The method getWindow() is undefined for the type AlertDialog.Builder

eula is the Builder, not the dialog itself. Try:

final AlertDialog eulaDialog = eula.create();
eulaDialog.show();
WindowManager.LayoutParams lp = eulaDialog.getWindow().getAttributes();
lp.dimAmount = 0.0F;
eulaDialog.getWindow().setAttributes(lp);
eulaDialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

I have made a very healthy career out of architecting, implementing and maintaining servers, networks, firewalls, databases, workstations, etc, etc, etc. But, at the end of the day; when I turn on my personal laptop: I code. I got serious about coding with the release of the Android handsets. Serious by my standards meant inquisitive or intrigued ... I have always written code in one form or another, but I really, really long for a development job. I grew up when id Software was in its infancy and writing games was the coolest thing you could do. I started through Head First Java. It's a great book. I also purchased and started watching O'Reilly's Developing Android Apps with Java video series. Also good. The problem is I don't learn in that way. I learn by doing, but I really had nothing to do. I was approached out of the blue in January 2011 by a Realtor based in NY. He wanted an application that would allow him to send a large number of people an SMS message. Direct Marketing. Ugh. I hadn't touched Android or Java in almost a year. But thanks to Stuttering John Smith here I am. Almost 1 month into the release of my own app I have 1,500 downloads with 500 active installations. Thank you John for giving me something to do.

Idea taken from Android: Blurring and dimming background windows from dialog. I'm having trouble getting the content under my dialog to blur. When calling eula.getWindow() I receive this error:

The method getWindow() is undefined for the type AlertDialog.Builder

The eula is displayed with this bit of code from the main activity:

    EulaHelper.showEula(false, this);

Any help is greatly appreciated.

    public static void showEula(final boolean accepted, final FragmentActivity activity) {
    AlertDialog.Builder eula = new AlertDialog.Builder(activity)
            .setTitle(R.string.eula_title)
            .setIcon(android.R.drawable.ic_dialog_info)
                .setMessage(activity.getString(R.raw.eula))
            .setCancelable(accepted);

    if (accepted) {
        // If they've accepted the EULA allow, show an OK to dismiss.
        eula.setPositiveButton(android.R.string.ok,
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                });
    } else {
        // If they haven't accepted the EULA allow, show accept/decline buttons and exit on
        // decline.
        eula
                .setPositiveButton(R.string.accept,
                        new android.content.DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int which) {
                                setAcceptedEula(activity);
                                dialog.dismiss();
                            }
                        })
                .setNegativeButton(R.string.decline,
                        new android.content.DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int which) {
                                dialog.cancel();
                                activity.finish();
                            }
                        });
    }
    eula.show();
    WindowManager.LayoutParams lp = eula.getWindow().getAttributes();
    lp.dimAmount = 0.0F;
    eula.getWindow().setAttributes(lp);
    eula.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
