Parsing Json Using Retrofit gives null
0
I am trying to get data from Json using Retrofit2, but I am getting null.
I am not sure what should I put in Interface GET method?
Json Datum response:
public class DatumResponse {
@SerializedName("data")
@Expose
private List<Datum> data = null;
@SerializedName("total")
@Expose
private Integer total;
public List<Datum> getData() {
return data;
}
public void setData(List<Datum> data) {
this.data = data;
}
public Integer getTotal() {
return total;
}
public void setTotal(Integer total) {
this.total = total;
}
Retrofit class
public class JsonApi {
public static final String BASE_URL = "https://api.deezer.com";
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;
}
And my Interface:
public interface IDatum {
@GET("chart")
Call<DatumResponse> getDatum();
Thanks a lot.

are you getting response null or some data null? Your interface seems ok if you are aspecting some response in DatumResponse format calling this url api.deezer.com/charts i thinks you are missing last "/" on BASE_URL

Add complete json to JsonScheme2pojo you will get these classes
Here TrackDetailsModel is Main Model Class. using this you can get other data.
Now change
@GET("chart")
Call<DatumResponse> getDatum();
To
@GET("chart")
Call<TrackDetailsModel> getDatum();
Get data using this
ApiInterface apiInterface = ApiClient.getClient().create(ApiInterface.class);
Call<TrackDetailsModel> call = apiInterface.getDatum();
call.enqueue(new Callback<TrackDetailsModel>() {
@Override
public void onResponse(Call<TrackDetailsModel> call, Response<TrackDetailsModel> response) {
if (response.isSuccessful()) {
TrackDetailsModel model = response.body();
String trackTitle = model.getTracks().getData().getTitle();
}
}
@Override
public void onFailure (Call <TrackDetailsModel> call, Throwable t){
call.cancel();
Toast.makeText(Main.this,"Error: " + t.getLocalizedMessage(),Toast.LENGTH_SHORT).show();
}
});

@Toni0123 when you open jsonschema2pojo there will beClass nameon Right Top, Change that from Example to TrackDetailsModel . Then add your all json (that you got fromapi.deezer.com/chartto Text Section on Left.) Must Remember Source Type should be JSON and Annotation style should be GSON.
