You can get the parent menu to which the current path belongs to using the function "menu_link_get_preferred". Lets say you have created a menu with name "ANDROID" and you have listed a page/node under that menu. The following code returns true when you visit that page/node. You can use this technique to selectively display certain blocks only on some pages that belong to a target menu.
<?php $menu = menu_link_get_preferred(current_path(), 'menu-android'); return ($menu['menu_name'] == 'menu-android'); ?>
Place this code under the block's visibility criteria as shown bellow in Fig-1. The module "PHP filter" needs to be enabled for this to work.
