Ошибка приложения Android «К сожалению приложение остановлено» - Новое для программирования

Поскольку я новичок в программировании, мне трудно найти проблему в моем коде. Буду признателен за вашу помощь. Я знаю, что я получил NullPointerException, но я не могу найти решение:Ошибка приложения Android «К сожалению приложение остановлено» - Новое для программирования

....

Большое спасибо всем! Я изменил это. Но она по-прежнему дает мне это (* обратите внимание, я пытался добавить звук Но даже если я исключить MediaPlayer, он не работает.):

Работа с медиаплеером ??? – Piyush

Я имел в виду в своем коде. Я снова отключил звуковой файл. Но я получил звук для работы. Тем не менее, приложение все еще останавливается после выпуска моего первого класса. – user3035903

Отправьте свой код здесь ... – Piyush

Изменить этот код, как этот

add = (Button) findViewById(R.id.bAdd); 
sub = (Button) findViewById(R.id.bSub); 
display = (TextView) findViewById(R.id.tvDisplay);

thres ваша проблема, скорее всего, ваш «добавить» (попробуйте присвоить свои поля более подходящим образом, например btnAdd) по какой-то причине является нулевым

также как упоминалось в RajaReddy PolamReddy, вам нужно отдать его Button с добавлением (Button) befo re findViewById вызывает этот метод возвращает экземпляр View, а не кнопку
