This won't work, because an Android Callable Wrapper will be generated for
LookupActivity<T> (as LookupActivity_1), but not for
LookupActivity<AmpachePlaylist>. Thus, when Android attempts to create a
LookupActivity_1, we'll attempt to run the managed side constructor, which will
fail as 'T' is unknown (and not knowable).
I'm not even sure if it's possible to make it work, either.
Finally, it doesn't make sense to me, as the purpose of an Activity (generally)
is to instantiate a single user-visible screen. By making it generic, you're
providing a _set_ of such activities, but the UI will still display only one
icon, so how is your app supposed to know which one of the set was desired?
