I got the ArtModel object sent from the previous activity and displayed it basically

FullScreenImage.java

package com.example.sep.loveartlearnart;


import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ImageView;
import android.widget.Toast;

import org.parceler.Parcels;

        this.fullimageview = (ImageView) findViewById(R.id.full_image_view);

        // Initialize the selected art as null
        ArtModel model = null;

        // Here I tried to get the selected ArtModel object by unwrapping the parcelable sent from the
        //  previous activity

            model = Parcels.unwrap(intent.getParcelableExtra("selected_art"));
        }catch (Exception e){
            e.printStackTrace();
        }

        if (model != null){
            displayArt(model);
        }
        else {
