Android SQLiteOpenHelper: Why onCreate() method is not called?

Question

I am trying to make my first Android app. I noticed that the SQLiteOpenHelper.onCreate() method is not called to create tables if the database not exists. Howev

Answer 1

I had the same problem where it seemed that the onCreate was not executed. I thought so because my logs were not displayed. Turned out that there was something wrong with the blank spaces in my SQL_create String.

@Override
public void onCreate(SQLiteDatabase db) {
    try {
        Log.d(LOG_TAG, "A table is created with this SQL-String: " + SQL_CREATE + " angelegt.");
        db.execSQL(SQL_CREATE);
    }
    catch (Exception ex) {
        Log.e(LOG_TAG, "Error when creating table: " + ex.getMessage());
    }
}

This is my corrected SQL-String:

enterpublic static final String SQL_CREATE =
        "CREATE TABLE " + TABLE_VOCAB_LIST +
                "(" + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                COLUMN_GERMAN + " TEXT NOT NULL, " +
                COLUMN_SPANISH + " INTEGER NOT NULL, "+
                COLUMN_LEVEL + " INTEGER NOT NULL);)"; code here

I had forgotten one blank space and when I added it everything worked fine.
