 // Create a dialog.
        AlertDialog dialog = new AlertDialog.Builder(this)
                .setPositiveButton(android.R.string.ok, null)
                .setMessage(R.string.secure_dialog_dialog_text)
                .create();

        // Make the dialog secure.  This must be done at the time the dialog is
        // created.  It cannot be changed after the dialog has been shown.
        dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,
                WindowManager.LayoutParams.FLAG_SECURE);

        // Show the dialog.
        dialog.show();
