java — данные не передаются следующему действию, когда php и android используются для входа и регистрации

В моем Основная деятельность я вставляю значения в базу данных, используя вставки-DB (1) .php файл .. В файле php я создаю один vault_no используя данные, которые были отправлены через код Android, и я вставляю это в базу данных.
Здесь для цели входа я использую vault_no как username.now в моем коде я передаю все, что пользователь ввел как vault_no в login.php и он проверит, vault_no есть в php или нет. Но по моему ActivityLogin.java код должен проверить valut_no и перейти к userprofile.java страница и отображать приветственное сообщение.но это не идет к другой деятельности, это просто дает { «Ошибка»: ложь} как тост сообщение.

Может кто-нибудь, пожалуйста, сообщите мне, как достичь этого .. Спасибо заранее .. !!

Может кто-нибудь, пожалуйста, посмотрите весь код и помогите мне с идеей / решением .. пожалуйста .. !!
И как только нажата кнопка «Регистрация», как получить сгенерированное vault_no вместе с полным именем из insert-db (1) .php и отобразить в другом действии в Android. Пожалуйста, помогите мне добиться этого.
