The magic method createTable() to handle creation of the given fields automatically

DatabaseHelper.java

private void createTable(String tableName, Map<String, String> fields, SQLiteDatabase db) {
    Iterator iter = fields.entrySet().iterator();
    String columns = "(";
    Log.d("column", columns);
    int counter = 1;
    while (iter.hasNext()) {
        Map.Entry mEntry = (Map.Entry) iter.next();
        columns += mEntry.getKey() + " " + mEntry.getValue();
        if (counter == fields.size()) {
            columns += ")";
        } else {
            columns += " , ";
            counter++;
        }
    }
    if (counter > 1) {
        Log.d("column", columns);
        String createNewTable = "CREATE TABLE IF NOT EXISTS " + tableName + " " + columns;
        db.execSQL(createNewTable);
    }
}
