Я делаю вход в систему, в этом я использую три кнопки, в то время как нажмите кнопку «Логин», я вызываю диалог оповещений, где я использую XML-файл SignIn для макета для менеджера alertdialog, где я использую два текстовое поле для имени пользователя & Пароль & кнопку, когда нажмите на кнопку, то вызвать класс, который расширяет AsyncTask класс, там я использовать Shared Prefernce & Json для входа, но в LogCat ошибка приходит, что этоКак вызвать класс, который расширяет класс Asynctask от AlertDialogManager
