this is how i am making a retrofit call

public interface ApiInterface {

    @GET("plzw3")
    Call<ResponseMode> getAllJobs();


    @GET("top-headlines?sources=techcrunch&apiKey=801d8c3455fe475bbab9f7e4c6944aa3")
    Call<ResponseMode> getLatestNews();


}




public class ResponseMode {

    @SerializedName("results")
    private List<AllJobsModel> allJobsModelList;

    public List<AllJobsModel> getAllJobsModelList() {
        return allJobsModelList;
    }

    public void setAllJobsModelList(List<AllJobsModel> allJobsModelList) {
        this.allJobsModelList = allJobsModelList;
    }
}


public class ApiClient {

//    public static final String BASE_URL = "https://newsapi.org/v2/";
    public static final String BASE_URL = "https://api.myjson.com/bins/";
    private static Retrofit retrofit = null;


    public static Retrofit getClient() {
        if (retrofit==null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}




  private void fetchJobs() {
        ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);

        Call<ResponseMode> call = apiService.getAllJobs();

        call.enqueue(new Callback<ResponseMode>() {
            @Override
            public void onResponse(Call<ResponseMode> call, Response<ResponseMode> response) {

                // data parsing


                List<AllJobsModel> news = response.body().getAllJobsModelList();


                // inserting data into database
                allJobsModelDao.insertOrReplaceInTx(news);

                // setting up adapter
                setAdapter();
            }

            @Override
            public void onFailure(Call<ResponseMode> call, Throwable t) {

            }


        });
    }

what can i do tio fix this ?? any help is highly appriciated

Answer 1

Try changing to private List<Long> merits;

Your code would work if response is like this

 "merits":[
     {
         "merit_id":47
     },
     {
         "merit_id":51
     },
     {
         "merit_id":56
     }
 ]
