I need to parse JSON array from Retrofit. I need to get the following key: { "rc":0, "message":"success", "he":[ { "name":"\u05de\u05e4\u05e7\u05d7", "type":0 } ] } I can easily get the message but I am not able to get "he" array from response. Here is my data model class public class GetRoleData implements Serializable { @SerializedName("he") private ArrayList<Roles> he; @SerializedName("message") private String message; public GetRoleData() { this.he = new ArrayList<>(); this.message = ""; } public ArrayList<Roles> getUserRoles() { return he; } public String getMessage() { return message; } public class Roles { public Roles() { name = ""; type = -1; } @SerializedName("name") private String name; @SerializedName("type") private int type; public int getType() { return type; } public String getName() { return name; } } } This is how I am sending request to the server: @POST("index.php/") Call<GetRoleData> getUserRoles(@Body SetParams body); here is how i am sending request and handling response APIService apiService = retrofit.create(APIService.class); Call<GetRoleData > apiCall = apiService.getUserRoles(params); apiCall.enqueue(new Callback<GetRoleData >() { @Override public void onResponse(retrofit.Response<GetRoleData > mUserProfileData, Retrofit retrofit) { Log.e("locale info", "mUserProfileData = " + mUserProfileData.body().toString()); if (pDialog != null) { pDialog.dismiss(); } if (mUserProfileData.body().getMessage().equals("success")) { Log.e("locale info", "user roles = " + mUserProfileData.body().getUserRoles().size()); } else { Toast.makeText(RegisterActivity.this, getResources().getString(R.string.get_role_error), Toast.LENGTH_SHORT).show(); } } @Override public void onFailure(Throwable t) { if (pDialog != null) { pDialog.dismiss(); } t.printStackTrace(); } }); What i want I need to get the "he" array from above response. Please help Thanks. here is response that i am getting..

Another easy way of getting data using webservices is by using JsonElement and then convert it into JsonObject and parse JsonObject. Ez-Pz.

Note : JsonObject is not same as JSONobject, JsonObject belongs to GSON's library

UPDATE FOR Retrofit 2.0-beta2:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.google.code.gson:gson:2.4'
    compile 'com.squareup.okhttp:okhttp:2.5.0'
    // compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.retrofit:retrofit:2.0.0-beta2'
    compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2'
}

Interface:

@GET("/api/values")
Call<GetRoleData> getUserRoles();

MainActivity's onCreate:

        // Retrofit 2.0-beta2
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(API_URL_BASE)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        WebAPIService service = retrofit.create(WebAPIService.class);

        // Asynchronous Call in Retrofit 2.0-beta2
        Call<GetRoleData> call = service.getUserRoles();
        call.enqueue(new Callback<GetRoleData>() {
            @Override
            public void onResponse(Response<GetRoleData> response, Retrofit retrofit) {
                ArrayList<GetRoleData.Roles> arrayList = response.body().getUserRoles();
                if (arrayList != null) {
                    Log.i(LOG_TAG, arrayList.get(0).getName());
                }
            }

            @Override
            public void onFailure(Throwable t) {
                Log.e(LOG_TAG, t.toString());
            }
        });

Retrofit 1.9

I use your GetRoleData class

The interface:

public interface WebAPIService {        

    @GET("/api/values")
    void getUserRoles(Callback<GetRoleData> callback);                       
}

MainActivity:

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

        // creating a RestAdapter using the custom client
        RestAdapter restAdapter = new RestAdapter.Builder()
                .setEndpoint(API_URL_BASE)
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .setClient(new OkClient(mOkHttpClient))
                .build();

        WebAPIService webAPIService = restAdapter.create(WebAPIService.class);

        Callback<GetRoleData> callback = new Callback<GetRoleData>() {
            @Override
            public void success(GetRoleData getRoleData, Response response) {
                String bodyString = new String(((TypedByteArray) response.getBody()).getBytes());
                Log.i(LOG_TAG, bodyString);
            }

            @Override
            public void failure(RetrofitError error) {
                String errorString = error.toString();
                Log.e(LOG_TAG, errorString);
            }
        };

        webAPIService.getUserRoles(callback);
    }

Mocky for tests -> http://www.mocky.io/v2/567275072500008d0e995b2c I'm using Retrofit 2 (beta-2). This works for me, nothing special about it:

Call definition:

@GET("/v2/567275072500008d0e995b2c")
Call<Base> getMock();

Models:

public class Base {
    public int rc;
    public String message;
    public List<Role> he;
}

public class Role {
    public String name;
    public int type;
}

Retrofit:

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

Call execute:

webservice.getMock().enqueue(new Callback<Base>() {
    @Override
    public void onResponse(Response<Base> response, Retrofit retrofit) {

    }

    @Override
    public void onFailure(Throwable t) {

    }
});

You have written all your getters except he correctly. In order for Retrofit to parse your JSON file, you should write your getter for he variable as follows.

public ArrayList<Roles> getHe() {
    return he;
}

Also, try removing new ArrayList from the constructor.

public GetRoleData() {
    // this.he = new ArrayList<>(); // <-- Remove here
    this.message = "";
}

// Use the following Pojo Classes

public class GetRoleData {

@SerializedName("rc")
@Expose
private Integer rc;
@SerializedName("message")
@Expose
private String message;
@SerializedName("he")
@Expose
private List<He> he = new ArrayList<He>();

/**
*
* @return
* The rc
*/
public Integer getRc() {
return rc;
}

/**
*
* @param rc
* The rc
*/
public void setRc(Integer rc) {
this.rc = rc;
}

/**
*
* @return
* The message
*/
public String getMessage() {
return message;
}

/**
*
* @param message
* The message
*/
public void setMessage(String message) {
this.message = message;
}

/**
*
* @return

*/
public List<He> getHe() {
return he;
}

/**
*
* @param he
* The he
*/
public void setHe(List<He> he) {
this.he = he;
}

}
-----------------------------------com.example.He.java-----------------------------------

package com.example;

import javax.annotation.Generated;

public class He {

}

/**

public void setName(String name) {
this.name = name;

/**

public Integer getType() {
return type;
}

/**

public void setType(Integer type) {
