  <p>Here is the section of code where I call the activity:</p>
  
  <pre><code>public void onItemClick(AdapterView parent, View v, int position, long id)
   {
       Log.i(tag,"item clicked! [" + feed.getItem(position).getTitle() + "]");
  
       Intent itemintent = new Intent(this,com.acithium.rss.ShowDescription.class);
       //Intent itemintent = new Intent();
       //itemintent.setClassName("com.acithium.main", "com.acithium.rss.ShowDescription");
       Bundle b = new Bundle();
       b.putString("title", feed.getItem(position).getTitle());
       b.putString("description", feed.getItem(position).getDescription());
       b.putString("link", feed.getItem(position).getLink());
       itemintent.putExtra("android.intent.extra.INTENT", b);
  
       startActivityForResult(itemintent,0);
   }
  </code></pre>
  
  <p>And here is new activity class that is called:</p>
  
  <pre><code>public class ShowDescription extends Activity

          String theStory = null;
  
  
          Intent startingIntent = getIntent();
  
  
          if (startingIntent != null)
