Я пытаюсь создать страницу входа/регистрации в своем Android-приложении с помощью SQLite. Прямо сейчас мое приложение разбивается на странице регистрации (где вы создаете новую учетную запись, используя адрес электронной почты/пароль. Ниже приведены коды для моей страницы регистрации и страницы DatabaseHelper. Обратите внимание, что в моем приложении указано, что ошибка находится в helper.insertContact . (с) линия SignUp, что приводит нас к ошибке в методе insertContact в DatabaseHelperРегистрация Страница Использование приложения SQLite Crash для Android

Это код SignUp

"email text not null, pass text not null);";
public DatabaseHelper (Context context){
super (context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db){
db.execSQL(TABLE_CREATE);
this.db = db;
}
public void insertContact(Contact c){
db = this.getWritableDatabase();

int count = cursor.getCount();
values.put(COLUMN_ID, count);

db.close();
}
public String searchPass(String email){

String query = "select email, password from " + TABLE_NAME;
Cursor cursor = db.rawQuery(query, null);
String a, b;
b = "not found";
if (cursor.moveToFirst()){
do{
a = cursor.getString(0);
b = cursor.getString(1);
if(a.equals(email)){
b = cursor.getString(1);
break;
}
}

}
return b;
