How to handle screen orientation change when progress dialog and background thread active?

Question

My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler. This all works fine, exc

If you're struggling with detecting orientation change events of a dialog INDEPENDENT OF AN ACTIVITY REFERENCE, this method works excitingly well. I use this because I have my own dialog class that can be shown in multiple different Activities so I don't always know which Activity it's being shown in. With this method you don't need to change the AndroidManifest, worry about Activity references, and you don't need a custom dialog (as I have). You do need, however, a custom content view so you can detect the orientation changes using that particular view. Here's my example:

Setup

public class MyContentView extends View{
    public MyContentView(Context context){
        super(context);
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig){
        super.onConfigurationChanged(newConfig);

        //DO SOMETHING HERE!! :D
    }
}

Implementation 1 - Dialog

Dialog dialog = new Dialog(context);
//set up dialog
dialog.setContentView(new MyContentView(context));
dialog.show();

Implementation 2 - AlertDialog.Builder

AlertDialog.Builder builder = new AlertDialog.Builder(context);
//set up dialog builder
builder.setView(new MyContentView(context));        //Can use this method
builder.setCustomTitle(new MycontentView(context)); // or this method
builder.build().show();

Implementation 3 - ProgressDialog / AlertDialog

ProgressDialog progress = new ProgressDialog(context);
//set up progress dialog
progress.setView(new MyContentView(context));        //Can use this method
progress.setCustomTitle(new MyContentView(context)); // or this method
progress.show();
