When an app is installed by the Package Installer app on behalf of another app (eg. a browser, file manager or app store that opens an APK via an activity start), it is preferable to attribute the install to the originating app rather than the 'Package Installer' itself. Since Android R, package manager keeps track of the necessary install source information which enables this more precise attribution. If an originating package is recorded and was set by a system app, we use this as the user-visible 'installer'.
