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

See below how is the construction of 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, "

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

                + ");");


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

        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("

                + "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 name refactore on my project this morning. After that it stopped working.

The app is running normally and without any logcath however the functions that require sqlite do not work.

I’ve checked all the places that had the old name of the application and fixed them all, yet still nothing working.

Does anyone have any idea what it might be?

android sqlite

  • I’m not sure, I could be wrong, but the onCreate is only called when the schema is first created, no more. Would that be the problem? Or would it be any access to these tables are not working, while recovering the readableDatabase or writetableDatabase? Another thing I realized is that in onUpgrade, you end up dropping the tables, but don’t recreate them again, that’s right?

  • Try deleting the data from the app or uninstall it and try again.

This occurred because you changed the name of the bank and did not change the version, try to change this part:

static final int DB_VERSION = 1;

To

static final int DB_VERSION = 2;

Be careful because the way your code is, it will erase all data from the old version. Make a backup instead.
