title: how to get lng and lat from JSON file
body: <p>I would like to get "lat" and "lng" from my JSON file and add to one array that keeps GeoPoint. I was trying to do it like that but it is not working for me : </p>
  
  <pre><code>protected List&lt;GeoPoint&gt; JsonArray(){
          List&lt;GeoPoint&gt; endp = new ArrayList&lt;GeoPoint&gt;();
  
          try{
          JSONObject obj = new JSONObject(json);
          JSONArray steps = obj.getJSONArray("routes");
          for(int i=0;i&lt;steps.length();i++){
              JSONObject temp = steps.getJSONObject(i);
              JSONObject ele = temp.optJSONObject("steps").optJSONObject("end_location");
              ele.getJSONObject("lat");
              ele.getJSONObject("lng");
  
              double lat = Double.parseDouble(ele.getJSONObject("lat").toString());
              double lng = Double.parseDouble(ele.getJSONObject("lng").toString());
              endp.add(new GeoPoint((int)(lat *1E6),(int)(lng * 1E6)));
  
          }
  
  
  
          }catch (JSONException e) {
              // TODO: handle exception
          }
          return endp;
      }
