Onactivityresult is not working fine in nested fragment class android

I have mainfragment.java and am added the viewpager in mainfragment.java. In that viewpager have mobile_fragment.java.When i click the edit-text in mobile_fragment.java using Intent to open the phone contacts after user click the contacts, get the result using Onactivityresult, but the result was not coming in mobile_fragment.java. The Onactivityresult comes till mainfragment.java, not comes for mobile_fragment.java in viewpager. I think the problem comes for nested fragment.I done some thing in both class but i got NullpointerException error.I don't know how to solve this issue.Please help me out to solve this issue.

mainfragment.java

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (other_fragments != null){

            String phoneNo = null ;
            Uri uri = data.getData();
            Cursor cursor = getActivity().getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();

            int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            phoneNo = cursor.getString(phoneIndex);

            Intent output = new Intent();
            output.putExtra("number", ""+phoneNo);

            other_fragments.onActivityResult(requestCode, resultCode, output);

        }
    }

mobile_fragment.java 

//This fragment i have edit-text.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == PICK_CONTACT_REQUEST) {

            if (resultCode == getActivity().RESULT_OK) {


                String te=data.getStringExtra("number");
                Log.v("TAG_TA",""+te);
               // It prints the log values correctly.
                prepaid_mobilenum_edt.setText(""+data.getStringExtra("number"));//NullPointerException comes here.
            }
  }

Change your OnCreateView as

static View mContainer;
    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        mContainer=inflater.inflate(R.layout.your_layout, container, false);
        prepaid_mobilenum_edt = (EditText) mContainer.findViewById(R.id.mobile_prepaid_mobilenum_edttxt);
        return mContainer;
    }

And Update your activity result as 

    if (requestCode == PICK_CONTACT_REQUEST) {

                if (resultCode == getActivity().RESULT_OK) {

                    String te=data.getStringExtra("number");
                    Log.v("TAG_TA",""+te);
                   // It prints the log values correctly.
                    if(prepaid_mobilenum_edt==null)
                      prepaid_mobilenum_edt = (EditText) mContainer.findViewById(R.id.mobile_prepaid_mobilenum_edttxt);

   prepaid_mobilenum_edt.setText(""+data.getStringExtra("number"));


                }
