Interesting - what type is "c"

Interesting - what type is "c"

that's what I came here to figure out :)

Ah, it threw an exception so I thought it was a bug. Since this is out of the realm of apktool I'll close the issue.

I haven't reviewed this yet, could be bug.

I have not. I have some bugs from 10 years ago :)

This was fixed in Apktool 3.0.0 during some of our type fixing. Sorry for delay.
