){
            jumpToGallery(routeEvent);
        }
    }
}

Saving a picture using Agera:

public void savePic(final String data) throws ExecutionException, InterruptedException {
    lastAction = ACTION_SAVE;

    repo = Repositories.repositoryWithInitialValue(data)
            .observe()
            .onUpdatesPerLoop()
            .goLazy()
            .attemptTransform(FileUtils.savePic())
            .orEnd(errorHandler)
            .thenGetFrom(successHandler)
            .compile();
}

public static Function<String,Result<Boolean>> savePic(){

    return Functions.functionFrom(String.class)
            .apply(FunctionProvider.fileStreamFunction)
            .thenApply(FunctionProvider.savePicFunction);
}

So you can see everything related with data in this App can be handled with the help of Agera.
