Hook after successful installation

I got an activi开发者_运维技巧ty that launches the package manager for installing an application contained in the phone's SDCard.

Is there some kind of hook that gets executed if the installation was successful|unsuccessful?

Thanks a bunch.

You might register something in your original application for broadcasts of ACTION_PACKAGE_ADDED (the newly installed application won't receive this broadcast)

Not sure if there's anything for failure (or user decision not to confirm the installation)
