Getting NullPointerException while displaying in edittext Android

Question

I'm getting NullPointerException while consuming Soap response and printing on Activity.I saw several posts regardinng this error but nothing served my purpose. Here is my Activity code:

public class StatsActivity extends Activity {

        EditText Comm, trans, cards, shops, active, inactive;
        private String totcomm;
        private String tot_trans;
        private String Totcards;
        private String totshops;
        private String totactive;
        private String totinactive;

        SoapObject response = null;
        WSInterface wsInterface = new WebService();

        @Override


protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            Comm = (EditText) findViewById(R.id.Comm);
            trans = (EditText) findViewById(R.id.trans);
            cards = (EditText) findViewById(R.id.cards);
            shops = (EditText) findViewById(R.id.shops);
            active = (EditText) findViewById(R.id.active);
            inactive = (EditText) findViewById(R.id.inactive);

            bundle = getIntent().getExtras();


            new SoapAccessTask().execute();
        }

        public class SoapAccessTask extends AsyncTask<String,SoapObject , SoapObject> {


            @TargetApi(Build.VERSION_CODES.GINGERBREAD)
            @Override
            protected void onPreExecute() {
                // TODO Auto-generated method stub
                super.onPreExecute();
                dist = bundle.getString("district");

                builder = new AlertDialog.Builder(StatsActivity.this);
                progressDialog = new ProgressDialog(StatsActivity.this);
                progressDialog.setMessage("Processing Data...");
                progressDialog.setCancelable(false);
                progressDialog.setTitle("Please Wait");

                progressDialog.show();


            }

            @Override
            protected SoapObject doInBackground(String... params) {
                response = wsInterface.getTodayStats(dist);
                return response;
            }

            @Override
            protected void onPostExecute(SoapObject soapObject) {
                super.onPostExecute(soapObject);
                System.out.println("in post execute" + soapObject.toString());
              // got soap response here
                        progressDialog.dismiss();
                    }
                        Totcards=j.getProperty(0).toString();
                        totactive=j.getProperty(1).toString();
                        totcomm=j.getProperty(2).toString();
                        totinactive=j.getProperty(3).toString();
                        totshops=j.getProperty(4).toString();
                        tot_trans=j.getProperty(5).toString();

                    }

Till here it is working... but after this line I get null pointer exception

            cards.setText(totactive);
            Comm.setText(totcomm);
            inactive.setText(totinactive);
            shops.setText(totshops);
            trans.setText(tot_trans);


        }else {
        builder.setMessage("Could not reach the Server. Please try again.").setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Intent mainActivity = new Intent(getBaseContext(),MainActivity.class);
                startActivity(mainActivity);
                StatsActivity.this.finish();
            }
        }).create().show();
    }

    }
}

I'm getting exactly at the line where I'm setting values in layout. Would anybody help me out to get rid of this? This is the error log

use your brain(or at least, try to) ... assumption: shop is null(with debbuger you can be sure) ... question why? never asigned - not true ... obviously , `findViewById(R.id.shops)` returns `null` ... why ... the only cause can be: there is no such view on given layout ... solved ... also asked bazillion times [example](http://stackoverflow.com/questions/30842769/app-crashes-when-opening-please-help-me) — Selvin, Jun 15 '15 at 15:16
@Selvin, If your comment answers this question, please post it as answer. Thanks for helping others — blueware, Jun 15 '15 at 15:21
@ASP and? https://github.com/android/platform_frameworks_base/blob/master/core/java/android/widget/TextView.java#L3923 `TextView.setText(null)` is valid(will not throw an exception) ... so (obviously) `totactive` can be null — Selvin, Jun 15 '15 at 15:56
Dear selvin,i printed all values nothing is shown null...all are getting printed.......i'm getting error only while setting edit text values. — sanjana, Jun 15 '15 at 17:58

The error is here..

setContentView(R.layout.activity_main);

it should be the layout(in my case statsactivity) where we are setting values.Since i'm a newbie ...it might be a stupid mistake assaid by @selvin. But it should not flag nullpointer exception it could have been better had it flagged relevant xml layout error
