* Parallel implementation of certain {@link PackageManager} APIs that need to
* be exposed to native code.
* <p>These APIs are a parallel definition to the APIs in PackageManager, so,
* they can technically diverge. However, it's good practice to keep these
* APIs in sync with each other.
* <p>Because these APIs are exposed to native code, it's possible they will
* be exposed to privileged components [such as UID 0]. Care should be taken
* to avoid exposing potential security holes for methods where permission
* checks are bypassed based upon UID alone.

interface IPackageManagerNative {
* Returns a set of names for the given UIDs.
* IMPORTANT: Unlike the Java version of this API, unknown UIDs are
* not represented by 'null's. Instead, they are represented by empty
* strings.
@utf8InCpp String[] getNamesForUids(in int[] uids);
* Returns the name of the installer (a package) which installed the named
* package. Preloaded packages return the string "preload". Sideloaded packages
* return an empty string. Unknown or unknowable are returned as empty strings.
@utf8InCpp String getInstallerForPackage(in String packageName);
* Returns the version code of the named package.
* Unknown or unknowable versions are returned as 0.
