AlertActivity now behaves as a dialog for accessibility purposes.

/**

        }

    }

    @Override

    public boolean dispatchPopulateAccessibilityEvent(AccessibilityEvent event) {

        event.setClassName(Dialog.class.getName());

        event.setPackageName(getPackageName());

        ViewGroup.LayoutParams params = getWindow().getAttributes();

        boolean isFullScreen = (params.width == ViewGroup.LayoutParams.MATCH_PARENT) &&

                (params.height == ViewGroup.LayoutParams.MATCH_PARENT);

        event.setFullScreen(isFullScreen);

        return false;

    }

    /**

     * and installing the alert's content.
