title: Wait for result of Async Volley request and return it
body: <p>Below is a method in which I am trying to retrieve an user object by calling getSelf(). Problem is that the result is always null since the Volley request has not finished at the time of returning the result. I'm somewhat new to async processes, so I am not sure of the best way to have the method wait for the result of the API call to return the UserBean object. Can anyone give me some help?</p>
  
  <pre><code>public UserBean getSelf(String url){
  
      RpcJSONObject jsonRequest = new RpcJSONObject("getSelf", new JSONArray());
  
      JsonObjectRequest userRequest = new JsonObjectRequest(Request.Method.POST, url, jsonRequest, 
          new Response.Listener&lt;JSONObject&gt;() {
              @Override
              public void onResponse(JSONObject response) {
  
                  String result;
                  try {
                      result = response.getString("result");
                      Gson gson = new Gson();
                      java.lang.reflect.Type listType = new TypeToken&lt;UserBean&gt;() {}.getType();
  
                      //HOW DO I RETURN THIS VALUE VIA THE PARENT METHOD??
                      userBean = (UserBean) gson.fromJson(result, listType);
  
                  } catch (JSONException e) {
                      e.printStackTrace();
                  }
  
              }
          }, new Response.ErrorListener() {
              @Override
              public void onErrorResponse(VolleyError error) {
                 Log.e("Error:", error.toString());
                 finish();
              }
          }
      );
  
      this.queue.add(userRequest);
  
  
      return userBean;
  
  }
