                break;

            case 1:
                // clear all images in the list
                removeDialog(0);
                break;


            }

        };
    };

You are trying to show your Toast in onCreateDialog method and it's conditioned on counter!=1. onCreateDialog is not called when you show dialog but only when you create it. It's only called once so Toast never appear.

I believe that you are trying to run the thread, show progress when it's running and dismiss it and show Toast when it's complete. If that's the case, much simpler and correct way to achieve your goal is to use AsyncTask. Read about it here: http://developer.android.com/reference/android/os/AsyncTask.html
