Answer 1

int count;

 private void attemptConnect() 
 {
   count = 0;
   str_lang = "English";
   str_wait = "Plaese Wait";

   new AllQuestion().execute();

}


private class AllQuestion extends AsyncTask<String, String, String> {
    ProgressDialog pg;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();

        pg = new ProgressDialog(LanguageActivity.this);
        pg.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        pg.setMessage(str_wait);
        pg.setCancelable(false);
        pg.show();
    }

    @Override
    protected String doInBackground(String... strings) {
        try {
            SoapObject soapObject = new SoapObject(AppConstant.NAMESPACE, AppConstant.QUESTION_SOAP_METHOD); 
            soapObject.addProperty("language", str_lang);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(soapObject);

            HttpTransportSE se = new HttpTransportSE(AppConstant.webUrl);
            se.call(AppConstant.QUESTION_SOAP_ACTION, envelope);


            Object responce = envelope.getResponse();
            Log.d("Question List:=>>", "" + responce);

            return responce.toString();
        } catch (Exception e) {
            e.printStackTrace();
            pg.dismiss();
            return null;
        }
    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);

        if (pg.isShowing()) {
            pg.dismiss();
            Log.i(TAG, s);

            if (s != null || !s.equalsIgnoreCase("")) {
                try {
                    JSONArray array = new JSONArray(s);

                    for (int i = 0; i < array.length(); i++) {
                        JSONObject obj = array.getJSONObject(i);

                        String queId = obj.getString(TAG_QID);
                        String que = obj.getString(TAG_QUE);
                        String str_Opt = obj.getString(TAG_OPT);

                        question = new Question(queId, que, str_lang, str_catId, str_Opt, manager.getDateTime());
                        helper.insertQuestion(question);
                    }
                    count++;
                    if (count < 5) {
                        if (count == 1) {
                            str_lang = "German";
                            str_wait = "bitte warte einen Moment";

                                new AllQuestion().execute();
                        }
                        if (count == 2) {

                            str_wait = "per favore aspetta un momento";

                                new AllQuestion().execute();
                        }
                        if (count == 3) {
                            str_lang = "Chinese";
                            str_wait = "请稍候";

                                new AllQuestion().execute();
                        }
                        if (count == 4) {

                            str_wait = "patientez s'il-vous-plait";

                                new AllQuestion().execute();

                    }
                    Log.d("All Question:-", question.toString());

                } catch (JSONException e) {

                }
