I've developed a Application that i'm going to send data from the phone to the server by Json, to do this i use Volley Library in Android.
but i can not send data to the server!
my simple php code :
$name = $_GET["name"];
$j = array('name' =>$name);
echo json_encode($j);
my java code :
private void makeJsonObjectRequest() {
        mRequestQueue = Volley.newRequestQueue(this);
        String url = "http://my-site-name/sampleGET.php";
        StringRequest jsonObjReq = new StringRequest(Request.Method.GET, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d("result:", response);
                        Toast.makeText(getApplicationContext(), response, Toast.LENGTH_SHORT).show();
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d("err", "Error: " + error.getMessage());
                makeJsonObjectRequest();
            }
        }) {
            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<>();
                params.put("name", "json");
                return params;
            }
        };
        mRequestQueue.add(jsonObjReq);
    }
