Restrict getPackageInfo

[BlueMax]

Can you restrict 'PackageManager/getPackageInfo' to return 'NameNotFoundException' to prevent apps enumerating installed apps (and maybe bind this to getInstalledPackages whitelist)?

[getPackageInfo](http://developer.android.com/reference/android/content/pm/PackageManager.html#getPackageInfo%28java.lang.String, int%29) cannot be used to enumerate applications, since it returns information about one package only. Moreover, to prevent getting information about a single package would mean restricting a lot more PackageManager functions.

Just depends on the implementation. The Playstore dynamically pushes any relevant entry (package name) through it in realtime and updates the internal database accordingly. That's why getInstalledPackages misses the 'Installed' marker everywhere (including the 'All' apps tab).

Please note that there are many more methods to check if a package is installed.
It would be a performance hit if they were all hooked.
Nevertheless I guess the two hooked functions will probably cover most cases.

Note that these two new restrictions only work in AOSP mode (not in compatibility mode) and only for version 2.99.30 or later)

The new hooks are in version 2.99.30, can you please check if it works for Play store?

[BlueMax]

Yes, works properly.
