What is advantage of apklib from jar?

问题

I was following this question but it doesn't answer my question completely.

What is real advantage of apklib from jar?

Possible answers:

1. It contains resources

But I can easily put resources to jar file as well

2. It contains already prepared android classes

But if I open apklib I don't see dex or something other related to android. Even more I see plain sources inside.

So what is real purpose to keep/distribute library in apklib format?

No, you cannot, at least not in terms of the Android resource system. Being able to create a JAR (or similar package) that contains Android resources is one of the objective of the new build system that Google is working on at the present time.
