Send post data to server using Volley android

Question

I am trying to send some data to the server using the Volley library.

   private void registerUser(final String email, final String username,

This is the solution. I had to use the JsonObjectRequest class and not the StringRequest on. What JsonRequest does is that it converts your HashMap key-value pairs into a JSON Format.

    private void registerUser(String email_address,String username, String 
    password) {
    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();
    String location = getResources().getConfiguration().locale.getCountry();
    final HashMap postParams = new HashMap  
    ();
    postParams.put("username", username);
    postParams.put("email", email_address);
    postParams.put("password", password);
    postParams.put("location", location);



    Response.Listener  listener;
    Response.ErrorListener errorListener;
    final JSONObject jsonObject = new JSONObject(postParams);

    JsonObjectRequest jsonObjReq = new 
    JsonObjectRequest(AppConfig.URL_REGISTER, jsonObject,
            new com.android.volley.Response.Listener() {

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

                        if (response.getString("status").equals("success")){


                            session.setLogin(true);


                            pDialog.dismiss();
                           Intent i = new 
        Intent(RegisterActivity.this,Welcome.class);
                           startActivity(i);

                            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();

        }
    }) {

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


    };


    // Adding request to request queue
    AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
