Why use SQLiteOpenHelper over SQLiteDatabase?

Question

In my activity I have for example

SQLiteDatabase db = openOrCreateDatabase(Preferences.DB_NAME, Context.MODE_PRIVATE, null);
db.execSQL(\"CREATE TABLE IF NOT         


        

Answer 1

Above of other answers, one very important feature in SQLiteOpenHelper class, it has 2 synchronized methods, getWritableDatabase() and getReadableDatabase().

That means your database operations are thread safe.

Code snippet from SQLiteOpenHelper class

public SQLiteDatabase getReadableDatabase() {
    synchronized (this) {
        return getDatabaseLocked(false);
    }
}

and

public SQLiteDatabase getWritableDatabase() {
    synchronized (this) {
        return getDatabaseLocked(true);
    }
}
