I am new in retrofit. I completed all setup. I add this gradle in build.gradle file
compile 'com.squareup.retrofit2:retrofit:2.0.2'
    compile 'com.squareup.retrofit2:converter-gson:2.0.2'
My Interface is like this:
public interface ILoginInterface {
    String BASE_URL= "MY_BASE_URL/";
    @POST("MY/API")
    Call<LoginResponseEntity> startLogin(@Body JSONObject jsonObject);
    class Factory{
        private static ILoginInterface instance;
        public static ILoginInterface getInstance(){
            if(instance==null){
                Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl(BASE_URL)
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();
                instance = retrofit.create(ILoginInterface.class);
            }
            return instance;
        }
    }
}
My Calling procedure is like this:
ILoginInterface.Factory.getInstance().startLogin(jsonObject).enqueue(new Callback<LoginResponseEntity>() {
                @Override
                public void onResponse(Call<LoginResponseEntity> call, retrofit2.Response<LoginResponseEntity> response) {
                    Log.d("MS",response.body().fullName);
                }
                @Override
                public void onFailure(Call<LoginResponseEntity> call, Throwable t) {
                    Log.d("MS",t.getMessage());
                }
            });
Here jsonObject is like this:
{"user_name":"sajedul Karim", "password":"123456"}
Here it seems everything is ok but i didn't getting proper response. I found a solution. it is here . Does anybody have proper solution like Volley JsonObjectRequest
