Answer 1

first your json data:

JSONObject js = new JSONObject();
try {
    JSONObject jsonobject_one = new JSONObject();

    jsonobject_one.put("type", "event_and_offer");
    jsonobject_one.put("devicetype", "I");

    JSONObject jsonobject_TWO = new JSONObject();
    jsonobject_TWO.put("value", "event");
    JSONObject jsonobject = new JSONObject();

    jsonobject.put("requestinfo", jsonobject_TWO);
    jsonobject.put("request", jsonobject_one);


    js.put("data", jsonobject.toString());

}catch (JSONException e) {
        e.printStackTrace();
}

then your json request:

JsonObjectRequest jsonObjReq = new JsonObjectRequest(
        Request.Method.POST,url, js,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());

                msgResponse.setText(response.toString());
                hideProgressDialog();
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());
                hideProgressDialog();
            }
        }) {

    /**
     * Passing some request headers
     * */
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
         HashMap<String, String> headers = new HashMap<String, String>();
         headers.put("Content-Type", "application/json; charset=utf-8");
        return headers;
    }

Notice the header

and if you want to test in localhost use below code and set your url to connect your localhost server and ip address: below code put all of your request in a text file, i tried it and it works

<?php
file_put_contents('test.txt', file_get_contents('php://input'));
?>

Why is it required to send charset=utf-8 and not just 'application/json' – Abscond
