The Intent documentation (which contains the broadcast action descriptions) explains what extras you can expect in the OS broadcast Intents.

http://developer.android.com/reference/android/content/Intent.html#ACTION_PACKAGE_ADDED

In any case, you can always call keySet() on the extras Bundle and see what keys are included that you can use to retrieve the data.
