The contents of /data/app and /system are private implementation details of
the platform and you should never touch them directly or make assumptions
about what they contain.
The PackageManager is the API for accessing all information about installed
applications. Please don't directly access .apks. (And in the code posted
previously for querying the main activities, there is absolutely no need for
the "INSTALL_PACKAGE" permission for this. In fact, third party apps can't
get that permission, period.)
