Data Get in Json using Retrofit

Expected BEGIN_ARRAY but was STRING at line 3 column 26 path $[0].data

public class MainActivity extends AppCompatActivity {

    Api_Interface api_interface;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        api_interface=ApiClient.getClient().create(Api_Interface.class);

        Call<List<CountryClas>> call=api_interface.getcountry("GetCountry","727","cl1oEntQ32PxZsS3VJnC+H+CY5oLfFLRU5j1H4bg+1g=");




      call.enqueue(new Callback<List<CountryClas>>() {
            @Override
            public void onResponse(Call<List<CountryClas>> call, Response<List<CountryClas>> response) {
                Log.e("Res",">>>>>>"+response.body());
                }

            @Override
            public void onFailure(Call<List<CountryClas>> call, Throwable t) {
                Log.e("Error",">>>>>>"+t.getMessage());
            }
        });
    }

}

InterFace

public interface Api_Interface {

@GET("json.php")
Call<List<CountryClas>> getcountry(@Query("action") String action, @Query("umID") String umID
        , @Query("OauthToken") String OauthToken);

}

ApiClient

public class ApiClient {
    private static final String BaseUrl="http://23.227.133.210/consultapro/";

    private static Retrofit retrofit=null;

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

Model Class

public class CountryClas {

    @SerializedName("status")
    @Expose
    private Boolean status;
    @SerializedName("data")
    @Expose
    private List<Datum> data = null;
    @SerializedName("message")
    @Expose
    private String message;

    public Boolean getStatus() {
        return status;
    }

    public void setStatus(Boolean status) {
        this.status = status;
    }

    public List<Datum> getData() {
        return data;
    }

    public void setData(List<Datum> data) {
        this.data = data;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

}

Second Model Class

public class Datum {

    @SerializedName("Country_Id")
    @Expose
    private String countryId;
    @SerializedName("Country_Name")
    @Expose
    private String countryName;
    @SerializedName("Country_Code")
    @Expose
    private String countryCode;

    public String getCountryId() {
        return countryId;
    }

    public void setCountryId(String countryId) {
        this.countryId = countryId;
    }

    public String getCountryName() {
        return countryName;
    }

    public void setCountryName(String countryName) {
        this.countryName = countryName;
    }

    public String getCountryCode() {
        return countryCode;
    }

    public void setCountryCode(String countryCode) {
        this.countryCode = countryCode;
    }

}

//Json Response

[ { "status": true, "data": [ { "Country_Id": "101", "Country_Name": "India", "Country_Code": "91" }, { "Country_Id": "231", "Country_Name": "United States", "Country_Code": "1" }, { "Country_Id": "230", "Country_Name": "United Kingdom", "Country_Code": "44" } ], "message": "Country list found." } ]

//There are some issue to define in InterFace here is code

public interface Api_Interface {

    Call<List<CountryClas>> getcountry(@Field("action") String action, @Field("umID") String umID

you can convert your response body to Java Objects/List using Gson. See code sample below

req.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, retrofit2.Response<ResponseBody> response) {

            BufferedReader reader = null;
            StringBuilder sb = new StringBuilder();
            reader = new BufferedReader(new InputStreamReader(response.body().byteStream()));
            String line;
            try {
                while ((line = reader.readLine()) != null) {
                    sb.append(line);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            String result = sb.toString();

            ApiResponse apiResponse = new Gson().fromJson(result, ApiResponse.class);

I try to connect your api without authentication

http://23.227.133.210/consultapro/json.php?action=getCountry,

then I get the response like this

[{"status":false,"data":"-->getCountry-->3JfalKdsUf15fsfGIwjcXg== -->","message":"User is not authenticated."}]

in data, it return String instead of ARRAY

So I think because you request with an invalid authentication It will make your model is incorrect -> JsonParseException

Sorry for my bad english

That means your Json data model is wrong. Just use some online json to Java model converter to generate model if you dont know what is wrong.

try this converter

This model should actually work if you posted right Json string

class Country {
@SerializedName("status")
private Boolean status;

@SerializedName("data")
private List<Data> data = null;

@SerializedName("message")
private String message;

public class Data {
    @SerializedName("Country_Id")
    private String countryId;

    @SerializedName("Country_Name")
    private String countryName;

    @SerializedName("Country_Code")
    private String countryCode;
}}

'Expected BEGIN_ARRAY but was STRING' means your member variable which you have define their datatype is not matching, it's expecting as String[] might be, and you may have used Sting , please recheck.
