Retrieving Integer value from the Database SQLite

This is the main activity. I was trying to retrieve the value of EDIBLE PORTION which is INTEGER. But the problem is when I run it, It crashed, i don't know why need some help here. package com.apk.foodanalyzer.healthandnutrifactsanalyzer;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;

import com.apk.foodanalyzer.healthandnutrifactsanalyzer.goactivity.DatabaseHelper;
import com.apk.foodanalyzer.healthandnutrifactsanalyzer.goactivity.DoBackEnd;
import com.apk.foodanalyzer.healthandnutrifactsanalyzer.goactivity.GoItem;
import com.apk.foodanalyzer.healthandnutrifactsanalyzer.goactivity.GoItemContent;

import java.sql.RowId;

/**

public class GoValueActivityContent extends AppCompatActivity {

    private TextView FoodDescription, Scientificname, AlternateName,EdiblePortion;

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


        Intent intent = getIntent();
        Bundle bundle = intent.getExtras();
        int dictionaryId = bundle.getInt("RowId");
        int search = dictionaryId + 1;

            FoodDescription = (TextView)findViewById(R.id.go_conent_fooddescription);
            Scientificname = (TextView)findViewById(R.id.go_conent_scientificname);
            AlternateName = (TextView)findViewById(R.id.go_content_alternatename);
            EdiblePortion = (TextView)findViewById(R.id.goedibleportion_value);

            DoBackEnd dbBackend = new DoBackEnd(GoValueActivityContent.this);
            GoItemContent allQuizQuestions = dbBackend.getQuizById(search);

            FoodDescription.setText(allQuizQuestions.getFoodDescription());
            Scientificname.setText(allQuizQuestions.getScientificName());
            AlternateName.setText(allQuizQuestions.getAlternateName());
            EdiblePortion.setText(allQuizQuestions.getEdiblePortion());


    }
}

This is the Object

public class GoItemContent {
    private String FoodDescription;
    private String ScientificName;
    private String AlternateName;
    private Integer EdiblePortion;

    public GoItemContent(String foodDescription, String scientificName, String alternateName, Integer ediblePortion) {
        FoodDescription = foodDescription;
        ScientificName = scientificName;
        AlternateName = alternateName;
        EdiblePortion = ediblePortion;
    }

    public String getFoodDescription() {
        return FoodDescription;
    }

    public void setFoodDescription(String foodDescription) {
        FoodDescription = foodDescription;
    }

    public String getScientificName() {
        return ScientificName;
    }

    public void setScientificName(String scientificName) {
        ScientificName = scientificName;
    }

    public String getAlternateName() {
        return AlternateName;
    }

    public void setAlternateName(String alternateName) {
        AlternateName = alternateName;
    }

    public Integer getEdiblePortion() {
        return EdiblePortion;
    }

    public void setEdiblePortion(Integer ediblePortion) {
        EdiblePortion = ediblePortion;
    }
}

and my METHOD

public GoItemContent getQuizById(int quizId){

        GoItemContent quizObject = null;
        String query = "SELECT FoodDescription, ScientificName, AlternateName, EdiblePortion FROM GoTable WHERE RowId = " + quizId;
        Cursor cursor = this.getDbConnection().rawQuery(query, null);
        if(cursor.moveToFirst()){
            do{

                String fooddescription = cursor.getString(cursor.getColumnIndexOrThrow("FoodDescription"));
                String scientificname = cursor.getString(cursor.getColumnIndexOrThrow("ScientificName"));
                String alternatename = cursor.getString(cursor.getColumnIndexOrThrow("AlternateName"));
                int edibleportion = cursor.getInt(cursor.getColumnIndexOrThrow("EdiblePortion"));


                quizObject = new GoItemContent(fooddescription,scientificname,alternatename,edibleportion);
            }while(cursor.moveToNext());
        }
        cursor.close();
        return quizObject;
    }

Thank you in advance. :)
