Way to pass Long parameter in url request using volley

Question

Server is not accepting String parameters when making json object request (by post method) using volley, also in custom volley request it is required to pass a string Hash map in getParams() method i am having string as well as long values to be pass over there, Also tried by Uri class but there is also sting is required in appendQueryParameter(). i have used below links Link 1 Link 2 Link 3

Volley class

public class CustomRequest extends Request {

private Listener<JSONObject> listener;
private Map<String, String> params;

public CustomRequest(String url, Map<String, String> params,
                     Listener<JSONObject> reponseListener, ErrorListener errorListener) {
    super(Method.GET, url, errorListener);
    this.listener = reponseListener;
    this.params = params;
}

public CustomRequest(int method, String url, Map<String, String> params,
                     Listener<JSONObject> reponseListener, ErrorListener errorListener) {
    super(method, url, errorListener);
    this.listener = reponseListener;
    this.params = params;
}

protected Map<String, String> getParams()
        throws com.android.volley.AuthFailureError {
    return params;
}


@Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
    try {
        String jsonString = new String(response.data,
                HttpHeaderParser.parseCharset(response.headers));
        return Response.success(new JSONObject(jsonString),
                HttpHeaderParser.parseCacheHeaders(response));
       /* return Response.success(
                gson.fromJson(json, clazz), HttpHeaderParser.parseCacheHeaders(response));*/
    } catch (UnsupportedEncodingException e) {
        return Response.error(new ParseError(e));
    } catch (JSONException je) {
        return Response.error(new ParseError(je));
    }
}

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    Map<String, String> headers = new HashMap<>();
    String loginEncoded = new String(Base64.encode(("uictester:?f!T!ziX}.,(").getBytes(), Base64.DEFAULT));
    headers.put("Authorization", "Basic " + loginEncoded);
    return headers;
}

@Override
protected void deliverResponse(JSONObject response) {
    // TODO Auto-generated method stub
    listener.onResponse(response);
}

}

You first need to convert the long parameter to String using String.valueOf(long value) method and then put this param to the hashmap with its key. as:

params.put("key", String.valueOf(long value));
