I was working on an android app which will run an ussd code . But application is crashing when i click on the list item. And can you tell me how to write the first value from the list in the if else statement without writing all numbers manually?
Fragment Class: it has the call functionality ...
/**
* A simple {@link Fragment} subclass.
* Activities that contain this fragment must implement the
* {@link ussd.OnFragmentInteractionListener} interface
* to handle interaction events.
* Use the {@link ussd#newInstance} factory method to
* create an instance of this fragment.

// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";

// TODO: Rename and change types of parameters
private String mParam1;
