An Android movies app using the MPV architecture

Popular Movies

This a movies application for the Android Developer Nanodegree Course. This app also demonstrates the use of multiple libraries with a clean architecture for fetching the data from The Movie Database API.

Setting it up with your own API KEY

In your root folder create a gradle.properties file and inside add the following line:

API_KEY = "{with you API key here}"

And you're good to go.

###Libraries

• OkHttp As a Http client.
• ButterKnife For view binding.
• Stetho For intercepting the data requested and view it with Chrome.
• Support Palette For retrieving the predominant colors in a picture.
• Glide To perform image request and loading it to the views.
• Gson For parsing the network's JSON response.

###Architecture This app uses the Model View Presenter architecture as explained in this article written by Saul Molinero at his awesome blog. With a few modifications.

Instead of dividing the entire project into the three main layers of the architecture I opted to divide it in features:

Rather of using Otto for the layers communications right now is still using callbacks interfaces and instead of using multiples classes for extending the base view, presenter and use cases are done by creating a contract interface for the feature in which each one is extending the base interface. I consider is easier to read this way.

public interface MovieDetailsContract {

    interface Presenter extends com.nunez.popularmovies.mvp.presenters.Presenter {
        void attachView(View detailsView);
        void setTrailerLink();
        void showViews();
        void showPoster(String url);
        void showTitle (String title);
        void showDescription(String description);
        void showTrailers();
        void showReviews();
    }

    interface View extends MVPView{
        void setTrailerLink(String url);
        void showPoster(String url);
        void showTitle (String title);
        void showDescription(String description);
        void showTrailers(ArrayList<Video> trailers);
        void showReviews(ArrayList<Review> reviews);
    }

     interface MovieDetailsController extends UseCase{
         void requestMovieDetails();
         void sendMovieDetailsToPresenter(Movie movie);
    }
}
