Just out of curiosity, why? This is more work and more complicated,
especially with the saving and restoring the state.

Thanks ... yes, I had already read that.

I decided to manage the Dialog myself, using dismiss() and show() and
it works nicely now.

One thing I had not realised is that a dismiss() is needed in
OnDestroy() ... without that,
a show() in OnCreate() will not work. That was the root cause of my
trouble.

The dialog itself does not have an ID - it's for th Activity to map to the
correct dialog it manages.
See this and come back with any questions:

Thanks ... this is very helpful. I am indeed using Dialog.show(). If I
move
to Activity.showDialog(int) it's not clear to me how to get hold of
the
id of my Dialog, since I don't specify one when creating it. Here is
the code snippet:

// Create a general message box

AlertDialog.Builder messagebuild = new AlertDialog.Builder(this);
messagebuild.setPositiveButton("OK", this);
message = messagebuild.create();

// Create the message handler which will handle messages
messageHandler = new Handler() {
  @Override
  public void handleMessage(Message msg) {
 if(msg.what == SAVEFILEERROR) {
message.setTitle("Error");
message.setMessage("this error");
// replace message.show()
//message.show();
message.getOwnerActivity().showDialog(id???);
  }
  }
   };

How do I assign or retrieve the id of the Dialog created by
AlertDialog.Builder?

Thanks!
