I am trying to close progress dialog after exception occurred, but my current scenario is not allowing me to.

I have 3 classes:

1. MainActivity
2. SecondClass
3. ThirdClass

From **MainActivity** I am running a task using AsyncTask and shows a progress dialog, while a task is done in background.

```
@Override
public void onCreate(Bundle savedInstanceState) 
{

 // my code ...

 BackgroundTask bt = new BackgroundTask();
 bt.execute();

}
private class BackgroundTask extends AsyncTask<Void, Void, Void> 
{
   private ProgressDialog PD;

   @Override
   protected void onPreExecute() 
   {
      PD =  new ProgressDialog(getActivity());
      PD.setMessage("Performing background tasks...");
      PD.setCancelable(false);
      PD.show();
   }

   @Override
   protected Void doInBackground(Void... arg0) 
   {
      // call SecondClass's getMyPhotos method to perform some tasks
      // ...

      return null;
   }

   protected void onPostExecute(Void... arg0)
   {
      Log.i("MainActivity", "--called--");
   }
}

```

My **SecondClass** is simple Java class with some methods

```
public class SecondClass
{
   // ....
   public void getMyPhotos()
   {
      // from here I call ThirdClass's internetRelatedStuff method
   }
}

```

And lastly in **ThirdClass** I am doing some internet related stuff in AsyncTask:

```
public class ThirdClass
{
   // ....
   public void internetRelatedStuff()
   {
      try
      {
         // again some other stuff...

         // LoadImage asyncTask        
         LoadImage loadImg = new LoadImage();
         loadImg.execute();
      }
      catch(Exception e)
      {
          if(e.getErrorCode() == 34)
          {
             // if I get an exception here, how am I suppose to close close Progress dialog
             // of MainActivity
          }
      }
   }    

private class LoadImage extends AsyncTask<.......> 
{
 // .....
}   

}

```

So in my ThirdClass's try/catch, is it possible if an exception occurred, I can close the Progress dialog which is showing from MainActivity?
