Retrofit Android studio post the data on Server.

We will post the following data.
{
"token":"6536a951423727727c47ed18004e2f30z",
"book_req_category": 1,
"books": [{
    "name": "Flamingo",
    "Class": "12th",
    "medium": "English",
    "is_ncert": 1,
    "publisher_name": "NCERT",
    "type": 0
}]
}

Creating New Project.

Open android studio and create a new project.
File => New => New Project => Configure your new project => Select the form factor yours app will run on => Add an Activity to Mobile => Customize the Activity => Finish.

First we need to add Volley Library to our project.  
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'

Create the Api Client java class in project.
Open app => main => src = ApiClient.java

import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

/**
 * Created by Laptop on 8/9/2016.
 */
public class ApiClient {
    private static Retrofit retrofit = null;

    public static Retrofit getClient() {
        if (retrofit == null) {
            retrofit = new Retrofit.Builder().baseUrl("http://books.vevsa.com:7001/")
                    .client(new OkHttpClient())
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}

Create the Response java class in project.
Open app => main => src = Response.java

import com.google.gson.annotations.SerializedName;

/**
 * Created by Laptop on 8/9/2016.
 */
public class Response {
    @SerializedName("log")
    private String log;

    public int getFlag() {
        return flag;
    }

    public void setFlag(int flag) {
        this.flag = flag;
    }

    public String getLog() {
        return log;
    }

    public void setLog(String log) {
        this.log = log;
    }

    @SerializedName("flag")
    private int flag;
}


Create the Interface in project.
Open app => main => src = RetrofitInterface

import okhttp3.RequestBody;
import retrofit2.Call;
import retrofit2.http.Body;
import retrofit2.http.Headers;
import retrofit2.http.POST;/**
 * Created by Laptop on 8/9/2016.
 */
public interface RetrofitInterface {
    //TODO: Please check curly bracket at end point of api name :)
    @POST("req_book_auth/raise_request")
    @Headers("Accept: application/json")
    Call<Response> getAllData(@Body RequestBody params);
