IF you want to over come from these problem than you have to make check that the json or string exit in the response or not just like

JSONObject jsonObject = new JSONObject(respons);///Here response is your response

if(jsonObject.has("alert"))
{
 JSONObject alert = json.getJSONObject("alert");

 if(alert.has("long_msg"))
 {
  String _longMsg = alert.getString(Constansts.PARSE.NOTIFICATION.LONG_MSG);
 }

if(alert.has("short_msg"))
 {
  String _shortMsg = alert.getString(Constansts.PARSE.NOTIFICATION.SHORT_MSG);
 }

if(alert.has("title"))
 {
  String _title = alert.getString(Constansts.PARSE.NOTIFICATION.TITLE);
 }
}

It will never throw the exception....which are you getting now

Geet the JSON under alert first and then under that reference the other string values

JSONObject alert=json.getJSONObject("alert");;
String _title = alert.getString(Constansts.PARSE.NOTIFICATION.TITLE);

As per the JSON

"alert": { 
   "long_msg": "Thank you for downloading PHARMAPLUS APP, if you found our APP helpful please rate us five star on play store", 
   "short_msg": "Welcome to PHARMAPLUS", 
   "title": "Thank you" 
 }

Here alert is a JSONObject. And the values title, long_msg, short_msg are inside alert

So, you need to modify this part of code

if (json.has("alert")) {
     String alert = json.getString("alert");
     String _title = json.getString(Constansts.PARSE.NOTIFICATION.TITLE);
     String _shortMsg = json.getString(Constansts.PARSE.NOTIFICATION.SHORT_MSG);
     String _longMsg = json.getString(Constansts.PARSE.NOTIFICATION.LONG_MSG);

into

if (json.has("alert")) {
     JSONObject alert = json.getJSONObject("alert");
     String _title = alert.getString(Constansts.PARSE.NOTIFICATION.TITLE);
     String _shortMsg = alert.getString(Constansts.PARSE.NOTIFICATION.SHORT_MSG);
     String _longMsg = alert.getString(Constansts.PARSE.NOTIFICATION.LONG_MSG);
