          JSONParser jParser = new JSONParser();
  
          // Getting JSON from URL
          JSONObject json = jParser.getJSONFromUrl(url);
          return json;
      }
       @Override
       protected void onPostExecute(JSONObject json) {
          try {
                  // Getting JSON Array
  
                  // Storing  JSON item in a Variable
                  Url = http://icons.iconarchive.com/icons/benjigarner/softdimension/48/
                  String icon = json.getString("icon"); //URL String
                  String ImageUrl = Url + Icon;
  
                  //Function to get image from URL - First method
                  Drawable MyImage = loadloadImageFromURL(ImageUrl);
  
                  //Function to get image from URL - Second method
                  Bitmap MyImage = getBitmapFromURL(ImageUrl);
                  //Third Method

                  ImageView Image = (ImageView) rootView.findViewById(R.id.imgMainWeather);   Image.setImageBitmap(MainActivity.WeatherImage);
  
                  } catch (JSONException e) {
              e.printStackTrace();
          }
       }
      //Function First Method
      public static Drawable loadImageFromURL(String url) {
      try {
          InputStream is = (InputStream) new URL(url).getContent();  // While Debugging After this line Error occurs
          Drawable d = Drawable.createFromStream(is, "src name");
          return d;
      } catch (Exception e) {
          Log.i("Image", "No Image");
          return null;
      }

          HttpURLConnection connection = (HttpURLConnection) url.openConnection();
          connection.setDoInput(true);
          connection.connect();
          InputStream input = connection.getInputStream(); // While Debugging After this line Error occurs
          Bitmap MyBitmap = BitmapFactory.decodeStream(input);
