I don't know what to say, the code I pointed to is exactly what has been in
the platform fairly unchanged since 1.0 and has worked fine.
Are you sure you are doing this on a Context that is actually for your
application? The error message ("Invalid package identifier") indicates it
doesn't know *anything* about your application.
Also I wasn't pointing this code as something to directly copy and paste,
but as a guide. It comes from really deep down in the framework, so it is
not written as normal application code.
In fact if you copy and pasted the Resources.getSystem() part, that would be
your problem, because that is an API one doesn't normally use to get the
system-only resources. You should use the normal Resources object in your
app. (That's why the link I provided went directly to just the line pulling
out the resource data.)
