Laravel и Android Студия

Question

Я успешно создал API входа с использованием laravel паспорта.

{
  "status": "success",
  "data": {
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJhdWQiOiIxIiwianRpIjoiZjdmODQ3MzZjMjFkOWQ2..."
  }
}

Я создал мобильное приложение с использованием android studio, я создаю интерфейс входа

import retrofit2.Call;
import retrofit2.http.Field;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.POST;
public interface LoginInterface {

    String LOGINURL = "http://MYIP/AnnocesPFE/public/api/";
    @FormUrlEncoded
    @POST("login")
    Call<String> getUserLogin(
            @Field("email") String email,
            @Field("password") String password
    );

}

моя проблема, когда я захожу с действительным адресом электронной почты и паролем, я не могу получить доступ к своему списку активности. Страница заблокирована на странице входа без каких-либо сообщений об ошибках.
