Я использую фрагменты, и когда я меняю ориентацию, происходит сбой приложения. Вот журнал кошка:

      loginTestPassword=    (EditText)view.findViewById(R.id.editTextPasswordToLogin);
       Button btnLogin = (Button) view.findViewById(R.id.buttonSignIn); 

        btnLogin.setOnClickListener(new View.OnClickListener() {

              // fetch the Password form database for respective user name
                    String storedPassword=loginDataBaseAdapter.getSinlgeEntry(userName);

                    {
                        Toast.makeText(getActivity(), "Congrats: Login Successfull", Toast.LENGTH_LONG).show();

                        // Intent intent = new Intent(getActivity(), Admin_Page.class);

                        Intent open=new Intent("com.example.bajraregistertesteclipse.ADMIN_PAGE");

                        getActivity().startActivity(open);
                        // startActivity(open);

                    }
                    else
                    {
                        Toast.makeText(getActivity(), "User Name or Password does not match", Toast.LENGTH_LONG).show();
                    }

            }

        });

   return view;
}


@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    loginDataBaseAdapter=new LoginDataBaseAdapter(getActivity());
     loginDataBaseAdapter=loginDataBaseAdapter.open();
}

Мой Mainfest.xml:

Теперь моя проблема - сбой приложения при изменении ориентации, а при нажатии на кнопку должно быть инициировано новое действие Admin_Page, но сбой приложения.

Заранее спасибо!!!
