[FIXED] Error: onFailure:com.google.gson.JsonSyntaxException: java.lang.NumberFormatException: Expected an int but was 57213780054

Issue

Cannot get the Response from the Retrofit showing the JsonSyntaxException. I am getting the perfect response in Logcat by HTTPLoggingInterceptor but unable to get the resonse on onSuccess() method in call.enque().

Here is my api.

APIClient.java

 public class APIClient {

private static Retrofit retrofit = null;
private static final String BASE_URL = "https://ps-test.myshopify.com/admin/";

public static Retrofit getClient() {

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

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

    return retrofit;
  }
}

ApiInterface.java

public interface ApiInterface {

    @GET("collection_listings.json")
    Call<Example> getCollectionList(@Header("Authorization") String accessToken);
}

Implementation in Activity:

private void fillListCategories() {

    apiInterface = APIClient.getClient().create(ApiInterface.class);

    Call<Example> call = apiInterface.getCollectionList("Basic OWUzNmY1NWVlNGY1NTk0YWE4OTFkZjg4MTAyYzBhMjg6MWQ3MmM0YmIwMzBiZmNlOTM5OWRlYmM4NjM3ZWFlYjM=");

    call.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(Call<Example> call, Response<Example> response) {
            if (response.isSuccessful()) {
                Log.d("Collection List", "onResponse:" + response.body());
            }
        }

        @Override
        public void onFailure(Call<Example> call, Throwable t) {
            Log.d("Issue", "onFailure:" + t.fillInStackTrace());
        }
    });
}

Thanks in advance.

Solution

Try to get collection_id as long var or string in your Example class. because you are getting collection_id as a int but it's out of int range.

Hope this will help you.
