Я пытаюсь создать приложение, которое будет получать некоторую информацию с сервера, используя залп. Вы должны ввести свои данные, а затем нажать кнопку «Войти» внизу, но по какой-то причине происходит сбой.
В первую очередь при нажатии кнопки происходит сбой, и logcat:

setSupportActionBar(toolbar);
TextView textView = (TextView)findViewById(R.id.currentFragDisplay);
textView.setText("My Profile");
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.fragmentContainer, new Personal_Profile_Fragment());
fragmentTransaction.commit();
}
