Sqlite no longer runs android - app

I'm having a problem with my app, sqlite apparently is not running. All functions related to it are not working, in this application I use some functions based on external mysql these are "ok".

See below how to build my base:

package com.db;

import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DbHelper extends SQLiteOpenHelper {

    static final String TAG = "DbHelper";
    static final String DB_NAME = "storefinder_db";
    static final int DB_VERSION = 1;
    static Activity activity;

    public DbHelper(Activity act) {
        super(act.getApplicationContext(), DB_NAME, null, DB_VERSION);
        activity = act;
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL("CREATE TABLE IF NOT EXISTS categories("
                + "category_id INTEGER PRIMARY KEY,"
                + "category TEXT,"
                + "category_icon TEXT,"
                + "created_at INTEGER, "
                + "is_deleted INTEGER, "
                + "updated_at INTEGER "
                + ");");

        db.execSQL("CREATE TABLE IF NOT EXISTS stores("
                + "store_id INTEGER PRIMARY KEY,"
                + "category_id NTEGER, "
                + "created_at INTEGER, "
                + "distance TEXT, "
                + "email TEXT, "
                + "featured INTEGER, "

                + "is_deleted INTEGER, "
                + "updated_at INTEGER, "
                + "website TEXT "

                + ");");


        db.execSQL("CREATE TABLE IF NOT EXISTS reviews("
                + "review_id INTEGER PRIMARY KEY,"
                + "created_at TEXT,"

        db.execSQL("CREATE TABLE IF NOT EXISTS ratings("

                + ");");

        db.execSQL("CREATE TABLE IF NOT EXISTS photos("
                + "photo_id INTEGER PRIMARY KEY," //AUTOINCREMENT

        db.execSQL("CREATE TABLE IF NOT EXISTS favorites("
                + "favorite_id INTEGER PRIMARY KEY AUTOINCREMENT," //AUTOINCREMENT
                + "store_id INTEGER"

        db.execSQL("CREATE TABLE IF NOT EXISTS pedidos("

                + "user_id INTEGER"
                + ");");

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
        db.execSQL("DROP TABLE IF EXISTS categories");
        db.execSQL("DROP TABLE IF EXISTS favorites");
        db.execSQL("DROP TABLE IF EXISTS stores");
        db.execSQL("DROP TABLE IF EXISTS reviews");
        db.execSQL("DROP TABLE IF EXISTS ratings");
        db.execSQL("DROP TABLE IF EXISTS photos");
        db.execSQL("DROP TABLE IF EXISTS news");
        db.execSQL("DROP TABLE IF EXISTS favorites");
        db.execSQL("DROP TABLE IF EXISTS pedidos");

    }
}

It was working properly until I performed a refactor name on my project this morning. After that it stopped working.

The app is running normally and with no logcath however the functions that require sqlite do not work.

I have already checked all sites that had the old application name and fixed all of them, but still nothing works.

Does anyone have any idea what it can be?
