            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    try {
                        JSONArray jsonArray = new JSONArray(response);
                        for (int i = 0; i < jsonArray.length(); i++) {
                            JSONObject object = jsonArray.getJSONObject(i);
                            String jobname = object.getString("jobname");
                            String jobdetails = object.getString("jobdetails");
                            String startdate = object.getString("startdate");
                            String enddate = object.getString("enddate");
                            String posts = object.getString("posts");
                            String govtfees = object.getString("govtfees");
                            String appfees = object.getString("appfees");
                            String documents = object.getString("documents");
                            String declartion = object.getString("declartion");


                            AllJobsModel alljobsName = new AllJobsModel(jobname, jobdetails, posts, startdate, enddate, govtfees, appfees, documents, declartion);
                            alljobsName.setJobName(jobname);
                            alljobsName.setJobDetails(jobdetails);
                            allJobs.add(alljobsName);


                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                        AndroidUtil.showToast(getApplicationContext(),e.toString());
                    }
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
        }
    }){
        @Nullable
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String, String> params = new HashMap<>();
            params.put("id","1");
            return params;
        }

    };
        RequestQueue queue=  Volley.newRequestQueue(MainActivity.this);
        queue.add(stringRequest);


    }
PHP
<?php

    require_once "conn.php";
    require_once "validate.php";
    $id = $_POST['id'];
    $sql = "SELECT * from all_jobs WHERE id ='$id'";
    $result=mysqli_query($conn, $sql);
    $all_jobs= array();
    while($row=mysqli_fetch_array($result)){
        
        
        $index['jobname']=$row['jobname'];
        $index['posts']=$row['posts'];
        $index['startdate']=$row['startdate'];
        $index['enddate']=$row['enddate'];
        $index['govtfees']=$row['govtfees'];
        $index['appfees']=$row['appfees'];
        $index['documents']=$row['documents'];
        $index['declartion']=$row['declartion'];
        $index['jobdetails']=$row['jobdetails'];
        

        array_push($all_jobs, $index);
    }
    echo json_encode($all_jobs)
?>

"json error can not covert string to json array // something like this."
It would be much simpler, and far more useful, to copy and paste the exact error message.

Sorry, but we can't help you - if you read the error message, the problem is with the JSON data not matching the classes it is being deserialised into:

You need to use your IDE debugger to look at exactly what is being processed and what it is being converted into.
And we have no access to either of those.
