title: How can I kill a custom dialog - before it's been created?
body: <p>Clearly I have a case of what I like to call "chicken or the egg" syndrome.  I am trying to find a way to kill an alert dialog which isn't created until the end of the process.</p>
  
  <p>What I am trying to do: When asked "Do you want to RE-DOWNLOAD this gallery?", I want to KILL the underlying pop-up (alert/builder) when I get a "Yes" answer.  But not when I get a "No" answer.  In other words, I would like to put an alert.dismiss() in there ... but I can't, because it's not created until the end of the process.</p>
  
  <p>Does that make sense?  I'm racking my brain on this trying to find another way to present this to a user.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>public void showGalleriesDialogue(String galleriesArray) {
  Log.v("Status","Ran alert dialogue routine."); 
  final CharSequence[] items = TextUtils.split(galleriesArray, "\\^");
  
  final AlertDialog.Builder builder = new AlertDialog.Builder(MainMenu.this);
  builder.setTitle("Choose a Gallery to download:");
  
  builder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int item) {
          final String galleryToDownload = (String) items[item].toString();
  
          // Check to ensure that this doesn't all ready exist            
          File checkExisists = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/pm-pvault/" + galleryToDownload);
          Log.v("Status","Checking to ensure that '"+checkExisists+"' does not exist."); 
          if(checkExisists.exists()) {
                  AlertDialog.Builder existsBuilder = new AlertDialog.Builder(MainMenu.this);
                  existsBuilder.setTitle("But wait!");
                  existsBuilder.setMessage("This gallery already exists. Do you want to RE-INSTALL it?")
                         .setCancelable(false)
                         .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                             public void onClick(DialogInterface dialog, int id) {
                                  // Preview stuff, then go get it.
                                 GlobalDataStore.retrycount = 0;
                              preview(galleryToDownload);
                                 }
                         })
                         .setNegativeButton("No", new DialogInterface.OnClickListener() {

                                  dialog.cancel();
                             }
                         });
                  AlertDialog existsAlert = existsBuilder.create();
                  existsAlert.show();
              }
          //OR ELSE
