Volley Web Service with Genson

[Ömer Korkmaz]

Hello friends. I am trying to pull data from json webservist with Volley and Genson. But it does not give an error, but it does not pull data. The problem is here. How can I access specificies data. How can I show ParseData.

1. private void GetData()

2. {
   RequestQueue queue = Volley.newRequestQueue(this);
   final String url = "https://api.github.com/users/mralexgray/repos";
   StringRequest postRequest = new StringRequest(Request.Method.GET, url,
   new Response.Listener<String>()
   {

3. @Override
   public void onResponse(String response) {
   // response
   Log.d("Response", response);
   ParseData(response);
   }
   },
   new Response.ErrorListener()
   {

4. @Override
   public void onErrorResponse(VolleyError error) {
   // error
   Log.d("Error.Response", error.getLocalizedMessage());
   }
   }
   )
   {
   };

5. queue.add(postRequest);

6. }

7. private void ParseData(String data)
   {
   Genson genson = new Genson();
   try {
   Servis[] persons = genson.deserialize(data, Servis[].class);
   }
   catch (Exception e)
   {
   String hata = e.getLocalizedMessage();
   }

8. }
9. public class Servis implements Serializable {
10. public String id;
11. public String name;
12. public String full_name;
13. }

Hi,

Your ParseData method is doing nothing with the deserialized persons, same in case of an exception during the parsing you don't seem to do anything with it, so I'm not sure what you expect to happen... Maybe start with adding some logging/printing statements to print the parsed data.

There doesn't seem to be any Genson related issue, I'd suggest you to look for more documentation on how Volley works and how to use it.

Perhaps your problem is that it's providing you the results asynchronously and you don't know how to get them in a synchronous manner. There seem to be plenty of resources on internet explaining how to do a synchronous request.
