Я пытаюсь найти ошибку в течение довольно долгого времени и буду признателен за любую помощь.Ошибка синтаксиса SQLiteException
Я использую логин и регистрацию для android, и я использую PHP, MySQL и SQLite. В приведенном ниже коде я пытаюсь добавить информацию в базу данных SQLite.
public class SQLiteHandler extends SQLiteOpenHelper {
private static final String TAG = SQLiteHandler.class.getSimpleName();

// Database Name

Ошибка в том, что я не могу вставить в таблицу и консоли говорит:
