What's the same in Retrofit POST like StringRequest in Volley?

For example, I have Volley code for StringRequest here.
What do we use to achieve the same result for Retrofit and how does interface look like in this case?
String url = getString(R.string.API_URL) + "/social/revoke-token";
StringRequest postRequest = new StringRequest
(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("RESPONSE FROM SERVER", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO: Handle error
}
}){

Delete request params URL Volley android

I have an API with a delete function like this:
http://localhost/v1/deletePost/:id
when i try in postman succeed by entering param in url ":id" like ../deletePost/37".
how to implement the "/:id" request in android using Volley library?

Here is a guide about how to use Volley Library
On the page Sending a Simple Request:
final TextView mTextView = (TextView) findViewById(R.id.text);
//...
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://www.google.com";
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});
// Add the request to the RequestQueue.queue.add(stringRequest);
Then you need to change GET to DELETE Request.Method.DELETE and the url for your url with the id http://localhost/v1/deletePost/37
Will be something like this:
String baseUrl ="http://localhost/v1/deletePost/";
String url = baseUrl + "3" //Here you change the ID, can put as variable
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.DELETE, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});

Volley PUT StringRequest not sent

I am sending a StringRequest using Volley to update a single record in mysql.The url is fine when i am sending the same request from postman i am getting result but when i send the request from android its not sent. I am not getting whats the issue.I am sendin two values that too iam sending it in url.Here is the code
StringRequest req = new StringRequest(Request.Method.PUT, url,new Response.Listener<String>() {
#Override
public void onResponse(String response) {
resp = Integer.parseInt(response.toString());
hidepDialog();
if(resp == 1){
Toast.makeText(getApplicationContext(),"Success",Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(getApplicationContext(),"Failure",Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});

Volley Error 500

I am trying to parse a url that i found online.
However when i try to use Volley standard way of sending a request, it keeps giving me the error of
BasicNetwork.performRequest: Unexpected response code 500 for http://www.mytransport.sg/content/mytransport/home/myconcierge/trafficcameras/jcr:content/par/cameras_slideshow.singleresult.html?cameraid=2704
However, when i try to access the url via my google chrome, it works fine without any problem.
This is my code:
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.e("RESPONSE", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// Error handling
error.printStackTrace();
}
});
// Add the request to the queue
Volley.newRequestQueue(this).add(stringRequest);

Volley sending multiple requests tracking

I was going through volley library documentation with the following example
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://www.google.com";
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
My question is if i add an other request(similar request i.e. StringRequest) request to the queue, how can i map my request to response since the response is asynchronous.
1request --> 1response.
2request --> 2response.
I don't have any priorities for request and should be done concurrently (not sequential requests).
