Question

I’m new to programming. I’m making an Android app and I am at a new hurtle. I am using the SQLiteOpenHelper class to manage my database. Its been great, I am able to create tables, add entries and all that good stuff.

The problem I have is that for one of my tables I want to have an initial 7 entries that keep the same ID and can be replaced by the user. My plan is to use a SQLiteDatabase.replace() method in order to replace these entries. Since I want the entries to be set by me and then edited by the user, that means I want to add entries using the SQLiteOpenHelper class so that these entries are set only when the user installs the app and creates the database. I do not want to make a pre-populated database that I must include in the install package.

My Java skills are god awful so my main question is how do I add entries from inside my SQLiteOpenHelper class? I already know how to add entries in my other classes using the following method that I made:

public long createCategoriesSQLEntry(String name) {
    ContentValues cv = new ContentValues();
    cv.put(COLUMN_CATEGORIES, name);
    return myDatabase.insert(StringCategory_Table, null, cv);
}

Override the onCreate() in the database helper. Like this.

@Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
        try{
            if(db.isOpen()){
                //create tables here
                db.execSQL("create table");
                db.execSQL("insert row");
                db.execSQL("insert row");
            }
        }
