Question

My request fails doing a call

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(MyAPI.BASE_URL)
        .addConverterFactory(JacksonConverterFactory.create())
        .build();

// prepare call in Retrofit 2.0
MyAPI myAPI = retrofit.create(MyAPI.class);

**// Debug fails here on line below**
Call<List<Place>> call = myAPI.loadPlaces(3, "restaurant");

My interface

//  Base search url, trailing slash needed
String BASE_URL = "https://test.domain.com/";

@GET("place/search")
Call<List<Place>> loadPlaces(
        @Query("count") int amountOfResults,
        @Query("filter_category") String category);

Unfortunately this question did not helped, while most search results are using Gson and RxJava

Is there a way to get results without using a call?

Answer 1

You can use rxJava library, for that you have to use specific call adapter factory during Retrofit instance creation: .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) . Advantage of this method is that you can easily handle request in background and be notified about errors.

Observable<List<Place>> pendingResult = myApi.getPlaces();
pendingResult.subscribeOn(Schedulers.io)
.map(places -> {
    // pre- process places somehow
})
.subscribe(places -> {
// process result
}, error -> {
// handle error
}}
