title: parsing data from JSON using Volley in Android
body: <p>I tried parsing JSON data from "<a href="https://api.instagram.com/v1/media/popular?client_id=" rel="nofollow">https://api.instagram.com/v1/media/popular?client_id=</a>"
              + clientId; or any other url,  in a tons of different ways! Used couple of JSONParsers, tutorials, readers .. everything, but still can't to get anything from those urls. Now I am using Volley library and still can't get it to work,  here is my code and everything you need, if anyone has any ideas , please share them. </p>
  
  <pre><code>public  void LoadPictures()   {
      mRequestQueue =  Volley.newRequestQueue(this);
      mRequestQueue.add(new JsonObjectRequest(urlInst, null,
              new Listener&lt;JSONObject&gt;() {
                  @Override
                  public void onResponse(JSONObject response) {
                      try {
                          parseJSON(response);
                      } catch (JSONException e) {
                          // TODO Auto-generated catch block
                          e.printStackTrace();
                      }
                  }
              }, new ErrorListener() {
          @Override
          public void onErrorResponse(VolleyError error) {
              error.printStackTrace();
          }
      }));
  </code></pre>
  
  <p>this is my parseJSON method:</p>
  
  <pre><code> private  void parseJSON(JSONObject json) throws JSONException{      
       // JSONObject value = json.getJSONObject("value");
   JSONArray items = json.getJSONArray("data");
   for(int i=0;i&lt;items.length();i++) {
       JSONObject c=(JSONObject) items.get(i);
           JSONObject user = c.getJSONObject("user");
       String name= user.getString("username");
       JSONObject img=c.getJSONObject("images");
           JSONObject thum=img.getJSONObject("thumbnail");
           String urlOfPic = thum.getString("url");  
           PhotoInst photoData=new PhotoInst (i, urlOfPic, name);
           photos.add(photoData);
       }
  </code></pre>
  
  <p>this is JSON data I was supposed to get :  </p>

  <p>when I try putting random Toasts to see where is the problem, I can see the onResponse in my method LoadPictures isn't called at all? Where am I failing ? am I just overseeing something small or something else? </p>
