                        Inner.put("qid",crsrallansr.getString(crsrallansr.getColumnIndex("qid")));
                        Inner.put("qstn",crsrallansr.getString(crsrallansr.getColumnIndex("qid")));

                    xx++;
                }

Fixed the problem using StringRequest like :

reqPostanswers = new StringRequest(Request.Method.POST, url,new Response.Listener<String>() {

            @Override
            public void onResponse(String response) {
                Log.i("posting info :",response.toString());
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                //Log.i("posting error  :",error.toString());
            }
        }){
            @Override
            protected Map<String, String> getParams()
            {
                Map<String, String>  params = new HashMap<String, String>();
                params.put("user", thisuser);
                params.put("answers",jsData.toString());
                params.put("lickey","1761");
                return params;

            }

        };
        answerpostQueue = Volley.newRequestQueue(getApplicationContext());
        answerpostQueue.add(reqPostanswers);

At the server side ( php ); the code is as follows :

        $answers=json_decode($_POST['answers']);
        
        foreach ($answers as $answer) {
            $answer=json_encode($answer);
            echo $answer;
            $answer=json_decode($answer);
            $uname=$_POST['user'];
            $qid=$answer->qid;
            $result=$answer->result;
            $qstn=$answer->qstn;
