Question

i need to pass the multiple JSON object fields in single request to StringRequest property of Volley library.I mentioned the request body below for better understanding.

{
"DeviceInfo": {
    "Os": "Android",
    "Access": "true"
  },
  "FirstName": "test",
  "LastName": "test",
  "USerName": "test"
