Clear sqlite database at a certain point of an application

I want to clear my SQLite db every time I hit a particular spot in my application.

I intended on just making a method that I could call called resetTables(), but this seems to be more challenging than I expected because I don't really know where to place it. Here is a snippet.

@Override
        public void onCreate(SQLiteDatabase db) {

            db.execSQL(DATABASE_CREATE);

        }
        public void reset(SQLiteDatabase db) {

            db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);

        }

I'm getting a yellow line under reset and I can't call this method in my code. Any ideas?

Note this question is similar, but couldn't get it to help me.

This worked:

public void resetTables(){
        mDb.delete(TABLE_NAME, null, null);
    }

first create one method where you create your database and table.

 /**
     * Re crate database
     * Delete all tables and create them again
     * */
    public void resetTables(){
        SQLiteDatabase db = this.getWritableDatabase();
        // Delete All Rows
        db.delete(TABLE_NAME, null, null);
        db.close();
    }

and call above method using on your button click event.

i have done it by this way...

@Override
public void onOpen(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    super.onOpen(db);

     db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
}

and yes it definitely worked for me..:)
