collections

[etosch]

@jjfiv - what would it take to implement collections?

[jjfiv]

It looks like collections are heavily written in C/C++, so it would possibly be a lot of Javascript work.

So we're not going to be able to call anything that uses LinkedLists, etc?

Not likely. java.util. was kind of a minefield. I'd be happy to send you the files to look through, but I think it's out of scope for now (short of a few miracles)

[etosch]

So did the doppio people not do this?

They are using a slightly different JCL; it's possible that the non-Dalvik one is less native. I can take a look at this later.

IIRC they are using GNU Classpath.

I will see if I can dex and disassemble the collections library via the Doppio instructions later today. Their readme instructs you how to copy the classes from your installed JVM; they don't explicitly suggest Classpath.

I got the impression that Classpath died since the whole OpenJDK thing.
