Retrofit JSON Error parsing error

Question

Retrofit gives me this error when I try to parse the following JSON response

Raw

[{"DeviceName":"Samsung Galaxy A5","Brand":"Samsung"...},{"DeviceName":"Samsung Galaxy A5 Duos"... ...]

Pretty

Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

@FormUrlEncoded
@PATCH("/v1/getphone/")
Call<List<Phone>> getPhoneInfo(@Field("device") String device);

Java Class

public class Phone {
@SerializedName("DeviceName")
@Expose
public String DeviceName;
@SerializedName("Brand")
@Expose
public String Brand;
@SerializedName("technology")
@Expose
public String technology;
....

Any help? Thanks

Answer 1

Put your Phone class inside another class as a list:

public class Root {

private List<Phone> phone;

//getters and setters here
}

and change this line:

Call<List<Phone>> getPhoneInfo(@Field("device") String device);

to

Call<Root> getPhoneInfo(@Field("device") String device);

In retrofit you need an array name to create a class with.your json is valid but the response doesn't have any array name so it won't be able to parse in that way.you have to parse it manually by getting json string from your response in retrofit like this

  ApiServiceClient.getApiService().yourFunctionName().enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Response<ResponseBody> response, Retrofit retrofit) {
                try {
                    String jsonString=response.body().string();
                    Log.e(TAG, "onResponse: "+response.body().string());
                     //Parse your json here
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

            @Override
            public void onFailure(Throwable t) {

            }
        });
