Android Kotlin Volley Post String with multiple variable


I would like to use POST method to post a string of username and password to a php page but I couldn't find the solution. Thus, i try to use JSONRequest method, but it always gave me the result of Response.ErrorListener. Please help to solve it.

Code for StringRequest:

UserNamePassword = "Name=aaa&Password=bbb"

val queue = Volley.newRequestQueue(this)

val stringRequest = StringRequest(Request.Method.POST, url,
        Response.Listener<String> { response ->
        // Display the first 500 characters of the response string.
        }, Response.ErrorListener { println("That didn't work!") })

// Add the request to the RequestQueue.

Code for JSONRequest:

val jsonobj = JSONObject()

jsonobj.put("Name", "aaa")
jsonobj.put("Password", "bbb")

val que = Volley.newRequestQueue(this)
val req = JsonObjectRequest(Request.Method.POST,url,jsonobj,
            Response.Listener {
                response ->
            }, Response.ErrorListener {
                println("Error rrrrrrrrrrrrrrr")

Result from Android Studio

Trying it

}, Response.ErrorListener { error: VolleyError ->
    println("Error $error.message")

we have the follow error message as you said us

06-07 20:46:17.317 10064-10064/com.gph.radiobutton I/Choreographer: Skipped 47 frames!  The application may be doing too much work on its main thread.

Then we can see that the problem is another, e.g., an error do occur on your web service and you don't send them as a valid json to the application again.
