JavaDocs

Jus is a flexible and easy HTTP/REST client library for Java and Android.

• it is like Volley but much easier
• it is like Retrofit but infinitely more flexible

Jus is inspired by the flexibility, modularity and transparency of Google's Volley Library and the extreme simplicity of declarative API mapping of Retrofit.

Like Volley the main thing where Requests are executed is the RequestQueue.

RequestQueue queue = Jus.newRequestQueue();

and then Requests can be added to the Queue:

queue.add(new Request<String>(
                        Request.Method.GET,
                        HttpUrl.parse(BeerService.fullUrl),
                        new Converters.StringResponseConverter())
                        .addResponseListener((r) -> out.println("RESPONSE: " + r))
                        .addErrorListener((e) -> out.println("ERROR: " + e))
        );

Anther option similarly to Retrofit is to map Java Interface to an API.

public interface BeerService {
    @GET("locquery/{user}/{q}")
    Request<String> getBeer(
            @Path("user") String user,
            @Path("q") String q);
}

Then create the Service Instance:

RetroProxy retroJus = new RetroProxy.Builder()
            .baseUrl(BeerService.baseUrl)
            .requestQueue(queue)
            .addConverterFactory(new BasicConverterFactory())
            .build();

    BeerService beerService = retroJus.create(BeerService.class);

And execute a request:

beerService.getBeer(BeerService.userString, "777")
                .addResponseListener((r) -> out.println("RESPONSE: " + r))
                .addErrorListener((e) -> out.println("ERROR: " + e.networkResponse));
