 private void postUsingVolley() {
    String tag_json_obj = "json_obj_req";

    final ProgressDialog pDialog = new ProgressDialog(this);
    pDialog.setMessage("posting...");
    pDialog.show();

    final String mVendorId = DeviceDetails.getInstance(mContext).getVendor_id();
    String mUserId = UserModel.getInstance(mContext).getUser_id();

    final HashMap postParams = new HashMap();
    sendFeedbackParams.put("key1", value1);
    sendFeedbackParams.put("key2", value2);
    sendFeedbackParams.put("key3", value3);

    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
            ApplicationData.POST_URL, new JSONObject(postParams),
            new com.android.volley.Response.Listener() {

                @Override
                public void onResponse(JSONObject response) {
                    //Log.d("TAG", response.toString());
                    try {
                        //Toast.makeText(mContext, response.getString("message"), Toast.LENGTH_LONG).show();
                        Toast.makeText(mContext, "Thank you for your post", Toast.LENGTH_LONG).show();

                        if (response.getBoolean("status")) {
                            pDialog.dismiss();
                            finish();
                        }
                    } catch (JSONException e) {
                        Log.e("TAG", e.toString());
                    }
                    pDialog.dismiss();
                }
            }, new com.android.volley.Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            //VolleyLog.d("TAG", "Error: " + error.getMessage());
            pDialog.dismiss();
            if (isNetworkProblem(error)) {
                Toast.makeText(mContext, "Internet Problem", Toast.LENGTH_SHORT).show();

            }
        }
    }) {

        @Override
        public String getBodyContentType() {
            return "application/json; charset=utf-8";
        }

        @Override
        public Map getHeaders() throws AuthFailureError {
            return getRequestHeaders();
        }
    };

    jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(8000, 0, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
    // Adding request to request queue
    AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
}

Use Volley like this,... It is working for me.
