Dialog/orientation change memory leaks...

Well, today I kept battling a memory leak in my opening screen for Perspective when rotating the phone.  A quick search yielded plenty of references to orientation changes when rotating.  There were quite a few work arounds, but I found a simple one that really made it simple for me so I figured I'd share.

To fix the problem in my PopDialog class that extends a Dialog, I added a

static PopDialog pd=null;  

Then I added this just after the onCreate

  pd=PopDialog.this;
  MainActivity.opened=true;

and finally I added this method

 public void dismissing(){
if(pd.isShowing()){pd.dismiss();}

}

OK, that's the hard part.  Now in my main activity, I referenced it like this

 PopDialog popdialog;
 private static boolean opened=false;

after onCreate in that activity

popdialog=new PopDialog(this);

and finally in the onPause

@Override
protected void onPause() {
super.onPause();
if(opened){ popdialog.dismissing();}


}
I forgot, add this to the button you call the Dialog from because sometimes it doesn't call onCreate.

opened=true;  

This way when rotating, it always has the proper reference to the active dialog and calls to dismiss it destroying it.  I had to update it a bit by adding the opened in there.  This is won't let it call dismiss before the dialog is created.
