Android Error: Too many bind arguments. 1 arguments were provided but the statement needs 0 arguments

I am deleting a database on Clicking a button and my delete method is as follows

 public int deleteDatabase(String tableName) {
    SQLiteDatabase db = database.getWritableDatabase();

    String whereClause = null; // delete all rows
    String[] whereArgs = { null };
    int count = db.delete(tableName, whereClause, whereArgs);
    db.close();
    return count;

}

 if (DatabaseHelper.getInstance(getApplicationContext())
                .isTableExists(MY_TABLE)) {
            Log.d(TAG, "Table exist, delete database");
            deleteDatabase(MY_LIST_TABLE);

        }

and the error is as follows: Too many bind arguments. 1 arguments were provided but the statement needs 0 arguments.
