Problem :

As you can see in your logcat the response that you get from the server is success_access{"access":"PA001","password":"123","fullname":"ARCADE","branch":"HQ","section":"HQ"}

First, this is not a valid JSON. Also, that is the value of the response variable. Now, your response.equals("success_access") will never return true, and hence the code control will never enter the if block.

Solution :

Ideally, there should be no extra string like success_access, insted your response should be a JSON object ALWAYS containing one specified field (the result feild for example). To show success, your JSON will look something like :

{
    result : "success_access",
    /* other parameters down here */
} 

And in case of failure :

{
    result : "access_failed"
} 

And then your code should convert the respose string into a JSON (your server code should make sure that it returns a valid JSON always) check for the value of the result field and proceed further.

Quick Fix :

Change your code to :

  ....
  Log.e(TAG, "Response is = " + response);
  String result = response.replace("{.*}","");
  String jsonString = response.replace(result, "");

  if(result.equals("success_access")){
    try {
            JSONObject jsonObject = new JSONObject(jsonString);
    ....
