                        }

                    }
                }

                // add item to the list
                _feed.addItem(_item);
            }

        } catch (Exception e) {
        }

        // Return the final feed once all the Items are added to the RSSFeed
        // Object(_feed).
        return _feed;
    }

}

By changing this block of code  i got title  and description but no image obtained 
// Get the required elements from each Item
                for (int j = 0; j < clength; j = j + 1) {


please help me in obtaining  it  or can we have any other ways to do thi application without rss feeds
